Correct Answer
A. The path in which electricity travelsExplanation
A circuit refers to the path in which electricity travels. It is a closed loop that allows the flow of electric current from a power source to various components and back to the source. This path is typically formed by connecting wires and electrical devices in a specific arrangement. By completing the circuit, electricity can flow continuously, enabling the functioning of electrical systems and devices.Rate this question:

What is a force
- A.
The push or pull that makes something move
- B.
The path that electricity travels through
- C.
An event that makes something happen
- D.
A heat source
Correct Answer
A. The push or pull that makes something moveExplanation
A force is defined as a push or pull that causes an object to move or change its motion. It is the interaction between two objects or between an object and its surroundings that results in a change in velocity or acceleration. This definition accurately describes the concept of force and distinguishes it from other options such as the path of electricity, an event, or a heat source, which are unrelated to the concept of force.Rate this question:

A person, thing or event that makes something happen
Correct Answer
D. A person, thing or event that makes something happenExplanation
The term "cause" refers to a person, thing, or event that is responsible for making something happen. It implies a direct or indirect influence that leads to a particular outcome or effect. This definition aligns with the idea that a cause is not limited to physical forces or movements but can also encompass various factors that contribute to the occurrence of an event or the creation of a situation.Rate this question:

A force between the earth and objects
- C.
A place on a magnet
- D.
A form of energy
Correct Answer
A. An event that is caused by an earlier eventExplanation
The correct answer is "An event that is caused by an earlier event." This definition of "effect" refers to something that happens as a result or consequence of a previous action or event. It implies a cause-and-effect relationship, where one event leads to another.Rate this question:

Cause
Correct Answer
D. CauseExplanation
A cause is something that brings about or leads to an effect or result. It is the reason or explanation behind an action, event, or phenomenon. It is the factor or influence that initiates or triggers a particular outcome. In this context, a cause is the most appropriate term to describe a person, thing, or event that makes something happen.Rate this question:

Correct Answer
B. An effectExplanation
An event that is caused by an earlier event is called an effect. This term refers to the result or consequence of a preceding action or cause. It implies a cause-and-effect relationship, where the earlier event is responsible for bringing about the subsequent event. The term "force" refers to a push or pull that can cause an object to accelerate or deform. "Gravity" is a natural force that causes objects to be attracted to one another. "To repel" refers to the action of pushing or forcing something away.Rate this question:

The push or pull that makes something move is called
- A.
Gravity
- B.
Force
- C.
Effect
- D.
Cause
Correct Answer
B. ForceExplanation
Force is the correct answer because it refers to the push or pull that causes an object to move or change its motion. Gravity is a force, but it specifically refers to the force that attracts objects towards each other. Effect and cause are not accurate terms to describe the push or pull that makes something move.Rate this question:

- A.
Poles
- B.
Pools
- C.
Circuits
- D.
Forces
Correct Answer
A. PolesExplanation
Magnets have two ends that are called "poles". These poles are known as the north pole and the south pole. The north pole of one magnet attracts the south pole of another magnet, while like poles repel each other. This phenomenon is due to the magnetic field generated by the alignment of the atoms within the magnet. The concept of poles is fundamental in understanding the behavior and interactions of magnets.Rate this question:

What are the two poles of the magnets (choose two)
- A.
North
- B.
Down
- C.
East
- D.
West
- E.
South
Correct Answer(s)
A. North
E. SouthExplanation
The two poles of a magnet are the North pole and the South pole. These poles have opposite magnetic properties and attract each other. The North pole of one magnet will attract the South pole of another magnet, while the North pole of one magnet will repel the North pole of another magnet. Similarly, the South pole of one magnet will attract the North pole of another magnet, while the South pole of one magnet will repel the South pole of another magnet. Therefore, the correct answer is North and South.Rate this question:
-

When a north pole of one magnet is placed next to a south pole of another magnet the magnets will
- A.
Repel each other
- B.
Not move
- C.
Attract each other
- D.
Stand up straight
Correct Answer
C. Attract each otherExplanation
When a north pole of one magnet is placed next to a south pole of another magnet, they will attract each other. This is because opposite poles attract each other according to the laws of magnetism. The north pole of one magnet has a magnetic field that is attracted to the south pole of the other magnet, resulting in an attractive force between them.Rate this question:
-

When the pole of one magnet is placed next to the same pole of another magnet, what will happen?
- A.
They will repel
- B.
They will attract
- C.
Nothing will happen
- D.
They will break
Correct Answer
A. They will repelExplanation
When the pole of one magnet is placed next to the same pole of another magnet, they will repel each other. This is because like poles of magnets have the same magnetic polarity, causing a force of repulsion between them. The magnetic field lines of both magnets will push against each other, resulting in the magnets moving away from each other.Rate this question:

What is a conductor of electricity
- A.
Something that electricity can't move through
- B.
Something that makes electricity stop
- C.
Something that electricity can move through
- D.
Something that makes electricity repel magnets
Correct Answer
C. Something that electricity can move throughExplanation
A conductor of electricity is a material or substance that allows the flow of electric charge or current through it. It contains free electrons that are able to move easily, enabling the transfer of electrical energy. Conductors typically have low resistance to the flow of electricity, making them suitable for transmitting and distributing electrical power.Rate this question:

What is a source of electricity
- A.
The sun
- B.
The wind
- C.
Water
- D.
A battery
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
The correct answer is "all of the above" because all of the options listed are sources of electricity. The sun can generate electricity through solar power, the wind can generate electricity through wind turbines, water can generate electricity through hydroelectric power, and a battery can store and provide electricity. Therefore, all of these options are valid sources of electricity.Rate this question:
-
- 25.
What would happen if electricity went into water.
- A.
The water would freeze
- B.
Nothing
- C.
Electricity would flow through it because water is a conductor
- D.
The water would turn black.
Correct Answer
C. Electricity would flow through it because water is a conductorExplanation
Electricity would flow through water because it is a conductor. Conductors are materials that allow the flow of electric current. Water, although not a great conductor, still contains ions and impurities that can conduct electricity to some extent. When electricity is passed through water, the ions in the water allow the current to flow. This can be dangerous as it can cause electric shock or damage electrical equipment.Rate this question:
