Answers

1. C. be halved

The magnetic force is strongest at the poles. These force gets weaker as you move far away from the magnet.

2. D. Albert Einstein

The is the scientist who made many discoveries about light. Studying light has brought many technologies in the modern physics.

3. C. Michael Faraday

Michael Faraday is the sole inventor of the electrical generator.

4. A. photon

Light moves small packs called pack. these packets can be termed as packages.

5. B. field

Magnetic field is the region where the strength is experienced. This region has fields that points north to south.

6. Series

there are 2 types of circuits; series and parallel. For parallel circuits when one bulb goes off the rest remain on but for the series circuit, when one bulb goes off the rest goes off too.

7. C. conduction

Conduction is the method of charging a body where the changing body makes contact with the body been changed. The body been charged acquires the same charge as the charging body.

8. B. induction

Induction is the method of charging a body where the changing body makes no contact with the body been charged. The body been charged acquires the opposite as charge as the charging body.

9. E. friction

Friction is a method of charging a body by rubbing. The two bodies acquire opposite charges.

10.A. directly

When an object is placed between two charged bodies, it experiences a force due to interaction of the fields from the two charges. The magnitude of this force depend with the amount of charge of the individual bodies.

11. .Inversely

When an object is placed between two charged bodies, it experiences a force due to interaction of the fields from the two charges. The magnitude of this force depend with the amount of charge of the individual bodies.

12. B. repel

The law of charges states that like charges repel while unlike charges attract.

13. A. attract

The law of charges states that like charges repel while unlike charges attract.

14. E. amperes

Current is the rate of flow of electric charges. These rate of flow of charges is amperes. The S.I units of current is Amperes.

15. C. current

Current is the rate of flow of electric charges passing a given point. These rate of flow of charges is amperes. The S.I units of current is Amperes.

16. A. resistance

Resistance is the opposition of electric current to flow in a conductor. This opposition causes the wires to heat up causing the heating effects.

17. B. Maxwell

Maxwell discovered that when an electric current is flowing through a conductor, it has an effect on magnetic compass.His law is called  the Maxwell's swimming rule.

18. D. induction

The conventional current flows from positive side of a battery to the negative side. No current flows in an open circuit.  In an induction circuit the electric current flows from negative to positive.

19. D. less

Thick wires has many free electrons that act as change carriers. This makes it a better conductor hence less resistance.

20. C. current

Thin wires have few free electrons. This electrons are the one that carry the current from one end to the other. The electromagnetic force in these wires is converted to current.
