Uniform solid sphere of radius r rotates about a diameter with an angular speed 536 radians/second. the sphere then collapses under the action of internal forces to a final radius r/2. what is the final angular speed of the sphere in radians/second?

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
