# Match List I with II and select the correct answer:List-IList-IIA.Spring constant1. ${ M }^{ 1 }{ L }^{ 2 }{ T }^{ -2 }$B.pascal2. ${ M }^{ 0 }{ L }^{ 0 }{ T }^{ -1 }$C.hertz3. ${ M }^{ 1 }{ L }^{ 0 }{ T }^{ -2 }$D.joule 4.${ M }^{ 1 }{ L }^{ -1 }{ T }^{ -2 }$

A-3, B-4, C-2, D-1

##### SOLUTION
Spring constant dimensions will be $K=\dfrac{F}{X}=\dfrac{MLT^{-2}}{L}=ML^0T^{-2}$

Pascal is unit of pressure $\dfrac{F}{A}=\dfrac{MLT^{-2}}{L^2}=ML^{-1}T^{-2}$

Hertz is frequency $=\dfrac{1}{t}=T^{-1}$

Joule is unit of energy so dimension is $ML^2T^{-2}$

You're just one step away
