Question

define the following terms (a) pressure



​

Answer 1

Answer:

Pressure means how much something is pushing on something else. It is expressed as force per unit area: P=F/A. In technology, pressure is often specified in multiples of atmospheric pressure. It can also be defined as the thrust (compressive force acting perpendicularly to the surface of a body) acting per unit area.
