Test: Dimensional homogeneity - Question 9
Save

The principle of dimensional homogeneity serves the following useful concepts
(i) It helps to check whether an equation of any physical phenomenon is dimensionally homogenous or not
(ii) It helps to determine the dimensions of a physical quantity
(iii) It helps to convert the units from one system to another
Identify the correct statements

Detailed Solution: Question 9

It serves all the aspects.

Test: Dimensional homogeneity - Question 10
Save

How is dimensional homogeneity related with fundamental units of measurements?

Detailed Solution: Question 10

This implies that the length dimension can be added to subtract from only a length dimension.
