Derive the expression for the pressure exerted by the gas on the seal as a function of pressure Pa of the outside air, the force F exerted by Earth on the water, the area A of the water seal, and angle θ . Note that surface tension keeps the water-gas interfaces essentially perpendicular to the tube. Express your answer in terms of the variables Pa , F, A, and θ.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
