pressure is force per unit of area?

Question

TRUE OR FALSE

Answer 1

True.

Answer 2

Since P = F/A and F is one Newton and area is m^2. But F = mass x g (gravity pull) = 1034 g x 9.86 m/sec^2 But 1 newton = 1 kg-m/sec^2 and 100 cm = 1 m Doing the conversions, you get 1034 x 9.86 x 10^4/(10^3) = 101,952 Pascals which is close to accepted value 101,325 Pa = 1 atm However, sometimes the acceleration due to gravity is given as 9.81 approximately, so this will give you 101,435 Pa And if you just use 9.8 as given in most texts, then you get 101,332 Pa. So, you are all right.

Answer 3

true ,,

P = F / A

where P : pressure ( bar , N/m^2 , Pascal )

F : Force in Newton N

A : Area in Square metre . m^2

Note :
The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). The word bar is of Greek origin, báros meaning weight. Its official symbol is "bar"; the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.

Answer 4

yes pressure is the force per unit area
P = F/A
also pressure= mass mutiplied into acceleration
= m. a

Answer 5

true
