Why do you weigh slightly less when on a plane that is flying high in the air

Answer is the explanation

Explanation:

By Newtons Law of gravitation,

F = GMm/r², where r = distance between center of gravity of two bodies exerting gravitational force.

Which says, F ∝ 1/r²

When you are flying in an plane high in air the distance between your center of gravity and that of the Earth is bit more than when you are in Earth surface. But due to r² factor, the little difference makes a sensible change which is why you feel slightly less weight when flying in a plane.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
