Given: F = 300 N; `"A" = 30 " cm"^2 = 30/(100xx100)"m" ^2 = 30xx10^-4 "m"^2`
To Find: Pressure
`therefore "P" = "F"/"A"`
`= 300/(30/(100xx100)`
` = (300xx100xx100)/30`
= 100000
= 105 Pa
Calculate the pressure in pascal exerted by a force of 300 N acting normally on an area of 30 cm2.

Explain why The blood pressure in humans is greater at the feet than at the brain
The pressure and thrust are related as
Define the term ‘pressure’ and state its unit.
How is the thrust related to pressure?
Pressure is directly proportional to the area of contact.
What is an Artisan aquifer?
The shape and size of the solids do not easily change.
Assertion (A): A sleeping mattress is so designed that when you lie on it, a large area of your body comes in its contact.
Reason (R): This reduces the pressure on the body and sleeping becomes comfortable.
Define thrust.
