Question

Difine the fundamental quantities

Answer 1

A base unit (also referred to as a fundamentalunit) is a unit adopted for measurement of a base quantity. A base quantity is one of a conventionally chosen subset of physicalquantities, where no quantity in the subset can be expressed in terms of the others.

Answer 2

Answer:

Fundamental quantities:-)

The physical quantities which can be treated as independent of other physical quantities and are not usually defined in terms of other physical quantities are called fundamental quantities. To give a consistent and unambiguous description to all physical quantities, we need a minimum of seven fundamental or base quantities. They are mass, length, time, electric current temperature, luminous intensity and amount of substance.
