Which statement best describes why the Milky Way is shaped a certain way? The gravitational forces from the center of the Milky Way cause stars and solar systems to orbit around the center of the galaxy.

The gravity from the sun causes all of the other stars and solar systems to orbit it.

The Big Bang caused the Milky Way to form into the supernova we see today.

The inertia of objects in space makes them travel far distances.

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 = ?
