The dimensional formula for angular momentum is

The de-Broglie wavelength associated with a particle of mass $m$ and energy $E$ is $h / \sqrt{2 m E}$. The dimensional formula for Planck's constant $h$ is:

The dimensions of resistance are the same as those of $......$ where $h$ is the Planck's constant and $e$ is the charge.

The dimension of the ratio of angular momentum to linear momentum is

Turpentine oil is flowing through a tube of length $l$ and radius $r$. The pressure difference between the two ends of the tube is $P$. The viscosity of oil is given by $\eta = \frac{P(r^2 - x^2)}{4vl}$,where $v$ is the velocity of oil at a distance $x$ from the axis of the tube. The dimensions of $\eta$ are
