3 forces acts on a 10kg mass . The first force pulls with 60N bearing 40°. The second force pulls with 80N, 60S of E. The remaining force pulls 100Non a bearing 290°. Determine the displacement of the mass 12s after moving from rest[0.14km, 35°N of W

Distinguish between a transverse wave and a longitudinal wave.

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 = ?

Which describes increasing the efficiency of energy resource
