Answer 2

Answer:

Here you go!!

Explanation:

1. Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant

2. Extreme position, the maximum distance of the bob from its mean position.

3. The SI unit of speed and velocity is the ratio of two — the meter per second. Speed and velocity are both measured using the same units.

4.Odometer reading measures the distance travelled by a vehicle. SI unit of distance is metre(m).
