6. The mean free path of a gas molecule is:(A) the shortest dimension of the containing vessel(B) the cube root of the volume of the containing vessel(C) approximately the diameter of a molecule(D) average distance between adjacent molecules(E) average distance a molecule travels between intermolecular collisions

8. Consider Gauss's law: \( \oint_{S} \vec{E} \cdot d\vec{A} = q/\epsilon_0 \). (A) \( \vec{E} \) must be the electric field due to the enclosed charge (B) if \( q = 0 \) then \( \vec{E} = 0 \) everywhere on the Gaussian surface (C) if the charge inside consists of an electric dipole, then the integral is zero (D) \( \vec{E} \) is everywhere parallel to \( d\vec{A} \) along the surface (E) if a charge is placed outside the surface, then it cannot affect \( \vec{E} \) along the surface
