Answer:
Explanation:
We have given mass of helium nucleus 
Velocity of helium nucleus 
Momentum of the helium nucleus is given by 
where m is mass and v is velocity
So 
A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a transformer.
<h3>Which device uses electromagnetic induction to transfer electrical energy from one circuit to another?</h3>
- A transformer is an electrical device that transfers energy from one electric circuit to another using the electromagnetic induction principle.
- It is intended to change the AC voltage between the circuits while keeping the current's frequency constant.
- A transformer work on the principle of electromagnetic induction in which flux is linked from primary to secondary.
- Transformers accomplish this without establishing a conductive link between the two circuits. This is made feasible by using Faraday's Law of Induction, which explains how an electric circuit will interact with a magnetic field to produce an electromotive force (EMF).

Answer and Explanation:
We have given the expression 
Dimension of 
Dimension of R which is gas constant
Dimension of temperature T 
And dimension of pressure 
Now combine dimension of 
So the dimension of and dimension P is same so there unit will also be same
From ideal gas equation we know that 
As the both P and has same dimension so they are dimensionally constant
Answer:
For starters, “dark side” is a misnomer. The far side may be constantly facing away from Earth, but as it orbits the Earth it sometimes faces the sun just as the bright side does. Thus the far side is subject to the same day/night temperature extremes as the side facing Earth.
Explanation:
Hello!
When the rock is dropped, it only contains Gravitational Potential Energy, and when it hits the ground, it contains Kinetic Energy.
So:
PE = KE
We can rearrange to solve for velocity. Cancel out mass and solve.
Plug in the givens:
