Correct Answer - Option 2 :
derived quantities
The correct answer is option 2) i.e. derived quantities
CONCEPT:
- A quantity that can be measured is called a physical quantity.
-
Fundamental quantity:
-
Fundamental quantities are those which cannot be expressed or measured in terms of other physical quantities.
-
The SI system has seven fundamental quantities i.e. time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity.
-
Derived quantity:
-
Derived quantities are those which cannot be measured directly.
- They are computed from the combinations of the fundamental quantities.
EXPLANATION:
-
Derived quantities are obtained from fundamental quantities.
- So, they will depend on fundamental quantities.
- Thus, physical quantities which depend on one or more than one fundamental quantities for their measurement are derived quantities.
