Two test pilots are in identical jets that produce a characteristic tone of 507 Hz. One jet is stationary on the airstrip and the second is approaching the airstrip at a speed of 64.6% the speed of sound. Take the speed of sound in air to be 343 m/s. The pilot of each jet listens to the sound produced by the other jet. Determine the following.
(a) Which pilot hears a smaller Doppler shift?
the stationary pilotthe moving pilot
(b) the frequency heard by the pilot in the moving jet
Hz
(c) the frequency heard by the pilot in the stationary jet
Hz

(a) horizontal distance from where the child releases the rock
to where it lands in the water

Consider the following one-shot Bertrand game. Two identical
firms produce an identical
product at zero cost. The aggregate market demand curve is given by
6 − p , where p
is the price facing the consumers. The two firms simultaneously
choose prices once.
Suppose further that the firm that charges the lower price gets the
entire market and if
both charge the same price they share the market equally. Assume
that prices can only
be quoted in integer units (only...

Two in-phase loudspeakers emit identical 1000 Hz sound waves
along the x-axis.
What distance should one speaker be placed behind the other for
the sound to have an amplitude 1.90 times that of each speaker
alone?

Two identical firms compete in a Bertrand duopoly. The firms
produce identical products at the same constant marginal cost of MC
= $10. There are 2000 identical consumers, each with the same
reservation price of $30 for a single unit of the product (and $0
for any additional units). Under all of the standard assumptions
made for the Bertrand model, the equilibrium prices would be Group
of answer choices $10 for both firms $30 for both firms $50 for
both...

Suppose there are two firms that produce an identical product.
The demand curve for their product is represented by P=60-2Q, where
Q is the total quantity produced by the two firms. The marginal
cost of production is zero and there are no fixed costs.
A. Refer to Scenario: Oligopoly. Suppose both firms choose their
individual quantities q1 (firm 1) and q2 (firm 2) simultaneously
and independently (so Q = q1 + q2). What is the unique Nash
equilibrium price?
B....

Two companies (A and B) are duopolists that produce identical
products. Demand for the products is given by the following demand
function: P = 1,000 - QA - QB where QA and QB are the quantities
sold by the respective firms and P is the selling price. Total cost
functions for the two companies are: TCA = 50,000 + 200QA + .5QA2
TCB = 20,000 + 400QB + QB2

Two companies (A and
B) are duopolists that produce identical products. Demand for the
products is given by the following demand function:
P = 10,000 -
QA - QB
where QA
and QB are the quantities sold by the respective firms
and P is the selling price.
Total cost functions
for the two companies are:
TCA = 500,000 + 200QA +
.5QA2
TCB =
200,000 + 400QB + QB2

Suppose there are two firms operating in a market. The firms
produce identical products, and the total cost for each firm is
given by C = 10qi, i = 1,2, where qi is the
quantity of output produced by firm i. Therefore the marginal cost
for each firm is constant at MC = 10. Also, the market demand is
given by P = 106 –2Q, where Q= q1 + q2 is the
total industry output.
The following formulas will be...
