An infrared spectrometer on Dawn found something unexpected on Ceres's surface. Its presence suggested that Ceres might have formed farther from the Sun, or been impacted by objects from a more-distant part of the solar system. What was this finding? a The presence of clay-like minerals with ammonia bound up in them. b The infrared spectrum of Ceres's surface is essentially identical to that of most obects in the Kuiper belt. c The fact that Ceres is covered with small dark particles that appear identical to the composition of Uranus's rings d The presence of a thick cloud layer made of sulfuric acid, similar to what is observed at Venus

You have negotiated with the Omicronians for a base on the planet Omicron Persei 7. The architects working with you to plan the base need to know the acceleration of a freely falling object at the surface of the planet in order to adequately design the structures. The Omicronians have told you that the value is gOP7=7.29 flurg/grom^2, but your architects use the units meters/second^2, and from your previous experience you know that both the Omicronians and your architects are terrible at unit conversion. Thus, it's up to you to do the unit conversion. Fortunately, you know the unit equality relationships: 5.24flurg=1meter and 1grom=0.493second. What is the value of gOP7 in the units your architects will use, in meter per second squared?
a. Calculate the surface temperature of Pluto and Charon at perihelion, assuming both bodies are rapid rotators and in equilibrium with the solar radiation field. b. Calculate the escape velocity from Pluto and Charon, and compare these numbers with the velocity of N2, CH4, and H2O molecules. c. Given your answers in (a) and (b), explain qualitatively the differences in surface ice coverage for Pluto and Charon.
Jupiter's moon, Io, loses about 1140.0 kg/s of sulfur dioxide to Jupiter's magnetosphere. At this rate, what percent of its mass would Io lose in 6.8 × 109 years? Io has a mass of about 1 × 1023 kg and there are 3.15 × 107 seconds in a a year.
The highest mountain on Mars is Olympus Mons, rising 22 000 meters above the Martian surface. If we were to throw an object horizontally off the mountain top, how long would it take to reach the surface? (Ignore atmospheric drag forces and use gMars = 3.72 m/s2.)
