Please answer the following question: Answer the following question given this paragraph: Did you ever rub an inflated balloon against your hair? You can see what happens in Figure below . Friction between the rubber of the balloon and the baby's hair results in electrons from the hair "rubbing off" onto the balloon. That's because rubber attracts electrons more strongly than hair does. After the transfer of electrons, the balloon becomes negatively charged and the hair becomes positively charged. As a result, the individual hairs repel each other and the balloon and the hair attract each other. Electrons are transferred in this way whenever there is friction between materials that differ in their ability to give up or accept electrons. Q: When a balloon is rubbed against hair, they attract each other because of a difference in what? Choices: - Force - Friction - actions - charges A:
A:
charges
