Two objects are sitting 150 meters apart and are not moving. Which best explains why the gravitational force does not cause them to move?

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
