How are the magnetic domains of a magnet different from the domains of an ordinary piece of metal?

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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

hope that                                         : )
