Conduction, Induction, Friction

A positive charge is brought near a neutral conducting rod. What will happen to the rod's charge distribution?

• electrons will move toward the balloon, negative charge on rod

• electrons will move toward the balloon, polarize, neutral rod

• protons will move away from the balloon, polarize, neutral rod

• electrons will move on the surface away from the balloon, polarize, neutral rod

A positively charged balloon is brought near an aluminum can, and a hand touches the can. How will electrons move?

• e- will move from the can into the hand away from the balloon

• e- will move from the hand into the can towards the balloon

• e- will move towards the hand, but stop at the end of the can

• e- will move towards the can, but stop at the end of the hand

• conduction

• convection

• radiation

The transfer of energy through matter by the direct contact of particles is called​ (a)   .

• conduction

• convection

• radiation

• kinetic energy

Answer explanation

Conduction is the transfer of energy through matter by direct contact of particles, making it the correct choice in this context.

How will charges move in the three rectangles?

• electrons will move all the way to the left and stop at the leftmost insulator

• electrons will move to the left and stop when they hit the first insulator

• electrons will not move
