If a transformer has a primary with 100 v and fifty coils, and a secondary that yields 20 v, how many coils are on the secondary? a.) 200 b.) 20 c.) 50 d.) 10 e.) 100

there are no correct statementd on the list of choices you provided.

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                                         : )
