Answer 1

The best explanation for why Isabella's hair becomes attracted to the balloon after she rubs it on her hair is:

Rubbing the balloon along her hair moves electrons from her hair to the balloon.

When the balloon is rubbed against her hair, electrons are transferred from the hair to the balloon. This gives the balloon a negative charge (due to the excess electrons) and leaves the hair with a positive charge (due to the loss of electrons). The opposite charges attract, which is why her hair is drawn to the balloon.
