Answer 2

Answer:

Fundamental quantities are those physical quantities that cannot be expressed in terms other quantities. It is independent on its own. For example: Mass, Length, time, temperature, electric current.

In physics, there are seven fundamental physical quantities that are measured in base or physical fundamental units: length, mass, time, electric current temperature, amount of substance, and luminous intensity. ... These are called derived units.
