QQ Is 0.0001 larger, smaller, or the same as 1.0 * 10**(-5)?
AA S 1  (1) Ten times larger
        (2) A hundred times larger
        (3) The same
        (4) A hundred times smaller
        (5) Ten times smaller

QQ What is 3.0 * 10**2 * 4.0 * 10**7?
AA S 1  (1) 1.2 * 10**10
        (2) 7.0 * 10**14
        (3) 1.2 * 10**15
        (4) 12.0 * 10**10
        (5) None of the other four answers

QQ Suppose you measure the angular size of an object that you think is
10 feet in width and located 100 feet away from you. You later
discover that the object is actually 20 feet in width and that it was
located 200 feet away from you. How should you modify your previous
measurement of its angular size, based on this information?
AA S 1  (1) Nothing changes. Both situations result in the same 
            angular size.  
        (2) You should cut it in half. 
        (3) All you can do is remeasure. 
        (4) There is not enough information to answer this question. 
        (5) You should double it. 

QQ Although it is the Earth that orbits the Sun, it appears to us that
the Sun moves around the Earth tracing a path among stars around the
sky in the course of a year. What is the name of the apparent path
followed by the Sun around the sky?
AA S 1 (1) Ecliptic
       (2) Equator
       (3) Zodiac
       (4) Equinox
       (5) Meridian

QQ What is the name for the collection of constellations through which
the Sun appears to pass as the Earth orbits the Sun?
AA S 1 (1) Zodiac
       (2) Zenith
       (3) Asterism
       (4) Leo and Gemini
       (5) Taurus and Torerus

QQ You are the only survivor of a ship wreck that manages to reach an
island in the middle of the ocean. You try to determine from the sky
where you are. What could you say about your location on Earth if you
find Polaris and estimate its altitude to be 70 degrees above the
north horizon? 
AA S 1 (1) You are at 70 degrees north latitude
       (2) You are at 70 degrees south latitude 
       (3) You are at 30 degrees north latitude
       (4) You are at 30 degrees south latitude
       (5) You are located on the ecliptic

QQ From which location on the Earth we cannot see circumpolar stars? 
AA S 1 (1) At the equator 
       (2) At the south pole 
       (3) At the north pole 
       (4) Nowhere 
       (5) At the north and south poles

QQ Suppose you lived on Mars instead of the Earth. Which planets would
appear to be inferior planets from your perspective?
AA S 1 (1) Only Mercury, Venus, Earth
       (2) Only Mercury, Venus
       (3) Only Jupiter, Saturn
       (4) Only Earth, Jupiter, Saturn
       (5) Only Earth

QQ Kepler's Third Law of Planetary Motion can be expressed as: P**2 =
a**3, where "P" is the orbital period of a planet orbiting around the
Sun in units of years, and "a" is the orbital semi-major axis in
Astronomical Units. You can see this equation works for the Earth
which has: a = 1 A.U., and P = 1 yr. Suppose a planet was discovered
orbiting another star that has the same mass as the Sun. If that
planet takes 2.83 years to complete a circular orbit around the star, 
how far does this planet orbit from its star? 
AA S 1 (1) 2.0 A.U.
       (2) 2.83 A.U. 
       (3) 4.76 A.U.
       (4) 5.2 A.U.
       (5) 100.0 A.U.

QQ Jupiter is 300 times more massive than the Earth and 5 times as far
away from the sun. According to Newton's gravitational force equation,
how much smaller or larger is the Sun's gravitational force on Jupiter
than it the Sun's gravitational force on Earth?
AA S 1 (1) 12 times larger
       (2) 12 times smaller
       (3) 60 times larger
       (4) 60 times smaller
       (5) none of the other four answers
