Share an example of elastic potential and kinetic energy. Clarify the points at which it changes.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

Four identical lab carts each have a mass of 200 kg. different masses are added to the carts and the velocities are measured. all carts move to the right.

Imagine that the rightward current flows in the rod for a short time. as a result, what will the net charge on the right and left ends of the rod become? left end negative and right end positive left end negative and right end negative left end negative and right end nearly neutral left end nearly neutral and right end positive both ends nearly neutral
