A hockey puck moving at 0.4600 m/s collides with another puck that was at rest. The pucks have equal mass. The first puck is deflected 38.00° to the right and moves off at 0.3400 m/s.

In static electricity what are the subatomic particles, their charges, their location in the atom

How does resistance affect the current in a circuit?

The period of a cepheid variable star and the time of one recent maximum can be used to predict the time of a future maximum. suppose that you calculate the time of future maximum brightness and then make measurements to observe this maximum.

An Ohmic material is one in which its resistance does not depend on the voltage across it or the current within it. In that case, the resistance does NOT depend on:
