Paulina Burke · Answer 1

I would think That the answer Is C.

The reason being is that when a rubber balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge, and leaving the hair with a net positive charge. As the balloon is pulled away, the opposite charge on the hair causes it to be attracted to the balloon, And Katie's hair started to attract to the balloon before it even touched her. So this meant that a a specific distance, it would be able to attract.

C. Electric attraction is a force that can act at a distance.

Explanation:

Forces Acting at a Distance. Magnetic, electric, and gravitational forces can be exerted, even though the objects involved do not touch each other. For example, a magnet may pull a paper clip toward it without actually touching the paper clip.
