5. A flask of gas, volume V, is sealed by a light, frictionless stopper in a narrow side tube from the main flask (see diagram). The stopper is displaced inwards by a small distance 8x. If all changes to the gas are adiabatic, show that the subsequent motion of the stopper is simple harmonic with period, mV1/2 27 T = A (1 үр where A is the cross-sectional area of the stopper, y is the ratio of principal specific heat capacities of the gas, and p is the gas pressure. p Stopper, mass m V P ex V+8V p+op
