Amonatomic gas is measured to have an average speed of 1321 m/s. if the total amount of the gas is 5 mol (which equates to a mass of 0.02 kg), what is the approximate temperature of the gas? (recall that the equation for kinetic energy due to translation in a gas is translational = mv2 = nrt, and r = 8.31 j/(mol a. 350 k b. 300 k c. 280 k d. 320 k

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.

Two balls, each with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in the collision? explain why or why not
