Deflate gate was a hot topic before last year's super bowl. according to nfl rule, the football used should be inflated no less than 12 psi. approximately, what is the real pressure of air inside a football when it is inflated to 12 psi? assume the atmospheric pressure is about 15 psi.

27 psi

Explanation:

Given

Minimum pressure inside football is 12 psi

Atmospheric Pressure = 15 psi

We know that

Absolute pressure=gauge Pressure+ atmospheric Pressure

Here Gauge pressure is 12 psi

Absolute pressure =12+15=27 psi

seeing the graph would

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 !
