The rate at which velocity is changing at a given instant is described by
-instantaneous acceleration
-average speed
-constant speed
-vector addition

-instantaneous acceleration

Explanation:

As we know that the acceleration is defined as the rate of change in velocity and it is given by the formula

here we know that

= change in velocity

= time interval

now if the time interval is very small then this instantaneous change in velocity with respect to small interval of time is known as instantaneous acceleration.

so correct answer will be

-instantaneous acceleration

spare some change and give it to the poor

explanation:

plz : ((

so easy. just google the electromagnetic waves and it’ll pop up.
