Wind blowing across suspended power lines may
cause the power lines to vibrate at their natural
frequency. this often produces audible sound
waves. this phenomenon, often called an
aeolian harp, is an example of
(1) diffraction (3) refraction
(2) the doppler effect (4) resonance

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
