Two test pilots are in identical jets that produce a characteristic tone of 510 Hz. One jet is stationary on the airstrip and the second is approaching the airstrip at a speed of 92.2% the speed of sound. The pilot of each jet listens to the sound produced by the other jet. Assume the speed of sound is 331 m/s. (b) What is the frequency heard by the pilot in the moving jet (4 points)? (c) What is the frequency heard by the pilot in the stationary jet (3 points)?

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...

4. In one of the original Doppler experiments, a tuba was played on a train at a speed of 60 km/h, at a constant frequency of 75 Hz, while a second identical tuba played the same note on the platiorm at the railway station. Assume the observer is standing still on the platiorm on a day when the outside air temperature is 20° C a. What is the effect that is observed regardless of any sound from the tuba at...

Question 2 (a) Using the component method, in adding the two vectors: 14 N in the x direction and 13 N at 45° elevation, (b) : (i) Calculate the momentum of a 8000 kg locomotive travelling at 12 m/s. (ii) This locomotive collides with a stationary carriage of mass 2500 kg and they shunt (stick together). What would be the velocity of the combination, assuming there is negligible friction. (iii) Would kinetic energy be conserved in this collision? Show...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
