A boy weighing 1000 N in the air can just float in seawater when almost entirely submerged. What is his volume?
The same mechanism that allows fishes to float in water, hot-air balloons to fly in the air, and for ships to float in the sea despite carrying tonnes of weight has supposedly helped Archimedes (287 BC to 212BC) to find out that the crown (or wreath) of King Hiero II was not made of pure gold, which meant that the king was cheated on by the craftsman of the crown. What is the underlying physics?
A garden hose with an internal diameter of 1.9 cm isconnected to a (stationary) lawn sprinkler that consists merely ofa container with 24 holes, each 0.13 cm in diameter. If the waterin the hose has a speed of 0.91 m/s, at what speed does it leave thesprinkler holes?

- The density of a human body depends on the fraction of fat composing the body, since fat is less dense than muscle. Human fat tissue has a density of about 0.9 kg/liter (900 kg∕m3), so fat floats. Meanwhile the density of fat-free tissue is about 1.1 kg/liter (1100 kg∕m3), so this tissue sinks. Consider two males, both 140 lb. One is a typical American physics professor, who shall go unnamed. With 18% body fat, the density of his body is 1.81 slug∕ft3. The other 140-lb male is Michael Phelps, with a reported 6% body fat, the minimum “essential” fat without being considered medically ill. The mass density of Michael’s body is 1.98 slug∕ft3 and the mass density of water is 1.94 slug∕ft3. What is the volume of the professor's body? Round the final answer to two decimal places.
