An Ohmic material is one in which its resistance does not depend on the voltage across it or the current within it. In that case, the resistance does NOT depend on:

A concave lens is also called a diverging lens.

If one light bulb is removed from a parallel circuit with three bulbs, the brightness of the other bulbs will decrease.

If two objects collide and one is initially at rest, is it possible for both to be at rest after the collision? Is it possible for one to be at rest after the collision.

Big commercial airplanes are sometimes pushed to an area by a tractor. A 1800-kg tractor exerts a force of 1.75x 104 N backward on the pavement, and the system experiences forces resisting motion that total 2400 N.
