5.
describe what an insulator does:
a)
an insulator doesn't stop current.
b)
an insulator does stop current.

6.
what are Newton's 3 laws
a)
he was never part of the law, though.
b)
1) An object at rest will remain at rest unless acted on by an unbalanced force.
2) Acceleration is produced when a force acts on a mass. The greater the mass the greater the amount of force needed.
3) For every action there is an equal and opposite reaction.
