1 marks for each

Answer 1

Answer:

Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future. ..

The time period is the time taken by a complete cycle of the wave to pass a point, Frequency is the number of complete cycle of waves passing a point in unit time.

Oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. The term vibration is precisely used to describe mechanical oscillation.

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

to reduce the speed of , slow down.
