Question

30.4 centimetre cube find the other with the piece of wood float or sink in the water​

Answer 1

we know, relative density is the ratio of density of substance to density of water at 4°C . we know, any object floats in the water only when density of object will be less than density of water. so, wood floats in the water.

Answer 2

Explanation:

In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level. An object with a density of 0.5 g/cm3 will sit half in and half out of the water. Three-quarters of an object with a density of 0.75 g/cm3 will be submerged.
