Answer

C

Question 32

Why does the child's hair stick up?

Accepted Answer

He gained a charge from the slide, and since he's not grounded, his hairs have the same charge so they repel one another

Answer

The boy is grounded since he's at the bottom of the slide

Answer

He gained a charge from the slide, and since he's not grounded, his hairs have opposite charges so they repel one another

Answer

When hair is neutral, some have a positive side and some have negative side, so they will attract to each other, making it stand up

Question 33

Accepted Answer

This is charging by contact - electrons want to even out

Answer

This is grounding - electrons want to even out

Answer

This is charging by contact - electrons go to the larger object

Answer

This is charging by contact - electrons go from the object with less e- affinity to more e- affinity.
