Which of the following is a derived unit?

a. meter (m)

b. second (s)

c. kilogram (kg)

d. mass density (kg/m^3)

Option D

Explanation:

From the options given above, only Density (kg/m^3) is a derived unit and the rest are fundamental unit.

A derived unit is obtained by combining two or more fundamental units together. For Density, we can obtain the unit as follow:

Density = Mass / volume

The unit of mass is Kg and that of volume is m^3

We can thus write the unit of destiny as:

Density = > Kg/m^3
