A3.0 n force and a 5.0 n force are acting in opposite directions on the same 5.0 kg ball. what is the magnitude of the acceleration of the ball?

Ahollow metal sphere has 6 cm and 11 cm inner and outer radii, respectively. the surface charge density on the inside surface is −100nc/m2. the surface charge density on the exterior surface is:

Heat from the sun reaches earth to a. radiation b. convection c. conduction

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
