A .524kg object is tied down to the bottom of a container which container an unknown fluid. the tension in the rope is 38.5N. the object displaces .00735m3 of unknown fluid. Find the density of the unknown fluid.
M*g = 38.5, M = 38.5/g = 38.5/9.8 = 3.93 kg. = Wt. of fluid displaced.
Density = M/V = 3.93kg/0.00735m^3 = 534.5 kg/m^3.
