Step up transformer increases the magnitude of alternating e.m.f. As the power remains same , current should decrease as per the formula, power= emf x current. So the statement is TRUE.
In uniform circular motion, 1. Speed is constant. 2. Velocity is variable and acts along tangential direction at a point. 3. Centripetal Force and acceleration act along the radius towards the centre if the circular path. 4. Centrifugal force appears to act radially outwards. It is a virtual ,fictitious force, not a real force.
