Question

Define: i) Fundamental quantities ii) Derived quantities​

Answer 1

Answer:

The Fundamental Quantity is independent Physical Quantity that is not possible to express in other Physical Quanitity. It is used as pillars for other quantities aka Derived Quantities. In Physics, Length, Mass, Time, Electric Current, Thermodynamic Temperature, etc are examples of Fundamental Quantities.

Explanation:

Derived quantities are quantities that are calculated from two or more measurements. They include area, volume, and density. The area of a rectangular surface is calculated as its length multiplied by its width. The volume of a rectangular solid is calculated as the product of its length, width, and height.

Answer 2

Answer:

i-The Fundamental Quantity is independent Physical Quantity that is not possible to express in other Physical Quanitity. It is used as pillars for other quantities aka Derived Quantities. In Physics, Length, Mass, Time, Electric Current, Thermodynamic Temperature, etc are examples of Fundamental Quantities.

ii-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 first group consists of derived quantities, which have proper units.
