Question

How acid battery hydrometer uses Archimedes principle.

Answer 1

A hydrometer or areometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy. ... Thehydrometer makes use of Archimedes'principle: a solid suspended in a fluid is buoyed by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid.

Answer 2

this is your answer....

The hydrometer makes use of Archimedes' principle: a solid suspended in a fluid is buoyed by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid. The lower the density of the fluid, the deeper a hydrometer of a given weight sinks; the stem is calibrated to give a numerical reading.

hope this helps.....
