Question

1. a balloon that has been charged can hover over your head without actually touching it and cause your hair to stand up. what type of electron transfer makes the hair standing up possible?

friction
induction
electric fields
conduction

Explanation:

When a charged balloon hovers over the head (without touching), it causes a separation of charges in the hair (like charges repel). This is the process of induction. Friction involves direct rubbing (not the case here). Electric fields are a concept related to the space around charges but not the type of electron transfer. Conduction requires direct contact (which is not happening as the balloon doesn't touch the hair).

Answer:

induction
