A research Van de Graaff generator has a 3.90 m diameter metal sphere with a charge of 1.08 mC on it.

(b) At what distance from its center is the potential 2.00 MV?

(c) An oxygen atom with three missing electrons is released near the surface of the Van de Graaff generator. What is its kinetic energy in MeV at the distance determined in part (b)?

Calculate the volume of this regular solid. what is the volume of the cone? round your answer to the nearest hundredth

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

If you let go of the notebook after lifting it, will it move? how?
