Answer & Solution
Correct Answer
(B) \((A)-(IV), (B)-(III), (C)-(I), (D)-(II)\)
Step-by-step Solution
Detailed explanation
\((A)\) Surface Tension \(=\frac{ F }{\ell}=\frac{ MLT ^{-2}}{ L }= ML ^{-1} T ^{-2}\)
\(= Kgs ^{-2}( IV )\)
\((B)\) Pressure \(=\frac{ F }{ A }=\frac{ MLT ^{-2}}{ L ^2}\)
\(= kg m ^{-1} s ^{-2}\) (III)
\((C)\) Viscosity \(==\frac{ F }{ A \left(\frac{ dV }{ dz }\right)}=\frac{ MLT ^{-2}}{ L ^2\left(\frac{ LT ^{-1}}{ L }\right)}\)
\(= ML ^{-1} T ^{-1}= kg m ^{-1} s ^{-1}\) (I)
\((D)\) Impulse \(=\int Fdt = MLT ^{-2} \times T\)
\(= MLT ^{-1}= Kgms ^{-1}( II )\)
