Answer 10

It states that Opposite charges attract each other

Question 11

Law of repulsion

Answer 11

It states that like charges repel each other

Question 12

Conductivity

Answer 12

The ability of a material to allow electrons to move freely within it

Question 13

Insulator

Answer 13

A substance which does not allow electrons to move within it

Question 14

Conductor

Answer 14

A substance that allows electrons to move freely within it.

Question 15

Conduction

Answer 15

The movement of electrons through a substance.

Question 16

Electroscope

Answer 16

An instrument that can detect static electric charges

Question 17

Electrostatics

Answer 17

the study of static electric charges

Question 18

Positive charge

Answer 18

A charge that exists in a substance that has fewer electrons than protons

Question 19

Negative charge

Answer 19

A charge that exists in a substance that has more electrons than protons

Question 20

Charging by contact

Answer 20

A form of charging in which a charged object touches a neutral object and transfers electrons to it

Question 21

Charging by induction

Answer 21

A form of charging in which a charged object is used to induce the charge in a neutral object and then the newly charged object is grounded so it retains the charge. It requires no physical touch between the objects.

Question 22

Induction

Answer 22

The movement of electrons within an object caused by a nearby charged object, without direct contact between the objects.

Question 23

Grounding

Answer 23

The process of connecting a charged object to earths surface

Question 24

Electrical discharge

Answer 24

The process by which electric charges are transferred very quickly
