Answer 1

$\huge\boxed{ \fcolorbox{red}{yellow}{Derived Units:-}}$

•Derived Units are derived from Fundamental Units.

•In chemistry, a derived unit is an SI unit of measurement derived as a product of one or more of the seven base units.

$\huge\boxed{ \fcolorbox{red}{yellow}{Examples:-}}$

•For example, meter is a fundamental unit of length and second is a fundamental unit of time. However, meter per second (ms-1) is a derived unit of velocity.

•For example, the SI unit of force is the derived unit newton (N): One newton is equal to 1 m·kg/s2.

Units of physical quantities can be expressed in terms of fundamental units and such units are called derived units.

So speed is the derivative of distance and time.
