A ball of mass 0.616 kg moving east (+x direction) with a speed of 3.90 m/s collides head-on with a 0.308 kg ball at rest. Assume that the collision is perfectly elastic. What is the speed of the .616kg ball after the collision? What is the .308kg ball after the collision?

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
