Dimensional formula for torque is

$A$ gas satisfies the relation $P V^{5/3} = K$, where $P$ is pressure, $V$ is volume, and $K$ is a constant. The dimensions of constant $K$ are:

What is the dimension of a physical quantity?

The force of interaction between two atoms is given by $F = \alpha \beta \exp \left( - \frac{x^2}{\alpha kt} \right)$,where $x$ is the distance,$k$ is the Boltzmann constant,$T$ is temperature,and $\alpha$ and $\beta$ are two constants. The dimension of $\beta$ is:

The damping force on an oscillator is directly proportional to the velocity. The units of the constant of proportionality are:

Dimensions of kinetic energy are
