If you enter 488.7 x 560 into a calculator, you get 273672. This is the answer expressed in correct
sig figs:
You have an object with a density of 5.00 g/cm3 and a volume of 15 cm3.
This is the mass of that object.
Object A has a density of 3.14 g/mL. Object B has a mass of
180 g and a volume of 130 mL. This is the denser object:
The image to the right depicts a density column containing 4
fluids in layers: A, B, C, and D. You know that you poured in four liquids with the densities 0.09 g/mL, 3.21 g/mL, 0.78
g/mL and 1.54 g/mL. Which liquid has which density?
A
B
C
D
DAILY DOUBLE!Both teams will have time to work on
this question, you need not be the first raised hand to answer it.
Choose up to 1000 points to wager. Your wager must be less than your
current point total.
You have a tank filled with oxygen gas. You force even more oxygen into this tank,
doubling the mass of the oxygen in the tank without changing its volume. What happens to the
density of the oxygen?
A car traveling at a given speed covers 1170 km in 18 hours. Use equal ratios to show how much
ground the car could travel in 34 hours at the same speed.
Newton operated off of a model of the solar system which had the
planets orbiting around the sun. The model he used is called a
____centric model.
The diagram shows an attempt to measure a tree’s height (T) by
measuring the length of its shadow (TS) and the shadow (OS) of an
object (O) of known height. Show one way to set up an equal ratio for
this problem.
T O
TSOS
A massive, powerful explanation in science is called this, while a
description of a relationship between two quantities is called that.
A scientist wants to know if birds sing different songs at different
air temperatures. To test the effect of air temperature on
birdsong, she records the songs of 60 captive male field sparrows after adjusting the temperatures of their individual enclosures.
Identify her independent, dependent, and a control variable.
Independent: Air temperatureDependent: Birdsong
Controls: All field sparrows, all in their own enclosures, all males, all
captive birds
If two waves have constructive interference, this is what the
amplitude of the resulting wave will be.
If a seismic wave travels at 65 m/sec, and each wave cycle lasts for 18 seconds, this is the distance from crest-to-crest or trough-to-trough.
A light photon (wave) that is higher in energy will have ____ frequency and
____ wavelength, and so it will be closer to _____ on the visible light spectrum.

Speed = m/sec, miles/hr, etc.Wavelength = m, in, km, etc.Amplitude = m, in, km, etc.
Period = sec, min, hrFrequency = cycles/sec (Hz)
These are the four major layers of the Earth, from shallowest and least
dense to deepest and most dense.
Answer may include: Northern/Southern Lights, protection from solar wind and space particles, navigation by some animals, human
navigation by magnetic compass
The Big Bang Theory states that the universe is _____. A key piece of evidence is that starlight is shifted towards the ____ end of the visible spectrum, which the Doppler Effect tells us means the stars are moving
______ us.
These are the states of matter of the inner core, outer core, mantle, and
crust. And the layer responsible for our magnetosphere is the _____.
In the Northern Hemisphere, the shortest day of the year is marked
with this number in the diagram, and it has this name.
