Consider an ideal monatomic gas of n particles with mass m in thermal equilibrium at a temperature t. the gas is contained in a cube of side l whose top and bottom are parallel to the earth’s surface, and the gravitational acceleration is a constant g throughout the box. (a) what is the average kinetic energy of an atom of this gas?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
