mass of One way of restating Archimedes' Principle is that the mass of a block that is floating in a fuid is equal to the the fluid displaced by the block. Imagine that we have a solid block in which all of the sides are 1 cm long-a cube with a volume of 1 cm (Fig.A1.4.2A). We set it in a beaker of pure water and find that, when the block and water come to rest, 70% of the block...

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

A piston with a radius of 2.5 cm is placed into a cylindrical tube a distance of 4.5 cm from the closed end of the tube, holding in a quantity of air. The piston is attached to a spring with a spring constant of 324 N/m. The other end of the spring is attached to a rigid wall. The tube is surrounded in ice water which keeps the gas at a temperature of o°C. Initially, the spring is relaxed, and...
