- 1. Multiple Choice
A student rubbed two different material non-metal with two different cloths.
He found that the two rods are attracted each other.
What is the most likely explanation?
The combination of rods transferred charges so that one rod had more positive charges and more negative charges on the other.
The combination of rods and cloths put positive charges onto both of the rods.
The combination of rods and cloths put negative charges onto both of the rods.
Both rods were neutral.

- 8. Multiple Choice
If you rub a balloon on a sweater, the balloon will stick to the sweater. Which of the following explains this?
Rubbing the balloon on the sweater builds up negative charges on the balloon. The balloon is then attracted to the positive charges on the sweater.
Rubbing the balloon on the sweater builds up negative charges on the balloon. The balloon is then attracted to the negative charges on the sweater.
Rubbing the balloon on the sweater takes all of the charges out of both the balloon and the sweater, therefore they stick together.
Rubbing the balloon on the sweater builds converts all of the protons and neutrons on the balloon and sweater into neutrons, and all of these neutrons stick together.
