What would be a mathematical model for the diffusion constant,
D?
If the average total displacement in either the x or y direction
is 0 for all times, why is the displacement NOT zero? How does the
displacement change with time?
a) Why would there be a mathematical relation between the
dissociation constant of a weak acid and the pH of a solution?
Write the HH equation as a generalized mathematical expression.
b) What is the relation between the concentrations of a weak
acid and its conjugated base when the pH of the solution is
identical with the acid’s pKa? Explain
A monopolist is able to produce at a constant average total and
marginal costs (ATC = MC = 5). The firm faces a market demand curve
with the following equation P = 53 - Q.
*Determine the equation that gives the firm's marginal revenue
curve.
*Determine the firm's profit-maximizing output level and the
price that they would charge for their product. Determine the
monopolist's profits.
*Determine the output level that would be produced within this
firm under perfect competition. (P...
1. Average fixed costs
are always greater than average total costs
are constant as Q increases
are minimized when MR=MC
decrease and then increase as Q increases because of
specialization
always decrease as Q increases because fixed costs are
constant
2. Deadweight loss is guaranteed to occur when
the maximum level of total welfare (total surplus) is not
achieved
producer surplus is reduced
producer surplus is greater than consumer surplus
tax revenue is positive
consumer surplus is reduced

Suppose that a monopolist has a constant average total cost
of production and marginal cost of production equal to $6, and has
a demand for its product represented as

Calculate the total and marginal revenue for each quantity
produced and sold
Find the profit-maximizing (optimal) quantity produced and
sold and the price/unit.
Calculate the profit or loss at the optimal quantity of
production and...
An optical interferometer can detect a displacement of
0.1?, or ?50nm.
At what speed would a 3.0m stick "shrink" by 50 nm?
Hint: Use the binomial approximation.
