GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -Basic physical quantities that do not depend upon other quantities are called fundamental physical quantities. There are seven fundamental quantities-length, mass, temperature, time, electric current, luminous intensity and amount of substance. Was this answer helpful?

Detailed explanation-3: -Physical quantities that are derived from one or more fundamental physical quantities are called derived physical quantities. Examples: area, volume, speed, density, etc. Was this answer helpful?

Detailed explanation-4: -The present SI has seven base quantities: time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

Detailed explanation-5: -Derived quantities are physical quantities derived from combinations of base quantities through multiplication.
