Adapt the kinetic theory (that we used to derive the ideal gas law) to derive a formula for the pressure exerted by a gas of photons. n photons are in a box of volume v with perfectly reflecting walls. each photon has energy ey = hv , where h is planck's constant and v is a fixed frequency. recall that the magnitude of the momentum of a photon is given by p = h/1. express the pressure p in terms of n, v, and ey. how does this compare with the corresponding expression for an ideal gas?

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.
