Typically either pounds per square inch (PSI) or kilipascals (kPA).
Very useful in the appropriate circumstances.
Air pollution is not useful. It is a problem.
It is not useful because if the liquid run out the car can't stop but if you use air than it is useful as when the air runs out there automatically comes more
air
Basically useful fluke is the flux that flows with in the magnetic circuit of an armature. That is why when there is an air gap the flux enters the armature which makes it useful flux! Hope that answers your question!

it can be used to seal things air tight. it can be used to seal things air tight.
Air resistance is useful in the design of parachutes as it helps slow down the descent of the parachute and the person attached to it. By creating drag as the parachute opens and fills with air, air resistance counteracts the force of gravity and allows for a safe and controlled descent.
