Question

A hydrogen filled balloon rises in the air.This is an example for......?

Floatation
Archimedes' Principle
Buoyancy​

Answer 1

Explanation:

The atmospheric pressure is due to the force exerted by the atmosphere on the region below it. But a hydrogen filled balloon rises up in the atmosphere due to density difference only.

Answer 2

Explanation:

HEY MATE ..

The atmospheric pressure is due to the force exerted by the atmosphere on the region below it. But a hydrogen filled balloon rises up in the atmosphere due to density difference only. As the density of hydrogen gas is less than that of air, the hydrogen filled balloon rises up in the air

A balloon filled with hydrogen rises to a certain height as it displaces more wt. ... of balloon but as it rises higher density of air DECREASES there and upthrust becomes less and ultimately upthrust become equal to the weight of balloon and balloon stone rising further .
