SSY​

Answer 1

Answer:

Hi !!

Explanation:

11) The rate of change of distance is called velocity.

12) Scalar Quantities are those which have magnitude but no direction. Eg: Distance, Speed, Work, Temperature etc.

13) The frequency of oscillation is the number of full oscillations in one time unit, say in a second.

Hope this helps you !!✌️

Answer 2

Explanation:

Rate of change of distance is called speed.

Speed=Distance /Time

2)Physical quantity which possess only magnitude and no direction is called Scalar quantity .Eg-Distance etc

3)The number of vibrations or oscillations undergone bu the pendulum is called Frequency.

Hope this is helpful to you!
