Question

Name three derived physical quantities

Answer 1

1. Derived quantities are those that depend on other physical quantity .
2. They can be mentioned in terms of fundamental quantities.
3. Examples include area, volume and density which are derived from basic physical quantities length, breadth, height ,mass and volume respectively
4. Area is given by formula
   $$\begin{gathered} \mathrm{length}\times \mathrm{length},\mathrm{usually}\mathrm{expressed}\mathrm{in}{\mathrm{m}}^2. \\ \mathrm{volume}=\mathrm{length}\times \mathrm{breadth}\times \mathrm{height};\mathrm{usually}\mathrm{expressed}\mathrm{in}{\mathrm{m}}^3. \\ \mathrm{similarly}\mathrm{density}=\frac{\mathrm{mass}}{\mathrm{volume}};\mathrm{unit}\mathrm{is}\mathrm{kg}/{\mathrm{m}}^3. \end{gathered}$$
