Archimedes Principle - Upward Tension Additional Force As shown in the above figure, a solid object has a density of 1200 kg/m3 and a volume of 7.80x10^-5 m3. It is lowered on a string into water and completely submerged without touching the container. The density of water is 1000 kg/m3. Keep 3 decimal places in all answers. (Don't use scientific notations.) Without the string, would the solid object sink in water or float in water?...

A cube of iron and a cube of wood, each having a volume of
V = 1.45 10-4 m3, are each placed in
a large beaker of water. The density of the wood is
ρwood = 3.73 102 kg/m3 and the density
of the iron is ρiron = 7.86 103 kg/m3. Calculate the
buoyant force on each. (The cube of wood is allowed to float at the
surface.)
