1. Eclipses can occur only at:
a. new moon
b. full moon
c. new moon or full moon
d. either quarter moon
e. e.
2.Newton's Universal Law of Gravitation states that objects in the universe attract each other with a force that varies directly with:
a. Their distances from each other
b. The Jupiter effect
c. The square of their distances from each other
d. Your astrological sign
e. The product of their masses
3.Asteroid A orbits the Sun at a distance of 4 A.U. while asteroid B, which is one-half as large as A, orbits at 8 A.U. Which asteroid will take longer to go around the Sun according to Kepler’s Third Law?
a. asteroid A
b. asteroid B
c. neither; both will take the same time
4.Polaris, the North Star, does not appear to move during a 24 hour period in the sky because:
a. The stars are fixed relative to each other.
b. It lies approximately over the northern axis of Earth.
c. It is too nearby for its motion to be discernible.
d. It is located directly overhead for everyone on Earth.
5..Planet X has its rotation axis perpendicular to its orbital plane (That means it has no tilt. Earth’s tilt is 23.5 degrees). Planet X’s seasons would be:
a. shorter than those on Earth
b. longer than those on Earth
c. the same as those on Earth
d. constant in both hemispheres
6.Which of the following describes parallax?
a. It is inversely proportional to an object’s distance.
b. It is an ancient method of finding distances, no longer useful today.
c. It can be used only with the most remote objects in space.
d. It is a method of measuring the length of small objects such as pencils.
7.__________ is the motion of Earth about its internal axis, and __________ is the motion of Earth about the Sun.
a. rotation/revolution
b. revolution/rotation
c. precession/revolution
d. d.
