ASTRO 7N Exam 1 Questions and
Answers
What two properties of a planet affect the gravity we feel on its surface?
✓ ~~~mass and radius
If the frequency of radiation is twice as large then its wavelength is
✓ ~~~half as large
which would have the shortest day and longest year?
✓ ~~~a planet that rotates rapidly on its axis and orbits slowly around the sun
a particular zodiac constellation is high in the sky at midnight in April. Where will it be
in October?
✓ ~~~near the sun in the daytime sky
When does the New Moon set?
✓ ~~~sunset
If a telescope in space is only 1/4 the diameter of a telescope on Earth, which of the
following is true?
✓ ~~~the larger telescope can observe objects fainter than the space telescope
Consider a planet whose rotation axis is NOT tilted with respect to its orbital plane.
What are the seasons like on this planet?
, ✓ ~~~there are no seasons
Compared to ultraviolet radiation, X-rays have a wavelength that is:
✓ ~~~shorter
when is the best time for you to be able to see the constellation that is your sign of
the zodiac?
✓ ~~~at midnight six months after your birthday
the surface gravity on Jupiter is about three times as much as the surface gravity on
earth. This means...
✓ ~~~you cannot jump as high on Jupiter as on Earth
what phase is the moon in when it is observed by the person standing on the Earth
in the diagram above?
✓ ~~~Third Quarter
12 (picture)
✓ ~~~
Approximately two weeks after a Solar Eclipse, what phase will the Moon be in?
✓ ~~~Full
since the area of a circle is equal to pi times radius squared, if you double the width
of a telescopes circular mirror...
