Question

A piece of wood of mass 60kg and density 600kg/m3 flows in water of density of 1000kg/m3.calculate (a) volume of water that the wood displaced (b) the fraction of volume of mass and water

Answer 1

short answer:
40% above water
60% below water :)

long answer:

volume of wood = 60 kg (1 m^3/600kg)
= 0.1 m^3

volume of wood under water (see Archimedes)
= 60 kg (1 m^3/1000kg)
= 0.06 m^3

Answer 2

fraction = o.g
