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

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

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

When Sally rubs her feet on the nylon carpet while wearing wool socks, static electricity builds up due to the transfer of electrons. The correct response is:

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

This is because wool is typically more negative than nylon, so during the rubbing action (friction), electrons transfer from the wool socks to Sally's body, resulting in her gaining a negative charge.
