Why is a dense cloud more likely to produce an elliptical galaxy than a spiral galaxy?
A) The higher density of gas has a stronger force of gravity, and therefore the cloud collapses more quickly. B) The thickness of the dense cloud prevents a disk from forming. C) The higher gas density forms stars more efficiently, so all the gas is converted into stars before a disk can form. D) The force of gravity can pull the material into a more spherical shape. E) The more frequent collisions between particles randomize the particle orbits.
Two objects, one of mass m and the other of mass 2 m, are dropped from the top of a building. When they hit the ground:

D) the heavier one will have half the kinetic energy of the lighter one. E) the heavier one will have one-fourth the kinetic energy of the lighter one.
