<h3><u>Answer;</u></h3>
1st drop; Motor
2nd drop; Electricity
A device that uses electricity and magnetism to create motion is called a <u>motor</u>. In a reverse process, a device that uses motion and magnesium can be used to create <u>electricity</u>.
<h3><u>Explanation</u>;</h3>
- <em><u>Motors are device which use electricity and magnetism to create motion.</u></em> They pass alternating current through opposing pairs of magnets to create a rotating magnetic field which creates a magnetic field in the rotor of a motor, making it to spin around.
- <em><u>Electric motors work in a reverse process by using motion and magnetism to generate electricity. </u></em>When a coil or loops of wire are exposed to a changing magnetic field, an electrical current arises or is induced.
Answer:
Mass of astronaut will be 119.7674 kg
Explanation:
We have given mass of the chair
When there is chair alone then time period of osculation
Now when astronaut sit on the chair then total mass
Now with astronaut time period is
For spring time period is given by
So
Squaring both side
Mass of astronaut will be 119.7674 kg
People are going to tell you about heating or cooling the gas, but
there's only one way to change the volume of a gas: Put it into a
different container !
A gas always expands to fill whatever you keep it in ... doesn't matter
how warm or cold it is. So the only way to make it change its volume
is to put it into a larger or smaller jar.
Sound waves the force of said sound wave would knock you backwards
yes it's true................
