Correct Answers
Why do we see essentially the same face of the Moon at all times? -
| | | | | | | | | | | | | | |
CORRECT ANSWER✔✔-because the Moon's rotational and orbital
| | | | | | |
periods are equal | |
What term is used to characterize the distance a planet orbits its star
| | | | | | | | | | | | |
when dealing with ellipses? - CORRECT ANSWER✔✔-semi-major axis
| | | | | | |
Why did Ptolemy have the planets orbiting Earth on "circles upon
| | | | | | | | | | |
circles" in his model of the universe? - CORRECT ANSWER✔✔-to explain
| | | | | | | | | |
the fact that planets sometimes appear to move westward, rather than
| | | | | | | | | | | |
eastward, relative to the stars in our sky
| | | | | | |
The ancient Greek philosophers realized that if the Earth moved around
| | | | | | | | | | |
the Sun then we would see small variations in the angular positions of
| | | | | | | | | | | | |
nearby stars, a variation astronomers call - CORRECT ANSWER✔✔-
| | | | | | | |
parallax
Which state has the longest summer days and winter days? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-Vermont
,What is the ecliptic celestial line? - CORRECT ANSWER✔✔-the Sun's
| | | | | | | | | |
apparent path along the celestial sphere
| | | | |
A comet can have two tails - CORRECT ANSWER✔✔-True
| | | | | | | |
There are twelve constellations in the zodiac - CORRECT ANSWER✔✔-
| | | | | | | | |
False
What causes the apparent retrograde motion of the planets? - CORRECT
| | | | | | | | | |
ANSWER✔✔-As the Earth passes another planet, the other planet
| | | | | | | | | |
appears to move backward with respect to the background stars, but
| | | | | | | | | | |
the planet's motion does not really change.
| | | | | |
The Moon orbits the Earth in approximately one month, moving in the
| | | | | | | | | | | |
same direction as the Earth orbits the Sun. Thinking about the relation
| | | | | | | | | | | |
between phase, position and time of day, about when would a first-
| | | | | | | | | | |
quarter moon rise? - CORRECT ANSWER✔✔-noon
| | | | |
Tycho Brahe made several naked eye observations, but NOT of: -
| | | | | | | | | | |
CORRECT ANSWER✔✔-the satellites of Jupiter
| | | |
It is the summer solstice. This means: - CORRECT ANSWER✔✔-Summer
| | | | | | | | | |
is starting in the northern hemisphere and winter is starting in the
| | | | | | | | | | | |
southern hemisphere |
, The angular diameter of the full moon can change by 50% during a year
| | | | | | | | | | | | | |
due to its ellipsoid orbit: - CORRECT ANSWER✔✔-False
| | | | | | |
Which of the following never goes in retrograde motion? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-The Sun |
If two planets have the same angular diameter but one is four times
| | | | | | | | | | | | |
farther away, then the more distant is...times larger than the closer one
| | | | | | | | | | |
|- CORRECT ANSWER✔✔-4
| |
Kepler's third law, P^2 = a^3, does not imply one of these: - CORRECT
| | | | | | | | | | | | | |
ANSWER✔✔-the period of a planet does not depend on its distance | | | | | | | | | | |
from the Sun| |
Tycho Brahe suggested a model with the Sun at the center of the Solar
| | | | | | | | | | | | | |
System - CORRECT ANSWER✔✔-False
| | |
Kepler found that the period P of a planet's orbital motion around the
| | | | | | | | | | | | |
Sun was related to the planet's "average" distance a from the Sun
| | | | | | | | | | | |
according to the following proportionality equation: P^2 = a^3. What
| | | | | | | | | |
would be the approximate period for a planet located at 4 times the
| | | | | | | | | | | | |
Earth's distance from the Sun? - CORRECT ANSWER✔✔-8 years
