Answers Verified 100% Correct
If you left a camera out to take time-lapse photographs of the moon for a whole
month, would you be able to photograph the Moon's entire surface? - ANSWER -
No, half of the Moon is always pointed away from Earth.
You observe a full moon rising at sunset. What will you see 6 hours later? -
ANSWER -a full moon on or near your meridian
When we see Venus in its new phase, what phase would Earth be in as seen by a
hypothetical Venetian? - ANSWER -full
Which of the following statements about the orbits of the planets is true? -
ANSWER -The eight major planets go around the Sun in the same direction and do
so all in the same plane like a disk.
According to Kepler's third law (p2 = a3), how does a planet's mass affect its orbit
around the Sun? - ANSWER -A planet's mass has no effect on its orbit around the
Sun.
Suppose the Sun were to shrink suddenly in size while its mass stayed the same.
According to the law of conservation of angular momentum, what would happen? -
ANSWER -The Sun's rate of rotation would speed up.
Imagine a Star Wars type spaceship in orbit around a planet. Its engine suffers a
severe malfunction, and explodes. What is the most physically realistic depiction
of this event? - ANSWER -The spacecraft breaks apart, and the pieces continue to
orbit the planet.
Conservation of angular momentum dictates that the orbital speed of a planet -
ANSWER -is faster when it is closer to the Sun and slower when it is farther away.
, How would the gravitational force between Earth and Moon change if the Moon
were moved 4 times further away? - ANSWER -The force would be 16 times
weaker.
Which planet is moving more slowly around the Sun? - ANSWER -Jupiter
Why are astronauts weightless in the Space Station? - ANSWER -because the
Space Station is free falling around the Earth.
The mass of Jupiter can be calculated by measuring... - ANSWER -...the orbital
period of one of Jupiter's moons and the distance between Jupiter and that moon.
The surface gravity on the Moon is about 1/6 that of Earth. What is the mass of a
72 kg person on the Moon? - ANSWER -72 kg
The acceleration due to gravity near the surface of the Earth is about 10 m/s2.
How fast is a rock falling if it has been falling for 3 seconds? - ANSWER -30 m/s
Light travels at 300,000 km/sec. About how far does light travel in 10 years? -
ANSWER -About 10 light-years
"Roses are red, violets are blue ... ". But why is this? - ANSWER -Roses reflect
more red light than other wavelengths, violets reflect more blue light than other
wavelengths
From lowest energy to highest energy, which of the following correctly orders the
different categories of electromagnetic radiation? - ANSWER -radio, infrared,
visible light, ultraviolet, X rays, gamma rays
One star is emitting primarily visible light and another star is emitting primarily
infrared light. Which star is hotter? - ANSWER -The star emitting visible light.
When you leave class on a sunny day, and see the grass and trees, how does this
work? - ANSWER -Some of the sunlight emitted by the Sun reflects off the grass
and trees, and enters your eyes.
