(c) The plastic tube is attached to a metal mast. This would cause the metal mast to become positively charged.
Explain why there is a wire connecting the metal mast to the Earth.

can someone please help by answering the question and not write anything ​

that would be b i just took the test : )

we need answer choices

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                                         : )
