the probability density function (pdf (often called a maxwellian distribution) that describes the speed v of molecules in a n ideal gas is given by: 3/2 4 m p(v) here m is the mass of the molecule, k is the boltzmann's constant, and tis the temperature a) show this is a properly normalized pdf. b) find the most probable speed c) find the average speed d) find the variance of the speed

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
