You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.80 × 10 7 m and its rotation period to be 22.3 h. You have previously determined that the planet orbits 2.20 × 10 11 m from its star with a period of 402 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s 2 . What are the masses of (a) the planet and (b) the star?

The faster a molecule is moving in the upper atmosphere, the more likely it is to escape Earth's gravity.
Given this fact, and your knowledge of rms speed, which of the following molecules can escape most easily from Earth's atmosphere if they are all at the same temperature?
The temperature in one part of a flame is 2,100 K. What is the rms velocity of the carbon dioxide molecules at this temperature? Give your answer as the number of meters per second.
mass of 1 mole of CO2 = 44.0 grams
1 mole contains 6.02 x 1023 molecules
the Boltzmann constant k = 1.38 x 10-23 J/K
The specific heat of a certain substance is 375 J/(kg°C). How much heat energy would you have to add to increase the temperature of 22 kg of this substance from 33°C up to 44°C in a number of Joules?
