2. Atmospheric Mass Venus and Earth have about the same mass and radius, but the atmospheric pressure on the surface of Venus is measured to be 90 times larger than the pressure at the surface of the Earth. (a) Assuming Venus' atmosphere is pure CO2 and Earth's atmosphere is pure N2, estimate the atmospheric scale height for each planet. For simplicity you can assume that both atmospheres are isothermal with T = 550 K for Venus and T = 250...

A planet has a mass of M1, a radius of R1, and a density of Q1 A second planet has a mass of M2, a radius of R2, and a density of g2. This problem will explore the relationships between the surface gravities (g1 and g2) of the planets depending on the relative sizes of their masses, radii, and densities. Assume that planet 2 has X times the mass of planet 1, or M2 - XM1. The densities of both...
