In rectilinear motion, motion depends on a?​

The object moving in a straight path is called linear or rectilinear motion.

An object is said to be in rectilinear motion if it changes its position,along a straight line path.

Explanation:

example: A car moving in a straight road.

A jet moving straight in air

the answer would be 32*f

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.
