The mass of a floating object equal the mass of the fluid displaced by the object according to Archimedes's Principle. Use this principle to solve the following:
a. What is the density of the wood if a wooden cylinder 30.0 cm high floats vertically in a tub of water (which is having the density=1.00g/cm3).The top of the cylinder is 14.1cm above the surface of the liquid.
b. What is the liquid density when same cylinder floats vertically in a liquid of unknown density. The top of the cylinder is 20.7 cm above the surface of the liquid.
