A loudspeaker contains an electromagnet that switches on and off very rapidly. This causes the cone of the speaker to move forwards and backwards very quickly. Use this information and your knowledge of sound to explain why you are able to hear the sound from the sound from a loudspeaker. *

Because of the vibrations from the loudspeaker

Explanation:

the answer would be c

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
