Physics Static Elctricity 0.0 / 5 ? ScienceElectricityGCSEEdexcel Created by: TomMcCarthyCreated on: 17-11-15 21:01 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. 10 of 10
