Consider the cube balanced on a cylinder as described in Example 4.7 (page 130). Assuming that b < r, use the Lagrangian approach to find the angular frequency of small oscillations about the top. The simplest procedure is to make the small-angle approximations to before you differentiate to get Lagr

The figure on the right shows three unimodal and symmetric curves: the standard normal (z) distribution, the \(t\)-distribution with 5 degrees of freedom, and the \(t\)-distribution with 1 degree of freedom. Determine which is which, and explain your reasoning.

Dmw Lewis structures for each hypothetical molecule shown below, using the correct number of valence electrons for each atom. Determine which molecule makes sense because each atom has a complete valence shell and each bond has the correct number of electrons. Explain what makes the other molecules n

Diesel Cost and Market Areas Consider Figure 23 , which shows the market areas of sugar-beet processing plants. Suppose that an increase in the price of diesel fuel doubles the cost of hauling sugar beets from farms to processing plants. Modify Figure 23 to show the effects of higher transport costs.

Urban Economics 8
Rural versus Urban Development In the initial equilibrium, a nations workforce of 24 million is divided equally between a city and a rural area. The initial common utility level is $50. The urban utility curve has the conventional hump shape, with a peak at 8 million workers. In the workforce range 8

Introductory Chemistry: A Foundation 9
Explain, in terms of the kinetic molecular theory, how an increase in the temperature of a gas confined to a rigid container causes an increase in the pressure of the gas.
