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

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 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 Assume that the firms form a cartel to maximize total industry...

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...
