Physics - Unit & Dimension Question with Solution | TestHub

Reynolds number and coefficient of friction are both dimensionless;
curie (decays per unit time) and frequency are both $\left[T^{-1}\right]$;
latent heat and gravitational potential are both $\left[L^2{T}^{-2}\right]$ (energy per unit mass).
Planck's constant
$\left[M{L}^2{T}^{-1}\right]\ne$ torque
$\left[M{L}^2{T}^{-2}\right]$.
