    The answer is 2.628 x 10^-7joules

    Step-by-step explanation:

    Power = work done : time

    Making work done subject of the formula:

    Work done = power dissipated x time

    Work done = 7.3 x 10^-11 x 3600seconds

    3600 seconds is gotten when you convert one hour to seconds.

    Therefore,

    Work done = 2.628 x 10^-7joules

    Note that the value of the current is extraneous and therefore wasn't used.
