Sally puts on wool socks and rubs her feet on a nylon carpet. How does static electricity build up in Sally?(1 point)

Responses

The friction causes electrons from the wool socks to move to Sally, giving Sally a negative charge.

Electrons from the carpet move into the wool socks, giving Sally and her socks a positive charge.

When electrons from the wool socks move into the carpet, Sally and her socks gain a negative charge.

The correct response is:

Electrons from the carpet move into the wool socks, giving Sally and her socks a positive charge.

In this situation, the friction between Sally's wool socks and the nylon carpet causes electrons to transfer from the nylon carpet to the wool socks. As a result, the wool socks become negatively charged, while Sally and her socks (since they are in contact) will overall take on a positive charge due to the loss of electrons.
