A particle rotates along a circle of radius R = root2 m with an angular acceleration a = pie/4 rad/s2 starting from rest. Calculate the magnitude of average velocity of the particle over the time it rotates a quarter circle.​

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
