Car 1 drives directly east at 40 m/s toward Car 2. Car 2 has a velocity of 5 m/s directly west. They each honk their horns with a constant harmonic tone of 400 Hz as they drive toward each other. Which car hears the other car's horn at the higher frequency? A)They both hear the same tone.  b)Car 2 hears the higher tone C)Car 1 hears the higher tone

A section of drainage culvert 2.25 m in length makes a howling noise when the wind blows across its open ends.  Take v=334m/s  as the speed of sound in air.     Determine the frequencies of the first harmonics of the culvert if it is cylindrical in shape and open at both ends._____Hz Determine the frequencies of the first overtone of the culvert if it is cylindrical in shape and open at both ends._____Hz Determine the frequencies of the secon overtone of the culvert if it is cylindrical in shape and open at both ends._____Hz What are the lowest natural frequencies of the culvert if it is blocked at one end?_____Hz What are the second lowest natural frequencies of the culvert if it is blocked at one end?_____Hz What are the third lowest natural frequencies of the culvert if it is blocked at one end?_____Hz What is the ambient temperature?_____Celsius

A car horn has a frequency of 720 Hz. In which of the following situations would you hear an average frequency of 760 Hz? Your answer: the car is moving toward you the car is moving away from you you are higher than the car (like on the third floor) you and the car are both stationary

What happens to a sound source that is passing by at constant speed? A The sound and pitch vary depending on the distance of surrounding objects. B The sound keeps a constant, higher pitch as the source approaches and a constant, lower pitch as the source recedes. The sound keeps a constant, lower pitch as the source approaches and a constant, higher pitch as the source recedes. The sound maintains the same pitch except at the moment when it passes an object. ©2021 Illuminate Education TM Inc. hp esc 23 ト
