The production of an electric current by a changing magnetic field is known as electromagnetic induction.
The phenomenon when the current is produced due to changing magnetic field is given by Faraday.
And this phenomenon is called the electro-magnetic induction or magnetic induction since the electricity is generated due to the fluctuations or variance in the magnetic field.

Your car is performing a transformation of energy of:
Chemical energy to Mechanical energy
The chemical is the gasoline which is then converted to fire as the car runs thus creating the movement of the car which is mechanical energy.
Answer:
Muscle size and training specifiicty
Explanation:
It depends on all other factors such as anatomy and psychology, muscle fiber recruitment, motor pattern development and muscle memory but to increase modifiable strength, size plays no big role.
PART A)
Equivalent resistance in parallel is given as

now we have


PART B)
since potential difference across all resistance will remain same as all are in parallel
so here we can use ohm's law

As we know i = 7 A current flows through 15 ohm resistance

PART C)
Similarly ohm's law for 20 ohm resistance we can say



Answer:
<h2> B. Components</h2>
Explanation:
Splitting vectors into components makes it easier to perform operations on them, typically categorizing vectors into horizontal and vertical components which are the two components makes it very easy to perform operations, since they are similar terms and operations cab be done easily
