Aparticle is moving along the x-axis with velocity v(t) = sin2t. at time t = pi/2 it has position x = 3. find the total distance, s traveled by this particle on the interval 0 < = t < = pi.

In automobile steering wheel is shown what is the ideal mechanical advantage blank? if the ama is eight what is the efficiency of the steering wheel?

It is really hard for me right know

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
