Question

If unit of lenght is micrometre and unit of time is microsecond,then unit of velocity will be

Answer 1

Original unit of Velocity is m/s

To convert into demanded unit Numerical Calculation..

Unit of length is micrometre not metre.
Unit of Time is microsecond not second.

Then Unit of Velocity would be -

micrometre/microsecond

Answer 2

Explanation:

It is given that,

The unit of length ( distance )is in micrometer, d = 10⁻⁶ m

The unit of time is in microsecond, t = 10⁻⁶ second

The rate of change of displacement is called the velocity of an object. Mathematically, it can be written as :

$v=\dfrac{d}{t}$

Where

d is displacement

t is time

So, it is clear from above formula that the unit of velocity is equal to micrometer per microsecond or meter per second (m/s)
