Respuesta :
When a log of wood is put over the freshwater, the log start to float. Option B is correct.
Density:
It can be defined as the amount of substance per unit volume. It is usually denoted by D. It is measured in the [tex]\bold { kg/m^3}[/tex].
The less dense object always floats over the more dense substance.
For example- Here, The density of the log is 0.8 [tex]\bold{ cm^3}[/tex] and the density of the of water is 1.0 [tex]\bold{ cm^3}[/tex] .
Since, the density of the log is lesser than the density of the water.
Therefore, when a log of wood is put over the freshwater, the log start to float.
