55:14 In 2010, scientists obtained an image of an asteroid that was dangerously close to Earth Which technology did the scientists likely use to capture the image? GPS, because it uses satellites that provide position and velocity data

radio telescope, because it captures radio waves from space

MRI, because it uses magnets to produce a picture

submarine communication, because it uses LF radio waves

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 = ?
