Which of the following statements about air is true? . a.. air is not a source of resistance.. b.. air has mass, but not inertia.. c.. air is not affected by human movement.. d.. none of these statements are true.

None of the statements about air is true. Correct D Statement A is false, because air is a source of resistance (air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air). Statement B is also false. Air has the tendency to keep moving in a straight line at a constant speed, when no forces are upon them and that is inertia. Statement C is also false, because  air is affected by human movement.

ANSWER: D.. None of these statements are true.

EXPLANATION: Air is neither a source of resistance nor it has its own mass. Air is also not affected by human movements. It is not a resisting medium when electricity tries to pass through it. Also heat can pass through it like solids.
