A car is driving toward you with a speed of 86 km/hr. The roof racks on the car emit a whistling sound, which you hear as a 514 Hz tone. If you are stationary, what will the frequency of this tone be to the driver of the car? Use the speed of sound in air as 340 m/s. Tuning a Violin A violin string in too tight, giving a higher pitch than desired. When played alongside a tuning fork of frequency 494, beats are heard at a rate of 4.1 per second. What is the frequency of the out of tune violin string? Put your answer in Hertz and do not give units. Answer must be correct to one decimal place.
