    Answer:

    (a) The power of this pulse is 399.5 W

    (b) The total energy of this pulse is 0.3995 J

    (c) The total charge that flows during the pulse is 8.5 x 10⁻ C

    Explanation:

    Given;

    potential difference developed by the eel, V = 470 V

    current, I = 0.85 A

    time, t = 1 ms = 1 x 10⁻³ s

    (a) the power of this pulse.

    P = IV

    P = 0.85 x 470

    P = 399.5 W

    (b) the total energy of this pulse

    E = Pt

    E = 399.5 x 1 x 10⁻³

    E = 0.3995 J

    (c) the total charge that flows during the pulse

    Q = it

    Q = 0.85 x 1 x 10⁻³

    Q = 8.5 x 10⁻C
