    A speedometer measure the instantaneous speed of a vehicle.

    Answer: Option C

    Explanation:

    A speedometer is a gauge used in vehicles to measure their instantaneous speed. It is basically invented to measure the instantaneous speed of the vehicle such as cars. This is simply the ratio of the distance covered in a unit time.

    Its cable gets powered by driveshaft and turned. The cable rotates the magnet at the same speed in the Speed Cup. The hair spring becomes tighter and limits the speed pan to prevent it from turning too much. As the speed cup runs, the arrow raises the dial up to show the vehicle speed.
