Sally puts on wool socks and rubs her feet on a nylon carpet. How does static electricity build up in Sally?(1 point)
When electrons from the wool socks move into the carpet, Sally and her socks gain a negative charge.
The friction causes electrons from the wool socks to move to Sally, giving Sally a negative charge.
Electrons from the wool socks move into the carpet, giving Sally and her socks a positive charge.
