A motor uses an electromagnet to convert electrical energy into mechanical energy.
galben [10]4 years ago

Answer: The correct answer is "motor".

Explanation:

Electric motor: It is the device which converts the electrical energy into the mechanical energy.

When the current is flowing through the wire then there will be magnetic field around the wire.

Both magnetic field and the electric field are applied in the motor. So, there will be electric force and the magnetic force.

Electricity can be used to move magnet. The electric motor uses electricity in this way. It generates the magnetic field with the electric current flowing through the coil. This magnetic field helps in moving the magnet that runs the motor.

Therefore, motor is a device which uses an electromagnet to convert electrical energy into mechanical energy.

Assoli18 [71]

Answer:

The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Explanation: Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. I am so sorry if I get this wrong, I'm in 5th grade! ♥

What is true about the force between charges?
shusha [124]

Answer:

The statements A and D are true

The statements B and C are false

Explanation:

The force between charges can be explained by the Coulomb's Law.

According to Coulomb:

1 - Like charges always repel each other

2- Unlike or opposite charges always attrack each other

3- Force between 2 charges is given by:

F=k\frac{q_1q_2}{r^2}

where F is the force between 2 charges and r is the distance between 2 charges.

We can see that Force F is inversely proportional to the distance r

Which means that when F increase, r decreases and when F decreases, r increases
