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

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.
