Acrate of apples weighing 71.4 n sits at rest on a ramp that runs from the ground to the bed of a truck. the ramp is inclined at 20.0° to the ground. what is the interaction partner of normal force?
1. if the interaction partner is acting above the surface of the ramp, enter a positive value.
2. if the interaction partner is acting below the surface of the ramp, enter a negative value.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
