Questions And Verified Answers
How does the Moon move through the sky over the course of one night? -
correct-answer -Rises in the east and sets in the west because of earth's rotation
How does the Moon move through the sky over the course of half a lunar cycle at
the same time each night? - correct-answer -West to east because revolution
around the earth
Solar System - correct-answer -(Planetarium Lab)
Describe the method used to determine the relative sizes of Mercury's and Venus'
orbits by observing setting times. - correct-answer -We took the time that
mercury or venus set and subtracted it by the time sun set and then multiplied
that by 60 minutes to convert the time into minutes. In order to find out what
orbit was bigger we took the time elapsed b/w the sunset and the time that venus
or mercury set and divided those two numbers with the biggest number divided
by the smaller one. We use this method based on simple observations to
determine the relative sizes of their orbits.

Discuss how and why Venus changes its appearance to us on Earth over the course
of several months. - correct-answer -Because as venus and earth orbit the sun,
they sometimes end up far away from one another and sometimes closer to each
other.
Discuss the similarities and differences between the planetary orbits and the
dwarf planet orbits. - correct-answer -A dwarf planet is not big enough to have a
distinct orbital path, nor does it orbit another object, like a moon as other planets
do.
When you were taking data in the virtual observatory, what was the point of
accumulating it until the Signal-to-Noise ratio was greater than 100? (Stellar
spectra classification lab) - correct-answer -
Describe the method by which you classified the star whose spectrum you took. -
correct-answer -Compared to show standard spectra of stars. Viens law
By looking at the spectra of a few different stars, could you tell which is hotter?
Cooler? - correct-answer -Yes.?
