According to Newton, the viscous force acting between liquid layers of area A and velocity gradient $\Delta v/\Delta z$ is given by $F = - \eta A\frac{{{\rm{\Delta }}v}}{{{\rm{\Delta }}x}}$ where $\eta$ is constant called coefficient of viscosity. The dimensions of $\eta$ are

Force constant has the same dimensions as

Force constant has the same dimensions as

The ionization energy of hydrogen is 13.6 eV. Express this energy in joules per mole using the following conversions: 1 eV = $1.602 imes 10^{-19}$ J and Avogadro's number = $6.022 imes 10^{23}$ $mol^{-1}$.

What is the dimensional formula of $\frac{{{\rm{planck}}\,{\rm{s\;constant}}}}{{{\rm{linear\;momentum}}}}?$
