•Question 1: (1 point) If you were kidnapped and transported to a distant
location on Earth, but noticed that
Polaris was 20 degrees above the horizon, what could you figure out about your
•*3.* The latitude of my location is 20 degrees north
•Question 2: (1 point) If the moon rose at about 7pm one night (and you know
now that its phase would be
full or close to full, right?), at about what time will the moon rise the next
•*3.* 7: 45 PM
(Note this can vary because of the moon’s elliptical orbit).
•Question 3: (1 point) Imagine that you're kidnapped by aliens and transported
to a distant world in a different
solar system. They will release you if you show your understanding of orbital
dynamics. There is a planet
with a period (year) 8 times longer than the planet you are on. How much
further away is it from the
•*2.* 4 times as far.
•Question 4: (1 point) What is the circular velocity of Mercury?
•*3.* About 50 km/s.
•Question 5: (1 point) What is the correct order that shows increasing photon
energy for wavebands of the
–*1.* Radio -- Infrared -- Optical
-- Ultraviolet -- X-ray -- Gamma Ray
•Question 6: (1 point) The textbook talks about the resolving power of optical
telescopes on page 75, but
resolving power also depends on the wavelength of light being collected. The
resolving power is proportional
to the ratio of the wavelength to the telescope diameter
(wavelength/Diameter). Which telescope
has the best theoretical resolution?
•* 4.* The 10-meter Keck telescope operating in the optical
at 500 nanometers.
