Vedclass · Answer

(D) $1$. Wave number $(k = 1/\lambda)$ and Rydberg's constant $(R)$ both have dimensions of $[L^{-1}]$.$2$. Stress and Coefficient of elasticity (Young's modulus,Bulk modulus,etc.) both have dimensions of $[M L^{-1} T^{-2}]$.$3$. Coercivity $(H)$ and Magnetisation $(M)$ have different dimensions. Coercivity is the magnetic field strength $(H)$ with dimensions $[A L^{-1}]$,while Magnetisation is magnetic moment per unit volume with dimensions $[A L^{-1}]$. Wait,both are $[A L^{-1}]$. Let us re-evaluate.$4$. Specific heat capacity $(S)$ has dimensions $[L^2 T^{-2} K^{-1}]$ (from $S = Q / (m \Delta T)$),while Latent heat $(L)$ has dimensions $[L^2 T^{-2}]$ (from $L = Q / m$).Since $[L^2 T^{-2} K^{-1}] 
eq [L^2 T^{-2}]$,the pair with different dimensions is Specific heat capacity and Latent heat.

List-$I$	List-$II$
$(A)$ Torque	$(I)$ $kg\,m^{-1}\,s^{-2}$
$(B)$ Energy density	$(II)$ $kg\,m\,s^{-1}$
$(C)$ Pressure gradient	$(III)$ $kg\,m^{-2}\,s^{-2}$
$(D)$ Impulse	$(IV)$ $kg\,m^2\,s^{-2}$

Identify the pair of physical quantities which have different dimensions.
