What are fundamental units and derived units?

Distinguish between fundamental and derived units.

How many fundamental quantities are there is SI units?

These are the fundamental units of neural tissues:

If force |F| , velocity |v| and time |T| are taken as to fundamental units then the dimensions of mass are

If force (F) , velocity (V) and time(T) are taken as fundamental units , then the dimensions of mass are:

Name the supplementary units converted into derived units.

In a system of units, if force (F), acceleration (a) and time (T) are taken as fundamental units then the dimensional formula of energy is ...............
