The German chemist Fritz Haber proposed paying off the reparations imposed against Germany after World War I by extracting gold from seawater.
Given the following data, what was the dollar amount of the gold that could have been extracted from 3.0 m3 of seawater?
- The price of gold at the time was $0.68 per gram of gold.
- Gold occurs in seawater to the extent of 5.15 x 1011 atoms per gram of seawater.
- The density of seawater is 1.03 g/cm3.

- The pressure on Earth's atmosphere as a function of height y above sea level can be determined by assuming g to be constant and that the density of air is proportional to the pressure, i.e., px P. Note that this assumption is not very accurate since temperature and other weather effects can influence pressure. [Hint: Po = 1.013 × 105 N/m², po = 1.29 kg x m-³] (1) Start by finding a relation between the pressure Po and the density of air po at 0° at sea level (y=0) and the pressure P and density p at height y. Using this relation find an expression for p as a function of P, i.e., p = p(P). (2) Find the pressure as a function y. (3) At what altitude above sea level is the atmospheric pressure equal to half the pressure at sea level?A piece of copper whose density is 8.93 g/cm3 has a mass of 180 g in air and 162 g when submerged in a certain liquid. What is the mass density of the liquid?A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.
