The meter that is used to measure the distance moved by the vehicle is known as:
Detailed Explanation:

Ammeter measures electric current, Speedometer measures instantaneous speed, and Chronometer measures precise time.
Which of the following is not a vector quantity?
Detailed Explanation:
A vector quantity possesses both magnitude and direction, whereas a scalar quantity has only magnitude.
- Speed is a Scalar: It measures only how fast an object moves, without any directional information (e.g., 50 km/h).
- Velocity, Displacement, and Torque are Vectors: Velocity is speed with direction; displacement is change in position with direction; torque is rotational force with directional sense.
- Therefore, speed is the only scalar among the options, making Option 4 the correct answer.
