A block of wood weight 4kg and has a relative density of `0.6` it is to be loaded with lead so that it will float in eater with `0.9` of its volume immersed. What weight of lead will be needed (a) if the is on top of the wood, (b) if the lead is attached below the wood ? (density of lead `=11,340kgm^(-3)`)

A block of wood weight 4 kg and has a relative density 0.6 . It is to be loabed with lead so that it will folat completely immersed. What weight of lead is needed (a) if the lead is on top of the block (b) if the lead is attached below the block ? Density of lead= 11.34xx10^(3) kg m6(-3)

A block of wood weighs 12 kg and has a relative density 0.6. It is to be in water with 0.9 of its volume immersed. What weight of a metal is needed if the metal is on the top of wood ? [Relative density of metal = 14]

A block of wood floats in water with 2/3 of its volume submerged. Its relative density is

A block of wood floats in fresh water with two-thirds of its volume V submerged and in oil with 0.92V submerged. Find the density of (a) the wood and (b) the oil.

A wood block (mass 3.67 kg, density 600 kg/m) is fitted with lead (density 1.14 xx 10^(4) kg//m^(3) ) so that it floats in water with 0.700 of its volume submerged. Find the lead mass if the lead is fitted to the block's (a) top and (b) bottom

A piece of lead weight 232 g and has a volume of 20 cm^(3) , then the density of lead

A cubical block of wood weighing 200 g has a lead piece fastened underneath. Find the mass of the lead pieces which will just allow the block to float in water. Specific gravity of wood is 0.8 and that of lead is 11.3 . (b) Solve the previous problem if the lead piece is fastened on the top surface of the block and the block is to float with its upper surface just dipping into water.
