Asilver wire 2.6 mm in diameter transfers a charge of 420 cin 80 min. silver contains 5.8 *10^{28} free electrons per cubic meter.
what is the current in the wire?
what is the magnitude of the drift velocity of the electronsin the wire?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
