    The energy which is produced by a battery is 101.1 kJ.

    Explanation:

    The expression for the energy in terms of voltage, current and time is as follows;

    E=VIt

    Here, V is the voltage, I is the current and t is the time.

    It is given in the problem that a battery can provide a current of 1.80 A at 2.60 V for 6.00 hr.

    Calculate the energy of the battery.

    E=VIt

    Convert time from hour int seconds.

    t=6 hr

    t = (6) (60) (60)

    t=21600 s

    Put I = 1.80 A, V = 2.60 V and t = 21600 s in the expression of energy.

    E = (2.60) (1.80) (21600)

    E = 101.1 kJ

    Therefore, the energy which is produced by a battery is 101.1 kJ.
