Match list - I with list - II and select the correct answer :

Spring constant $$ M^1\,L^2\,T^{-2} $$
Pascal $$ M^0\,L^0\,T^{-1} $$
Hertz $$ M^1\,L^0\,T^{-2} $$
Joule $$ M^1\,L^{-1}\,T^{-2} $$

ANSWER

2,7,9,12


SOLUTION
Spring constant : $$k =\dfrac{F}{x} = \dfrac{MLT^{-2}}{L}=M^1L^0T^{-2}$$, Hence A->3
Pascal: $$P = \dfrac{F}{A} = \dfrac{MLT^{-2}}{L^2} = M^1L^{-1}T^{-2}$$ , Hence B->4
Hertz: $$f =\dfrac{1}{T} = M^0L^0T^{-1}$$, Hence, C->2
Joule: $$W= F \times distance = M^1L^2T^{-2}$$, Hence D->1
