Which of these describes an effect of static electricity?

• Neutrons are neutral and located at the center of an atom

• A girl shocks her brother after walking across a rug.

• Electrons carry a negative charge

• A light bulb turns on when a closed circuit is created

When Ella took two socks out of the dyer, they stuck together. Why?

• Because the socks became neutral in the dyer

• Because neither sock is an insulator

• Because the socks became charged in the dyer

• Because the socks became conductors
