Physics 160 test 4 Exam 2026 Questions
and Answers
why do we have to enlist amateurs to measure an occupation? - Correct answer-the
occultation time depends on the position of the observer in the path of the shadow
in what direction is the storm rotating CW or CCW? - Correct answer-CCW as can
be inferred from the wake of the storm. this was confirmed by the space probe
voyager 1 that took a time-lapse of the storm.
is it south or north of the equator? - Correct answer-south of the equator
what is the hedgehog theorem? and how does that explain the storm we have? -
Correct answer-if you have a wind on a spherical surface, there must be a vortex
somewhere. also think of this as a "no-comb" theorem.
how was it possible to reach Saturn in only 7 years? - Correct answer-the slingshot
effect was used to take advantage of the rotation of Venus, earth and Jupiter.
what kind of power did it use? solar panels? why? - Correct answer-nuclear. the
sun radiation is too weak for solar panels at Saturn's distance.

, what feature of Saturn is called after Cassini - Correct answer-the large gap in the
rings.
mercury - Correct answer-is the fastest roman god.
only has an exosphere.
liquid/molten interior of metal.
1/3 the size of earth.
no moons.
magnitude (max) -2.48
venus - Correct answer-the god of love.
thick atmosphere.
solid/molten interior of metal (uncertain)
almost the size of earth.
no moons
magnitude (max) -4.14
what is the meaning of a negative magnitude? - Correct answer-contrary to what
you might think, the larger the number the fainter the star. negative numbers are
very bright objects.
