    Answer:

    The electric charge passes is 15.2 C.

    Explanation:

    The electric current is drawn from a battery = 16 A

    The diameter of copper wire is = 5 mm

    The length of copper wire is = 1.52 m

    Running time of starter motor before the start of car engine = 0.95 s

    Therefore, the current 16 A passes through the copper wire for 0.95 seconds.

    The calculation of electric charge passes:

    Charge = i \times t \\

    = 16 \times 0.95 \\

    = 15.2 C
