1.	Consider a gas with density P and overset(-)(c) as the root mean square velocity of its molecules contained in a volume. If the system moves as a whole with velocity , then the pressure exerted by the gas is
Answer» `(1)/(3)rho((OVERSET(-)(c))^(2))` `(1)/(3)rho(overset(-)(c)+v)^(2)` `(1)/(3)rho(overset(-)(c)-v)^(2)` `(1)/(3)rho((overset(-)(c ))^(2)-V)^(2)` ANSWER :A
