Answer:
A
Explanation:
Electromagnet: It is a temporary magnet. It consists of wrapping coils around iron core and the power source. When the current passes through the coils around the iron core then it will get magnetized. The domains of the electromagnet gets aligned.
As long as the current passes through it, it will get magnetized. It will loose its magnetism easily when the power is switched off.
In the electromagnet, the strength of the magnetism can be increased or decreased. The poles of the electromagnet are not fixed.
Main answer- the velocity of 2.2kg ball is 12.566m/s
supporting answer- In circular motion the velocity is termed as angular velocity
Angular velocity represents the rate of variation of an object's position angle with respect to time.
W =theta/ time
W = length of the arc/ radius of circle × time
body of the answer-2πr/r×t =2π/t
2×π/ 0.5 = 12.566 m/s
final answer- hence the velocity of ball is revolving is 12.566 m/s
