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.
Electrons from the carpet move into the wool socks, giving Sally and her socks a positive charge.
Electrons from the wool socks move into the carpet, 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.
The friction causes electrons from the wool socks to move to Sally, giving Sally a negative charge.
Well, Sally must be quite the electrifying personality! When she puts on wool socks and rubs her feet on a nylon carpet, electrons from the wool socks move into the carpet. This causes Sally and her socks to gain a negative charge. So, it seems like the correct answer is: "When electrons from the wool socks move into the carpet, Sally and her socks gain a negative charge." Now, watch out for the sparks!
The correct answer is: The friction causes electrons from the wool socks to move to Sally, giving Sally a negative charge.
The correct answer is: When electrons from the wool socks move into the carpet, Sally and her socks gain a negative charge.
Explanation:
When Sally rubs her wool socks on a nylon carpet, the friction between the two materials causes the transfer of electrons. Electrons, which are negatively charged particles, move from the wool socks to the carpet. This results in the wool socks becoming positively charged, as they lose electrons, and the carpet becoming negatively charged, as it gains electrons. The transfer of electrons creates an imbalance of charges, leading to the buildup of static electricity on Sally and her socks.
