Vedclass · Answer

(A) physical quantity $(Q)$ is expressed as the product of its numerical value $(n)$ and its unit $(u)$.$Q = n 	imes u$Since the physical quantity remains constant regardless of the system of measurement used,we have:$Q = n_1u_1 = n_2u_2$Therefore,the relationship between the two systems is ${n_1}{u_1} = {n_2}{u_2}$.

If ${u_1}$ and ${u_2}$ are the units selected in two systems of measurement and ${n_1}$ and ${n_2}$ are their respective numerical values,then:
