Vedclass · Answer

(A) The dimensional formulas are calculated as follows:$(a)$ Wave vector $(k = 2\pi / \lambda)$: The dimension is $[L^{-1}]$, which corresponds to $M^0L^{-1}T^0$ $(iii)$.$(b)$ Linear mass density $(\mu = 	ext{mass} / 	ext{length})$: The dimension is $[ML^{-1}]$, which corresponds to $M^1L^{-1}T^0$ $(iv)$.$(c)$ Intensity of a wave $(I = 	ext{Power} / 	ext{Area})$: Power is $ML^2T^{-3}$, so $I = (ML^2T^{-3}) / L^2 = MT^{-3}$, which corresponds to $M^1L^0T^{-3}$ $(i)$.$(d)$ Volume elasticity coefficient $(B = 	ext{Stress} / 	ext{Strain})$: Stress is $ML^{-1}T^{-2}$ and strain is dimensionless, so $B$ is $M^1L^{-1}T^{-2}$ $(ii)$.Therefore, the correct matching is $(a-iii, b-iv, c-i, d-ii)$.
