HideShow resource information
What is an atom made of?
Electrons and a nucleus that contains protons and neutrons.
1 of 10
What is static electricity caused by?
Friction caused by two insulators being rubbed together.
2 of 10
What do like charges do?
Repel.
3 of 10
What do opposite charges do?
Attract.
4 of 10
How does an object become positively induced?
Negative charges are transferred away from the object so it has more positive than negative charges.
5 of 10
Why can a negatively induced balloon stick to a wall?
Its negative charges are attracted to the positive charges in the wall.
6 of 10
What can happen when you are charged and you touch a conductor?
A spark.
7 of 10
Why do paint sprayers use electrostatic charges?
The sprayer gives all of the droplets the same charge so they repel away from each other and leave an even spray
8 of 10
Why can filling a fuel tank be dangerous?
Static can build up and cause a spark which could lead to an explosion.
9 of 10
How can these refueling explosions be prevented?
Earth the object by connecting a conducting wire to the ground to allow the charges to flow without causing an explosion.
