Answer:

1. friction

2. positively ; negatively

3.its not neutral; but a hint is Neutrons are neutral and cannot be moved from nucleus

4.induction

5. it is not conduction but the hint is when charging by conduction, the two objects touch each other.

6.true

7. conduction

8. false because opposites attract

9. A build up of charges on a sock from a dryer

10. repelled , spread further apart

I took the test but I got questions 3 and 5 wrong so you can use the hints to get yours correct.
