Define supplementary quantities,derived quantities and fundamental quantities
Answers
Answer:
Supplementary units are the dimensionless units that are used along with the base units to form derived units in the International system. Supplementary quantities are geometrical quantities of circle and sphere.
Derived quantities are those that may be expressed in terms of base or derived quan- tities by means of the mathematical symbols of multiplication and division only (no addition or subtraction or any other sign).
The quantities that are independent of other quantities are called fundamental quantities. The units that are used to measure these fundamental quantities are called fundamental units.

A derived quantity is one that is derived from a formal equation that involves all of the seven fundamental quantities: kilogramme, metre, second, ampere, kelvin, mole, and candela. Area (square metres), speed (metres per second), and frequency are examples of derived quantities (hertz).Geometrical quantities of circle and sphere are supplementary quantities.
Supplementary units are those that aren't yet graded as either base or derived.Physical quantities are divided into seven basic and two supplementary categories.As the name implies, supplementary physical quantity is a physical quantity that is used for calculation (on a secondary level). Plane angle and solid angle are two supplementary units of two purely" geometrical physical quantities. and their units are radian (rad) and steradian (Sr) respectively.
Note:Fundamental quantities are the quantities which cannot be derived from any other quantity of nature they are the most basic quantities; the quantities made by using the fundamental quantities are known as the derived quantities; and the quantities which don’t come under any of these two quantities are known as supplementary quantities i.e they are not the basic quantities as well as they cannot be derived.
