D. 5.85 m

Given :

A wrecking ball of mass 500 kg hangs form a crane by a cable of length 25 m

this wrecking ball is released from an angle of 40 degrees.

To Find :

The height  from the lowest point of the arc.

Solution :

From the attached image we have to find the value of  h.

So,

Hence, this is the required solution.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
