Earths oceans have an average depth of 3800 m, a total area of \(3.63\times10^8\ \text{km}^2\), and an average concentration of dissolved gold of \(5.8\times10^{-9}\ \text{g/L}\). (a) How many grams of gold are in the oceans? (b) How many m3 of gold are in the oceans? (c) Assuming the price of gold i

a) By examining the effective potential energy (8.32) find the radius at which a planet (or comet) with angular momentum can orbit the sun in a circular orbit with fixed radius. [Look at dUeff I dr 1 (b) Show that this circular orbit is stable, in the sense that a small radial nudge will cause only s

Paris versus Detroit Suppose the benefi t and cost curves of the high-income households shown in Figure 7A2 are relevant for Detroit. In contrast, high-income households in Paris take 50 percent more trips to the city center (for work and cultural opportunities). While Detroiters commute in air-condi
