A closed compartment containing gas is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is
(A) same everywhere
(B) lower in the front side
(C) lower in the rear side
(D) lower in the upper side

(b) When a enclosed gas is acclerated in the positve
x-direction tine the pressure of the gas decrease along
the positve x-axis and follows the equation
$$\Delta{P}=-\rho{a}{\left.{d}{x}\right.}$$
Where $$\rho$$ is the density and a the acceleration of the
container.
The result will be more pressure on the rear side and
less pressure on the front side.
