Answer:

C) >A)>B)

Explanation:

We know that force per unit area is known as pressure.But we have to understand that this force should be perpendicular to the area.

 P = F/A

P=Pressure

F= Force

A=Area

A)

Given that

ΔP=2.9 N/m²

A=1500 m²

F= ΔP x A

F= 2.9 x 1500

F=4350 N

B)

Given that

ΔP=4.7 N/m²

A=900 m²

F= ΔP x A

F= 4.7 x 900

F= 4230 N

C)

Given that

ΔP=8.8 N/m²

A=500 m²

F= ΔP x A

F= 8.8 x 500

F=4400 N

4400 N > 4350 N > 4230

C) >A)>B)
