Question

calculate the force on an area of 144cm square to exert preasure of 20 pascal

Answer 1

Answer:

P = F/A

F= P*A

= 12*1 * 144*1/^-4 (1pascal = 1 N/m^2)

= 1728 N /m ^2

Answer 2

Answer:

0.288 N

Step-by-step explanation:

we know that,

pressure = force/area

so,

force, F = P×A

F = 20N/m² × (144/10²×10²)m²

= 0.288 N
