ENGLISH LANGUAGE PAPER 1 for March 2014 ICSE Class 10 Examinations

Std. 10 Marks: 80 Time: 2 hours ___________________________________________________________________________________________

(Attempt all four Questions) Question 1. (Do not spend more than 35 minutes on this question) (a) Write a composition (350-400 words) on any one of the following: Most of us always remain stressed, suggest same ways to minimize it. Ans. These days everybody agrees to the fact that life is full of stresses and strains, wherever and whenever we meet people the topic of discussion generally revolves around changing life-styles, rat-race in all walks of life and how it is affecting our health. With more technological advancement and more mechnisation, the luxuries, no doubt, are much more at our disposal as compared to a decade ago. Yet it has not created a stress free environment. On the other hand there is an increase in the life-style disease such as hypertension, diabetes and cardiac diseases. The more mental pressure is actually resulting into a physical one also. Every age group of the society is under strain, it is high time we sit in silence and introspect to find as to what is ailing us. First and foremost is that we need to modify our life-style and learn the techniques to unwind and de-stress our self. The idea of meditation has just flashed my mind, as we do not need much equipment to perform it, and the results are great. It involves different breathing exercises. It is not difficult to learn as lots of literature in print and videos in visual form is available in the market or one can also learn from television, many channels show different programmes on meditation and yoga with proper techniques. What is actually meditation? In meditation we break the barriers of words, language, hatred and violence and we learn to vibe with each other mentally. If speech is silver, silence is golden, for in the vast treasure of deep silence can find a large source of peace and tranquility. In that moment of silence and introspection, we become conscious of our self and we try to analyse our thoughts. Another factor that has made man restless is alienation from nature. On this race of progress and materialism, man has lost touch with his own emotions. In spite of so much noise all around him, he is feeling empty and lonely. This sadness is eating him inside, having all the amenities, money and good things of life ---even then he is not happy. Some corner of his heart is yearning for that peace and love. By destroying nature gradually, man has nearly killed his conscious also. It is high time that man should learn from earth the quality of preservation and resurrection, how from dead remains a neglected small seed can give rise to plant. Just when it appears that everything is lost and we are downed and are under stress, that is the time to seek peace and tranquility through meditation and it is also the time to resurrect yourself like a tiny plant.

b) The commercialization of festivals has eroded their real significance. Express your views either for or against this statement. Ans. A festival is an occasion for rejoicing and celebration. It conjures up scenes of gaiety and merry-making. It is an occasion for family rejoicing and community celebrations. Festivals break the monotony of life, bring peace and joy to the masses and above all promote social interaction and harmony. All nations have their religious and colorful festivals. Being a multi-religious, multilingual and multi-racial country, Indians celebrate a number of festivals all through the year. However, Indian festival are known to attract the world due to their harmony variety, color and excitement. But now we see their significance has been eroded by their commercialization. Now these have become just important occasions, to promote personal and commercial purpose. We know, Indian festivals are as varied as the people themselves. All communities, all religions and all nations have their festivals. But nowhere do they form such an integral part of life as they were earlier used to be. These festivals can broadly be divided into three categoriesnational or political, religious and seasonal. Most Indian festivals usually have their origin either in religion or in the myths and legends of popular faiths. Some are connected with the memory of venerable men and events and are, therefore, commemorative in nature. They are intended to keep alive the memory of those days and personalities and inspire people to emulate their examples. But now, real purpose have been abandoned. In the name of those men and occasions, celebrating the event have become a means to attract funds, provided in the name of those functions. National festivals, like the Republic Day, the Independence Day, Gandhi Jayanti and others are supposed to be celebrated with great patriotic fevour. These have been declared as national holidays and are celebrated in all parts of the country and in the state capitals with a lot of pomp and show. The organizer of these functions never bother to follow the principles of those great men, i.e., of simplicism and non-violence, they rather fight with their coordinators to be ahead in the lime light. The capital, New Delhi is the seat of national celebration on all occasions. It witnesses one of the most majestic parades on the Republic Day. Apart from the Armed Forces, school children from across the country also participate in the parade. The normal practice is that the states exhibit their talents depicting the states resources or recent achievement and the best one achieve rewards. But now, it is an open fact that achievement has nothing to do with the reward. One, who has great source of authority, places can get the place in the line. Moreover, the glory of those reward doesnt last long. The winners steal the medias show for the time being. After a time, they are lost in commercial gloom as the commercializing agents make hay while the sun shines. The same is the case in religious festivals. Diwali is celebrated all over India. On this day, the people worship Lakshmi, the goodess of wealth. On this day, everybody illuminates his house with rows of lights. Every town or village appears gorgeous on this night of mirth and festivity. Lights of all descriptions from the ordinary clay lamp to the costliest chandelier are artistically displayed with splendid effect but the ordinary clay lamp to the costliest chandelier are artistically displayed with splendid effect but to show personal supremacy. In the larger cities, gas and electric lights of various colours and degrees of luminosity make the night as bright as midday without bothering that they are, more or less, misusing the necessary resources. Vocal and instrumental music, stage performances and cinema shows keep people awake till late hours. Fireworks are displayed on house-tops and the frequent whizzing of sky-rockets and explosive bombs continue to be heard from sunset to midnight.

The divine glory of the festival seems to have been lost behind all this show. For young merry-makers, the Diwali night is the ideal night. They spend lavishly on crackers and have sumptuous feasts. They never prefer to do some efforts to make the day memorable for those who have not pocket power to celebrate it. Sweets are consumed in huge quantities but not for sacred purposes. Juniors gift them to seniors to make them happy so that, in turn, they would get their favor. Many desecrations like these have crept into the celebration of this festival. The season of festivals is at its peak each year during the months of October and November. There may be poor souls lost in hectic routine having no idea of festive season. There are ump teem ways to remind one that the festival months have arrived. To begin with there would be numerous tents on roadside with bhajans blaring from the loudspeakers and temporary stalls serving piping hot food on payment. Then there are innumerable Dandiya with DJs that go on for nine days. Its time for brisk business for all. Shops, big and small display For Sale or other schemes to attract customers. Most of the Indian festivals which have come down to us from antiquity are connected with the course of nature and the fruits of the soil. Many legends from Hindu mythology have been associated with festivals. The relationships are the essence of celebrations. But does this spirit exist in todays fast paced competitive, nuclear families?

c) I heard a gentle knock at my door. Write a short story beginning with the above sentence.

Ans. I heard a sweet know at my door as I was busy finishing writing an article. What I saw was truly amazing, a girl ten to twelve years old was standing there. She was giving me a nice and pleasant smile, beaming from ear to ear. She was a thin framed child wearing a knee length dress and bare feet. There was uncanny yet friendly expression on her face which made me all the more curious about her. I asked her what does she wants? She did not ask anything but from her frail figure I could see the expression of satisfaction on her face that elated my heart immensely.

In some corner of my heart, I was feeling good after rendering a helping hand to one of the victim of the gravest natural calamity which was of recent happening and has rendered many people homeless. Many of them have just been washed away after the cloud burst in the torrential rain. Those alive have been brought to the streets to fend for themselves. I was also thanking god for selecting my door for that sweet and gently knock.

d) Study the picture and poem given below. Write a story or a description or an account of what it suggests to you. Your composition may be about the subject of the picture or may take suggestions from it; however, there must be a clear connection between the picture and your composition.

Ans.

H.No., 12, P.G. Road, Delhi-110002 June 1, 2004

Dear Mother, Hope this letter of mine will find you in good health. I am fine here and enjoying my college life. My college life is quite different from the school environment. On the first day, when I was going to college with a group of friends, we met an old man. He was bald and was rather shabbily dressed. He was arguing with an auto rickshaw driver, over mere two rupees. One of my friends told the old man to give the driver his proper due. I know why she had to interfere. She passed a few critical remarks at him, saying, she could not understand why some people were so stingy. Two of my other friends also joined her in passing remarks at him. The incident was soon forgotten and we reached the college. We waited in the classroom for our first Biology class. We were aghast, when the same old man, walked in. He was our Biology teacher! Mummy, you can imagine the state we were all in. In really, wished the earth would open up and swallow all of us. Our teacher behaved as though he hadnt known anything and taught us very well. We were extremely embarrassed. We are planning to write an apology letter to him and hand it over personally to him. We hope that he will pardon us. Please convey my regards to Daddy and accept them yourself too. Your affectionate daughter, Neerja

You seemed at first to take no notice of your school-fellows, or rather to set yourself against them because they were strangers to you. They knew as little of you as you did of them, so that this would have been reason for their keeping aloof from you as well, which you would have felt as a hardship. Learn never to conceive a prejudice against others because you know nothing of them. It is bad reasoning and makes enemies of half the world. Do not think or them till they behave ill to you; and then strive to avoid the faults which you see in them. This will disarm their hostility sooner than pique or resentment or complaint. I thought you were disposed to criticize the dress of some of the boys as not so good as yours. Never despite any one for anything that he cannot help never at all, for his poverty. I would wish you to keep up appearances yourself as defense against the idle sneers of the world, but I would not have you value yourself upon them. I hope you will neither be the dupe nor victim of vulgar prejudices. Instead of saying above, Never despise anyone for anything that he cannot help --- I might have said, Never despise anyone that you are glad and congratulate yourself on their familiar misfortunes. The sense of inferiority in others, without this indirect appeal to our self-love, is a painful feeling, and not an exulting one. You complain since, that the boys laugh at you and do not care about, and that you are not related as you were at home. My dear, that is one chief reason you may meet with in life. You cannot always be with me, and perhaps it is as well that you cannot. But you must not expect others to show the same concern about you as I should. You have hitherto been a spoilt child, and have been used to have your own way a good dela, both in the house and among your playfellows, with whom you were too fond of being a leader but you have good nature and good sense, and will get the better of yourself, and who have something else to attend to besides humouring your whims and fancies; and you feel this as a repulse or piece of injustice. But the first lesson to learn is that there are other people in the world besides yourself. There are a number of boys in the school where you are, whose amusements and pursuits (whatever they may be) are and ought to be of as much consequence to them as yours can be to you, and to which therefore, you must give yourself, you will only expose yourself to be the more thwarted and laughed at. True equality is the only true morality or true wisdom. Remember always that you are but one among others, and you can hardly mistake your place in society. In your fathers house you might do as pleased: in the world, you will find competitors at every turn. You are not born a Kings son to destroy or dictate to millions; you can only expect to share their fate, or settle your differences amicably with them. You already find it so at school; and I wish you to be reconciled to your situation as soon with as little pain as you can. Five words or phrases are given below. Give the meaning of each used in the passage: (i) think ill = think bad (of person) (ii) disarm = to give up your or take away someones weapon, demilitarize. (iii) despise = hate, detest. (iv) thwarted = frustrated, foiled. (v) amicably = in a friendly way. Answer the following questions in your own words:


7

i. The passage is addressed to a young school boy by an elderly person of great experience. What could be the relation between the two? Which sentence that gives the clue?

ii. Why do the school fellows after joining a new school keep themselves away from one another? iii. How do we make enemies of half the world? iv. Explain : The first lesson to learn is that there are other people in the world besides yourself. v. What is the idea implied when the writer says , You are not born a kings son?

vi. How can differences be settled amicably? Write a sentence suggesting one or two ways of setting differences.

Ans. (i) The relation between the two is of father and son. The sentence In your fathers house you might do as you pleased gives the clue. (ii) They keep themselves away from one another at the time of joining a new school as no one knows about the others. (iii) It is somewhat psychological that we grow some prejudices or form ill-founded opinions against those whom we do not know. The other party also does the same. Thus we lose the opportunity of befriending most of the people. (iv) One should not give oneself more airs of self-importance. In a big school, there are many boys with various interests and jobs. It is ridiculous to think that everybody will give to attend to you. So it is better to realize that you are not the only person in the world. (v) A kings son can do whatever he pleases. At ones home one can do, to a certain extent, what one pleases. But in a school, amid a larger group, one has to adjust oneself in the group. One has to share ones joys and problems with others. (vi) Differences can be settled amicably by meeting with one another, discussing, understanding others point of view and accepting ones mistakes, if any. In not more than 60 words of your own describe the main points of the advice given: Ans. One should not form prejudices against others without knowing about them fully well. Try to avoid others fault. Never look down upon anyone for his misfortunes. Do not take airs of self-importance. Consider everyone equally important. Remember you are one among others. You have to adjust with the group and share your joys and problems with them.

Rosalind lacks then the love Which teacheth thee that thou and I am one : Shall we be sunderd ? Shall we part, sweet girl ? No, Let my father seek another heir. Therefore devise with me how we may fly, Whither to go, and what to bear with us : And do not seek to take your change upon you, To bear your griefs yourself and leave me out; For, by this heaven, now at our sorrows pale, Say what thou canst, Ill go along with thee. Rosalind : Why, whither shall we go ?

(i) According to Celia, in what way has Duke Frederick indirectly banished her ? Ans. Celia loves Rosalind so much that she considers her as even closer than a sister, almost as two bodies

with one soul. She cannot even think of being parted from Rosalind. So she says that by banishing Rosalind, Duke Frederick has also banished Celia, his own daughter because Celia will not be separated from Rosalind. Wherever Rosalind goes, Celia will also go, even if it is into banishment.

(ii) Quote from the extract one line that shows that Celia has decided to break her relationship with her

father. Ans. The line is : No : let my father seek another heir.

(iii) Why does Celia tell Rosalind that the former is associated with the latter in sorrow ? Ans. When Celia asks Rosalind not to be more unhappy than she is Rosalind replies that she has more

cause for unhappiness than Celia. At this Celia says that it is not true because in banishing Rosalind the Duke has also banished Celia because the two of them are so joined together in love that they can never be parted.

(iv) Where do the cousins plan to go ? What danger do they foresee during the journey ? Ans. When the two girls are thinking of where they can go, Celia comes up with the idea of joining her

uncle and Rosalinds father in the forest of Arden. Rosalind is worried that because they are young and beautiful they will face danger on such a long journey. She says that beauty tempts thieves even more than gold does.


11

(v) What precautions do they plan to take against such a danger ? Ans. Celia and Rosalind decide to disguise themselves because it will not be safe for them to travel so far in

their own rich clothes and natural beauty. Celia says that she will dress in poor clothes and colour her face with a brown pigment called umber so that they can travel unnoticed. She suggests that Rosalind should do the same. Rosalind thinks that it will be better if she disguises herself as a man because she is so tall. She says that she will put on the fierce and boastful behavior of a man, whatever womanly fears may lie hidden in her heart.

Question 2.

Read the extract given below and answer the questions that follow : Rosalind : I have promisd to make all this matter even. Keep you our word, O duke, to give your daughter; You yours, Orlando, to receive his daughter; Keep you your word, Phebe, that youll marry me, Or else, refusing me, to wed this shepherd; Keep your word, Silvius, that youll marry her, If she refuse me : and from hence I go, To make these doubts all even.

(b) When Ganymede and Cilia leave the Duke comments to Orlando that the face of the shepherd boy, Ganymede, reminds him of his own daughters features, that he sees a resemblance to Rosalind in Ganymede.

(iv) Why did Phebe spurn the love of Silvius ? Under what conditions did Rosalind agree to marry Phebe ? What happens at the end ?


12

Ans. Phebe was very attractive and was proud of her beauty. She thought she was too good for Silvius and so spurned his love. Moreover, Silvius was doglike in his devotion and she wanted a strong and dominating man, which she thought she had found in Ganymede. Rosalind agrees to marry Phebe on the condition that if Phebe herself refuses to marry Ganymede, she will promise to marry Silvius instead. When Rosalind appears in her own clothes, Phebe realizes that Ganymede is actually a girl. She cannot possible marry a girl and so she marries Silvius.

(v) Briefly explain how Rosalind solved all the problems of the play. Ans. Since coming to forest of Arden Rosalind has been transformed from a sad and rather timid girl, always

conscious of her fathers banishment and her own position, into a lively, mischievous, witty and intelligent young woman. In this final scene, she takes full charge of the whole situation and gives evidence of her ingenuity. She shows herself to be a woman of action who fulfills what she promises. She produces the Dukes daughter and Orlando behaved so that Orlando is finally able to marry the woman he loves so deeply. She tricks Phebe into promising to marry Silvius in the event of her refusing to marry Ganymede. Since Ganymede is a woman and Phebe cannot marry her, Silvius gets the wish of his heart and marries his Phebe whom he loves with such devotion. Along with these couples, Touchstone and Audrey also get married.

setting sun. (ii) Why did the poet say or rather ? What happened earlier in the context ? Ans. Earlier in the context the poet had said that on her final journey in Deaths carriage, accompanied by Death

himself, they passed the setting sun. Then she realizes that she is already dead and the carriage is her hearse. Since she is dead, it was not possible for her to pass the setting sun. So she corrects herself by saying that it was not they who passed the setting sun, rather it was he who passed them. Like Death and Immortality, the setting sun has also been personified.

(iii) What did the passing of Deaths chariot by the setting sun show ? Ans. The setting sun signifies old age or the evening of life. The passing of Deaths chariot by the setting sun

shows that the poetess had passed her old age or the evening of her life. She was now dead and was travelling towards her grave.

(iv) What made the poet conscious of her thin dress ? Ans. The setting sun signifies the evening when the drew begins to fall and the night becomes chill. When the

poetess and death pass by the setting sun, she realizes that it is evening and she is wearing only a thin, gossamer gown. This signifies that she realizes that she is dead and the sudden realization chills her. Till now the journey has been so pleasant that she has not realized that she is dead.

(v) What was the destination of Deaths carriage ? Ans. The destination of Deaths carriage was a house. This house was actually the grave of the poetess, her final

resting place.

Question 6. Read the extract given below and answer the questions that follow :

Wide through the landscape of his dreams The lordly Niger flowed; Beneath the palm-trees on the plain Once more a king he strode; And heard the tinkling caravans Descend the mountain-road [The Slaves Dream by H.W. Longfellow]

(i) What happened earlier in the context ?


15

Ans. The slave was cutting and gathering the harvest of rice for his master and owner. His labour and the heat of the sun had exhausted him and he fell asleep just where he was in the field. As he slept he dreamt of his past life in his native land of Africa.

(ii) Which river did he see in his sleep ? How has it been described ? Ans. The slave saw the river Niger of Africa following in the landscape of his dreams. It is mighty river because it

has been described as wide and lordly. (iii) What did the slave see in his dream ? Ans. The slave saw his native land of Africa in his dreams. Through the landscape he saw the might river Niger

flowing. He saw the palm trees that grew on the banks of the river. (iv) Who was the slave before he was forced into slavery ? Ans. In his native land the slave had been a king, a tribal chief. He enjoyed both freedom and power and was

respected by his people. Now he has been sold into slavery is a total contrast from his previous one. (v) What were the sounds that he heard in his dream ? Ans. The slave heard the sweet tinkling of bells attached to the covered wagons in the caravan that were coming

down along the hilly road. Probably there were some of his own people returning to their village after transacting some business.

SECTION C --- PROSE

A Treasure Trove of Short Stories Question 7 Read the extract given below and answer the questions that follow : But her husband was on his hands and knees groping wildly on the floor in search of the paw. If he could only find it before the thing outside got in. A perfect fusillade of knocks reverberated through the house.

(i) Why was her husband looking for the paw ? Ans. The husband Mr. White was looking for the paw because he wanted to make his third wish. After the

death of their son it was very hard for them. Mrs. White found it very difficult to live without her son. So she asks her husband to make a second wish and get the son back which Mr. White does. But then when he heard the knocking at the door he becomes sure that it was his son but now he was afraid that his wife would not be able to see her son, because, due to the accident his body was mutilated beyond recognition. That is why he wants to wish that he be gone.

(ii) Why does Mrs. White rush to open the door ? Ans. Mrs. White was finding it very difficult to live without her son. By any means she wanted her son back

and that is why she even forced her husband to make his second wish. But in her grief she did not


16

realize how her son would look. She just wants him back. Now, when there is knocking at the door she is sure that her son has come back and she hastily goes to open the door.

(iii) Do you think that it was Herbert knocking at the door ? Ans. Once Mr. White had made his second wish he and his wife are waiting for something to happen. Along

with them the readers are also ready to believe that as a result of his second wish the visitor at the door was none other than their son Herbert. Because the first wish was granted now they as well as the readers are sure that the second one would also be granted. So I think it was Herbert knocking as the door though nobody is shown at the door. We can only guess that it was Herbert in his totally mutilated body at the door.

(iv) Was the third wish fulfilled? Ans. The third wish also seems to have been fulfilled. After the first wish the old couple received a sum of

two hundred pounds. It makes us believe that the monkeys paw had the magic spell about it. Second time after the wish there is knocking at the door which meant that Herbert had come and the knocking stopped soon and this is enough indication that the third wish was also granted.

(v) What is the lesson that the old fakir wanted to teach? Ans. The old fakir had put a spell on the monkeys paw. He wanted to show that fate ruled peoples lives

and that those who interfered with it did so to their sorrow. When Sergeant proffered the paw and told them how he got it, Sergeant Major had warned Mr. Morris by saying that if he must wish then he should wish sensibly and thus had invited their sorrow. They showed greed in asking for materialistic things like money, without realizing that they would have to pay a price for getting that money. Though the wishes are granted but all the three who used the paw regretted having asked for the wishes. In other words we can say that when we aspire for material things we might be happy only for a short while but in the long term they cannot make us happy rather they are the cause of pain and misery that human beings undergo.

Question 8. Write a note on the techniques employed by the writer to produce an atmosphere of horror in the story The Monkeys Paw.

Ans. The Monkeys Paw is a short story written by W.W. Jacobs. The story revolves around a mummified paw of a dead monkey which is a talisman that grants its possessor three wishes. The wishes come true but with an enormous price. To generate the enigma and horror the writer has implemented techniques of scene setting, choice of time when the incident occurs, use of situation and events, dialogues and description of the characters etc. that greatly contribute to build up the horror in the story.

One of the most effective techniques used by the writer, in the story is the setting. The opening scene is a cold, damp night in an English village on the edge of a moor. The house, Laburnum Villa is situated in a secluded out of the way place. It is isolated and lonely. It is winter and this scene is set at night and to add gloominess to the setting, it is raining. This description adds the dark tone in the setting, which signifies evil. Mr. White the owner is not at all happy with the location of his house as it is isolated. He calls his place beastly, slushy and out of the way, with this the writer prepares the readers for anything to happen. The opening scene where Mrs. and Mr. White with their son are in the sitting room, we are told


17

they are waiting for a guest. Throughout in the story an element of wait is added to bring about the curiosity. From the first scene to the last the Whites as well as the readers are anxiously waiting for something to happen. The strong wind blowing outside is suggestive of the impending doom. The storm outside prepares the readers for the storm to come in the lives of the three members of the family. The writers has very effectively used intermingling of the alternating mood of somber events, anxiety, grief, cheerfulness and light heartedness of the family which is unaware of the tragedy that is going to fall on them. The complicated situations and the simplicity of the nature of the characters bring that necessary contrast in the story which is very important. The technique of description of events or incidents, dialogues, narrations and actions are used effectively to build a feeling of horror. The explicit mention of far of oriental lands, and stories related to jugglers, magicians and fakirs, the mummified monkeys paw that has a spell cast on it, sets the mood for some super natural happening. The spell put by the old fakir that fate ruled peoples lives, and that, those who interfered with it did so to their sorrow, governs the whole story. They make the readers curious to know how this spell is interpreted in the story. The writer prolifically uses descriptions especially with adjectives and dialogues to create an eerie atmosphere like his blotchy face whitened, his tones were so grave that a hush fell upon the group, but I warn you of consequences, death, horror, but if you wish, wish for something sensible, the contrasting situation between outside The wind was higher than ever, and inside Silence unusual and depressing constantly generate apprehensions about the forthcoming events. The incidents like the movement of the paw like a snake on asking for the first wish and when Herbert is seeing faces in the fire add to the horrifying effect. The use of this incident that though Herbert pretends not to believe in the powers of the paw yet he is afraid, deep in his heart shows that the faces he sees in the fire are a projection of his own fears. The story ends when it is night and dark outside. By this time the readers have experienced varied emotions of happiness, gloom, sorrow, fear, horror, suspense and all these add to the setting of the atmosphere that the author is preparing us for. The element of supernatural is inter woven throughout the story and is so convincing that the readers also make up their mind not to interfere with the ways of destiny and fate. The writer has very effectively used the technique of foreshadowing. There are hints given to the readers from time to time about what is going to happen. Mr. White we are told is a very impatient man. he has been warned by Morris that he should be sensible while asking for a wish, he was not sensible and so the tragedy occurred. The writer W.W. Jacobs has used symbolism to create the desired effect. In the beginning there is a mention of the fire place which is symbolic of the warmth that exists in the family. When Morris throws the Monkeys Paw into the fire it suggests that he wants to get rid of the spell or magic put on it. When the tragedy is to fall on the family the candle in the room is blown out. This symbolizes the impending darkness that is about to prevail on the family. The oncoming hollowness, the emptiness and the desolation, in the lives of Mr. and Mrs. White are represented by the view of the deserted road, when she opens the door, and nobody is there, it is all empty and desolate. The climax of the story when Mr. White makes the second wish of getting his son back to life from grave and then the realization that dawns on him about how mutilated Herberts body was, he tries to convince his wife not to open the door at the knocks and then he seems to have actually matured when he makes a third wish of sending the ghost of Herbert back. The author has amalgamated different techniques of scene setting, mood setting, occurrence of events, dialogues, actions etc. perfectly well to successfully produce an element of horror in the story which can be almost perfectly visualized by the readers and enough to send a chill down their spines.

Question 9

After a robbery, if a window has been broken, there will be tiny particles of glass. Some of these will be found at the scene of the crime and some may be caught in the thiefs clothing. If the police can prove that these particles are identical, they have a strong case. A method of doing this is to suspend the particles of glass in a special liquid. Light of a single colour is passed through the liquid and the particles viewed through a microscope. The temperature of the liquid is then slowly altered. This alters the speed of light through the liquid (i.e. it alters the refractive index). At one particular temperature the particles of glass disappear. If this happens at the same temperature for both sets of glass particles, they probably came from the same broken pane of glass.

(a) Complete a copy of the diagram to show how light bends when it travels from the liquid to the glass and back to the liquid. (i) If the light slows down in the glass. (ii) If the light speeds up in the glass.

(iii) Is it possible to deflect -radiation in the ways that and particles can be deflected,

using electric or magnetic fields? (iv) What is -radiation thought to be?

when an -particle is emitted? (ii) By how much does the mass number of the radium nucleus in part (i) change? (iii) The new nucleus formed, when a nucleus of (226Ra88) emits an -particle is

identified as a nucleus of another element fairly close to radium in the periodic table. Identify this element from the data: Polonium (PO84), Astatine(At85), Radon(Rn86) and Francium(Fr87)

(c) What safety measures are needed in a nucleus power plant?

ANSWERS

Answer 1.

(a) The weight of the body (mg) = 350 Newton Total distance covered by the body = 30 x 20 cm = 600 cm = 6 metres = 350 N x 6m / 5 seconds = 420 watts (Answer)

(b) (i) Dioptre = Power of a lens. (ii) Kelvin = Absolute temperature

(c) The magnitude of a non-contact force depends on distance. (d) (i) The centre of gravity of a ring is situated at the centre of ring.

(ii) The centre of gravity of a rectangular lamina is situated at the point of intersection of its diagonals.


38

Answer 2.

(a) Constantan is used for making wires of standard resistance because the resistance of constantan remains almost unaffected with the change in temperature.

(b) Land cools at a faster rate than water because water has high specific heat capacity. (4200 J/KgC)

(c) Steam at 100C condense to water at 100C loosing considerable amount of energy equal to its latent heat of vapourisation (2268,1/g).

(d)

(e) No

Answer 3.

(a) 220 volts.

(b) The concave cylindrical magnet (i) Intensifies the magnetic field. (ii) Makes the magnetic field uniform. This helps is setting a strong deflecting couple.

(c) Given : a1:a2 = 4 : 9 or I1 : I2= 42 : 92 = 16 : 81

(d) Given : f= 0.25 MHz = 0.25 x 106 Hz = 2.5 x 105 Hz T= 1

= 12.5105

= 105

2.5 = 4 x 10 -6 seconds.

(e) Nichrome wire is used for electric heater element because it has high resistivity and high melting point.

Answer 4.

(a) Since I = E/ (R+r)


39

For the current delivered by a cell to be maximum (to have less potential difference across it) the internal resistance (r) should be minimum.

(b) Green light. (c) (i) Yes

(ii) No, the speed of red colour is greater than blue colour in the glass. (d) Power = 2.5 KW V = 250 V

Energy in KWh = P x T = 2.5 KW 2h = 5 KWh Cost = 0.60 x 5 = Rs. 3 (Answer)

(e) -particles given out from a radioactive source are able to pass through 2 mm aluminum block, while and - radiations are unable to penetrate through. So it produces faint radiation. Lead does not allow any of the , or radiations to pass through, so it produces dark shadow.

SECTION 2

Answer 5.

(i) Mass of the drum = 80 kg. and g = 10 m/s2 Force of gravity on drum = m g = 80 x 10 = 800 N.

(ii) Force of gravity on drum = 800 N. Total distance covered = 0.8 m Work done by the driver = Force x Distance = 800 x 0.8 m = 640 J. Energy converted = m g h = 640 J.

(iii) When the force needed to push a drum up the plank is 300 N which is less than the answer to part (i) because plank make an angle with the road thus making an inclined plane which decreases the force or the efforts acting on the drum to push it up into the truck.

(iv) The force exerted by the engine of the truck moves the truck and this work done by the force changes into K.E. of the truck

(v) When the driver has to stop at the factory gate this K.E. is converted into the work done by the resisting force to stop the truck.


40

Answer 6.

(a) (i) A musical note is one which leaves a pleasing effect on the ears. Such a sound is generated by periodic and regular vibrations. Whereas noise is a sound that produces an unpleasant effect on the ears. A noise is produced by non-periodic and irregular vibrations accompanied by an abrupt change in frequency or wavelength. (ii) Frequency (f) : The Frequency of sound is the number of complete vibrations made by a vibrating particle of the medium in one second. The S.I unit of frequency is hertz (Hz). f = 1/T where T is periodic time. Wavelength () : Wavelength is not the number of complete vibrations made by a vibrating particle but it is the distance covered by one wave. It is also defined as the shortest distance between two particles vibrating in the same phase. Its S.I. unit is metre, while that of frequency is in hertz. = / f

(b) Wavelength corresponding to the given extreme frequencies = /f = (330 m/s)/(20 Hz) = 16.5m longest = /f = 330/20.000 = 0.0165m shortest Ans. (i) The two prongs of a tuning fork set each other in resonant vibrations which help to maintain the vibrations for a longer time. (ii) While crossing a hanging (or rope) bridge, soldiers are asked to break steps because if they are up in steps, all the separate forces being in the same phase, will produce strong energetic vibrations of a particular frequency. If the natural frequency of the bridge becomes equal to the frequency of the steps, the bridge will vibrate will larger amplitude due to resonance and hence the bridge might overturn or crumble down.

Answer 7.

(a) The current gets back to the battery since the metallic body of the car acts as the other terminal through which the current comes back to the battery after completing the circuit.

(b) In order to make an electric contact, the paint which acts as an insulator, must be removed from the body where the electric contact is made.


41

(c) (i) The two rear lights shine dimly. It may be due to the fact that the two rear light are connected in series. (ii) See the circuit diagram below:

(d) Each bulb is labelled 12V, 4W, this means that when :

(i) Each of the bulb is connected to a supply of 12W, the power consumed by each bulb is 4W. (ii) Since the lights are supposed to be connected in parallel p.d. across each is 12V. Since P = Vt i = P/V = 4/12 = 0.33 Amperes. Total current supplied by the battery is (0.33 + 0.33 + 0.33 + 0.33 + 0.33) Amp. = 0.33 x 5 = 1.65 Amp.

(e) If the car starts, when the lights are on, the light go dim because a part of the e.m.f. is used in operating the self starter.


42

Answer 8.

(a) (i) First echo is heard from the nearest cliff. Let d1 be the distance of the nearest cliff from the person. Total distance travelled in going and coming back by the sound = 2d1 = 2 x 640 m = 1280 m Time interval t = 4s Speed of Sound = Total Distance Traveled / Time Taken = 1280 / 4s = 320 ms-1 (Answer) (ii) The second echo is heard from the farther cliff. If d2 is the distance of the farther cliff from the person, then total distance travelled by the sound in going and coming back = 2 d2 Time taken t = 4 + 3 = 7 s

Hence distance between the two cliffs = d1 + d2 = 640 + 1120 = 1760m.

(b) Steam causes more serious burns than that of water at 100C because 1g of steam at 100C imparts 2260 J of extra heat than the heat imparted by 1g of water at 100C.

(c) (i) Mass of water = 0.2 kg T1 of water = 65C T2 of water = 45C T (or fall in temp. of hot water) of water = 65C - 45C = 20C. Specific heat of water = 4200 J/kg C Heat energy released by water = mc t = 0.2 kg x 4200 J/kgC x 20 = 0.2 x 4200 x 20 J = 16800 or 1.68 x 104 J. Ans (ii) m = 1.5 kg of brass T1 15 C of brass T2 45C of brass


43

Heat gained = 1.68 x 104

t = 45C - 15C = 30C Heat gained = mc t 1.68 x 104 = 1.5 x c x 30 Heat gained by brass container per 0C rise in temperature.

1.68 x 10430

= 1.5 (iii) From (ii) 1.68 x 104

30 =1.5 c

= 1.68 10430 1.5

= 1680045

= 373.3 j/kgc

Answer 9.

(a) (i) When light travels from liquid to glass i.e., from rarer to denser medium, it bends towards the normal. (ii) When it travels from glass back to the liquid, it bends away from the normal because now light travels from denser to rarer medium.

(b) A single colour light is used in the police work because there will be only deviation and no dispersion causing inconvenience in taking observation.

(c) The two circumstances, when light travelling from liquid to glass may pass straight, are : when the incident light is perpendicular to the glass surface while travelling from liquid to glass. Also at a particular temperature, when the particles of glass disappear, the mixture acts as a homogeneous medium of definite refractive index. Under such circumstances, light will pass straight without bending.

(d) The particles of glass disappear at one particular temperature when the refractive index

of liquid and the mixture of the liquid and glass particles happen to have the same value. If exactly the same results are obtained by using glass particles found at the scene of crime and those found in the thief s clothing, the police can correctly come to the


44

conclusion that the person caught is the real thief and the observations of the above experiment bear a testimony to the police enquiry.

Answer 10.

(a) (i) The ionising power of -radiation as compared with - and -particles is about 1/100 times that of the partic1es and 1/10000 times that of the -particles. (ii) -radiations are highly penetrating. Their penetrating power is about 100 times that of (7i- particles and 10000 times that of -particles.

(iii) They are not deflected by electric and magnetic fields.

(iv) -radiation are electromagnetic radiations of short wavelength shorter even than the wavelength of X-rays.

(b) (i) The atomic number of a radium nucleus decreases by 2 on emitting an -particle. (ii) The mass number of a radium nucleus decreases by 4. (iii) Equation for alpha emission is

The element is Radon 86

(c) The following are the safety measures needed in a nuclear power plant : (i) The nuclear reactor must be shielded with lead and steel walls so as to stop radiations from escaping out to the environment. (ii) It should be housed in an airtight building of strong concrete structure which can withstand earthquakes, fires and explosion. (iii) There must be a back-up cooling system for the reactor core, so that in case of failure of one system, the other cooling system could take its place and the core is saved from overheating and melting.
