Suppose a distant world with surface gravity of 6.24 m/s^2 has an atmospheric pressure of 7.16 x 10^4 Pa at the surface.
(a) What force is exerted by the atmosphere on a disk-shaped region 2.00 m in radius at the surface of a methane ocean?
(b) What is the weight of a 10.0-m deep cylindrical column of methane with radius 2.00 m? Note: The density of liquid methane is 415 kg/m^3.
(c) Calculate the pressure at a depth of 10.0 m in the methane ocean.
