I hate myself. also im crying lol, u don’t care

here’s your free points ig

When objects are charged by they do not need to touch each other. a. friction b. induction c. conduction d. all of these

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
