Question 1 Report
If the force and the velocity on a system are each reduced simultaneously by half, the power of the system is
Answer Details
Power is the rate at which work is done or energy is transferred. It is given by the formula P = Fv, where P is power, F is force and v is velocity. If both force and velocity are reduced by half, then the power is given by P = (F/2)(v/2) = (1/4)Fv. Therefore, the power of the system is reduced to a quarter of its original value. So, the option closest in meaning is "reduced to a quarter".
