A body of Specific heat capacity
900 J kg 1k1 initially held at a height of 90m falls to the ground
Neglecting heat loss to the surrounding.
what is the rise in temperature of
of the body on striking the ground?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
