Pressure and Force: Magnitude of forces

Описание к видео Pressure and Force: Magnitude of forces

7. A glass bottle of soda is sealed with a screw cap. The absolute pressure of the carbon dioxide inside the bottle is 2 x 10^5 Pa. -Assuming that the top and bottom surfaces of the cap each have an area of 4x 10^-4 m2, obtain the magnitude of the force that the screw thread exerts on the cap in order to keep it on the bottle. The air pressure outside the bottle is 1.0x10^5Pa
