The correct choice is

C) a powerful magnet.

we know that a current carrying wire creates magnetic field around it. inside this magnetic field, when a magnet comes, the magnet experience magnetic force. This same thing happen in motor which is known as motor effect.

the electric current running through coil creates magnetic field which exerts the force on the permanent magnet.

A ball is suspended by a lightweight string, as shown in the figure above.
Irina18 [472]

<u>Answer </u>

A. 1 and 2

<u>Explanation </u>

At point 1 we have the highest potential energy and the kinetic energy is zero.

At 2 the potential energy is minimum and the kinetic energy is maximum.

The law of conservation of energy says that energy cannot be created nor destroyed. So, the change in P.E = Change in K.E.

P.E = height × gravity × mass. The height referred here is the perpendicular height. Gravity and mass are constant in this case.

From the diagram it can be seen clearly that the vertical height from 2 to 1 is much greater than from 4 to 3.

This shows that the change in P.E is greater between 1 and 2 and so is kinetic energy.
