    The answer to your question is the letter C. 3 Watts

    Explanation:

    Data

    Power = ?

    Force = 20 N

    Distance = 1.5 m

    time = 10 s

    Formula

    Work = force x distance

    Power = Work/time

    Process

    a) Calculate the Work

    Work = 20 x 1.5

    Work = 30 J

    b) Calculate the Power

    Power = 30J/10s

    Power = 3 Watts

    The units of Power are Watts and the units of Work and energy are Joules.
