Thank you very much! About the atmosphere "bleeding", I think that could be neglected because as you say it is not the most important part of the problem

Thank you! But do I not need the Gravitational constant for Pluto to do that calculation? If found an approximation on Wikipedia "Escape velocity" "For a body with a spherically-symmetric distribution of mass, the barycentric escape velocity ve from the surface (in m/s) is approximately...

Homework Statement Pluto is believed to have a radius of 1500 km, a mass of 1.5x10^22 kg, and a surface temperature of 55 K. Could Pluto support an atmosphere of methane, CH4? Homework Equations The Attempt at a Solution First some information: The problem is from a book...

Homework Statement A man is standing on a rotating plate (rotates without friction). In case A he is hold 1weight in each hand (straight out) with the mass m and he is rotatin with angular velocity omega_0. Then he moves his arms down so they are parallell to the body (case B) and increases...

[SOLVED] Equipartition theorem Homework Statement If the chlorine molecule at 290 K were to rotate at the angular frequency predicted by the equipartition theorem what would be the average centripetal force? (The atmos of Cl are 2*10^-10 m apart and the mass of the chlorine atom 35.45 a.m.u)...

Homework Statement ... Show that the entropy of the system in the microcanonical ensemble is W = \frac{N!}{n!(N-n)!}3^n and obtain an expression for the temperature of the system. ... N = number of molecules n = number of molecules in orthostate Homework Equations The Attempt...

I'm trying to show a formula for an ideal gas, but I don't get the right results. Homework Statement For an ideal gas PV = nRT where n is the number of momles. Show that the heat transferred in an infinitesimal quasistatic process of an ideal gas can be written as dQ = \frac{C_V}{nR}VdP...
