Positive charge is distributed uniformly throughout a non-conducting sphere. The highest electric potential occurs: A. Far from the sphere B. Just outside the surface C. At the surface D. Halfway between the center and surface E. At the center

A fellow student with a mathematical bent tells you that the wave function of a traveling wave on a thin rope is y (x, t) = 2.30mmcos[ (6.98rad/m) x + (742 rad/s) t]. Being more practical, you measure the rope to have a length of 1.

What type of wave can be seen by the human eye

Why is it called Newton's law of universal gravitation?

You push a shopping cart filled with groceries (total mass = 20 kg) by applying a force to the cart 30° from the horizontal. if the force you apply has a magnitude of 86 n, what is the cart's acceleration? assume negligible friction.

Two objects are made of the same material, but they have different masses and temperatures. If the objects are brought into thermal contact, which one will have the greater temperature change

A ball strikes a wall. It exerts a force of 10 N to the left against the wall and bounces off. What force does the wall exert on the ball?
