Answer 4

Which describes what happens when a balloon is rubbed with a wool cloth?

A.
Electrons move from the atoms in the cloth to the atoms in the balloon, causing the balloon to have a negative charge.

B.
Electrons are shared equally between the atoms of the balloon and the atoms of the cloth, making both electrically neutral.

C.
Everyday objects do not have electric charges, so neither the balloon nor the cloth can gain or lose electrons.

D.
Electrons move from the atoms in the balloon to the atoms in the cloth, causing the cloth to have a negative charge.
