Parts By Weight
what is the weight of the water displaced by the block of wood?
a block of wood is floating in water. the weight of the part of the block above water is one- third of the total weight of the block. what is the weight of the water displaced by the block of wood. explain in terms of archimedes principle.
please help i dont really understand what they are asking!
According to Archimedes’ Principle, “any body fully or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced”.
The weight of the water displaced is the same as the total weight of the wood block. The fact that 1/3 of the block is above the water level does not matter if you just weigh the total block of wood – then the weight of the total block of wood = the weight of the water displaced by the block of wood. If you want to find density of the block of wood that is a different question – then you need the volume of the block of wood and the information about “one- third of the total weight” .
Hope this helps
