Question

What is the force needed to produce a pressure of 1pascal over a square area of side 2m

Answer 1

$\large{explanation}$

pressure over a square area is 1 pascal

area of the square with side 2m

=2x2=4msquare

then force exerted on the square area is

$pressure = \frac{force}{area}$

$1pa = \frac{force}{4m {}^{2} }$

$force = 4newton$

...

Answer 2

Answer:

the answer is ;

Explanation:

➡️ P = F/A

F = P x A

F = 1 x (2)².... as area of square is (side)²

F = 4 N ✔️✔️
