Match the LIST-I with LIST-II
Choose the correct answer from the options given befow:
Spring constant:
$$F=kx\Rightarrow k=\frac{F}{x}$$
$$[k]=\frac{MLT^{-2}}{L}=[MT^{-2}]$$
So, (A) matches with (II)
Thermal conductivity:
From Fourier’s law:
$$\frac{Q}{t}=kA\frac{\Delta T}{L}$$
$$k=\frac{Q}{t}\cdot\frac{L}{A\Delta T}$$
$$[Q]=ML^2T^{-2}$$
$$[k]=\frac{ML^2T^{-2}}{T}\cdot\frac{L}{L^2\cdot K}=[MLT^{-3}K^{-1}]$$
So, (B) matches with (IV)
Boltzmann constant:
$$E=k_BT$$
$$\left[K_B\right]=\frac{E}{T}=\frac{ML^2T^{-2}}{K}=[ML^2T^{-2}K^{-1}]$$
So, (C) matches with (I)
Inductive reactance:
$$X_L=\omega LXL=ωL$$
$$[X_L]=[\text{resistance}]=[ML^2T^{-3}A^{-2}]$$
So, (D) matches with (III)
Final matching:
(A)−(II), (B)−(IV), (C)−(I), (D)−(III)
