Answer 1

Answer:

as you go to higher altitude, the temperature as well as the atmospheric pressure changed. the atmosphere pressure decrease with increasing altitude. because is higher altitude there is low air molecules so their pressure is low and vice versa.Apr 26, 2020

Explanation:

Archimedes' principle states: An object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid. or you may write this also

The Principle states that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.” Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”

Answer 2

Variation of Atmospheric pressure with altitude -

$Air pressure is higher at lower altitudes. Air density is higher at lower altitudes. There is more space between air molecules at higher altitudes. There is less oxygen to breathe at the top of a high mountain than there is at sea level$

What is Archimedes principle?

$Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.$
