I am so stupid, I didn't even pay attention to the details that's all. But I have been working on physics problems from 5pm to 2pm straight up because I have an exam tomorrow. So thank you very much guys for helping me to understand how stupid I was asking that stupid question. Cheers

I wanted to understand this solution: F = P x A = 0.45 x 1.013x10e5 x 1200 F= 5.47 x 10e7 Why we are multiplying the difference pressure between the air and the cabin by the pressure at sea level? Thanks for the warm welcoming

Homework Statement 5. The air pressure at sea level on a cold day is P0 = 1.013 x 105 Pa. At 10.0 km above sea level the air pressure is 0.30 P0 ; however a commercial jet plane keeps the pressure in the passenger and crew section at 0.75 P0 . If the surface area of the cabin structure is...
