Which object will sink in freshwater, which has a density of 1.0 g/cm3? object 1, which has a density of .08 g/cm3 object 2, which has a density of 1.9 g/cm3 object 3, which has a density of .06 g/cm3 object 4, which has a density of .03 g/cm3

Answer is Object 2 (which has a density of 1.9 g/cm³).

Explanation;

When object is floating, the weight of that object is less than the up thrust on it. When an object fully submerged and floating, then the weight of that object is equal to the up thrust on it.This is known as the Archemide's principle.Both up thrust and weight depends on the density. Hence, if the density of the solution is high, then the up thrust also high. If the density high, the the weight of the object also high.Hence, to sink the object in water, that object should be denser than water. Hence, answer is object 3 which has a higher density than water.

Which object will sink in freshwater?

Object 2, which has a density of 1.9 g/cm³

It conforms what ever surface its in.
