Two 10-hz, sine waves have a relative phase shift of 30 deg. what is the time difference between them? if the frequency of these sine waves doubles, but the time difference stays the same, what is the phase difference between them?

If forces acting on an object are unbalanced. true or false

In what direction does an applied force move an object

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 = ?
