The rope of a swing is 3.00 m long. Calculate the angle from the vertical at which a 91.0 kg man must begin to swing in order to have the same KE at the bottom as a 1530 kg car moving at 1.29 m/s (2.89 mph).

What is the measure of a change in an objects velocity?

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

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
