Question Answered step-by-step 1. A car horn has a frequency of 448 Hz when the car is stationary…. 1. A car horn has a frequency of 448 Hz when the car is stationary. If the car approaches a stationary recorder at a speed of 19.0 m/s, what frequency does the device record if the temperature is 20°C? What frequency does the device record after the car passes by? 2.  If the recorder in question 14 were moving toward the stationary car at 42 m/s, what frequency would it record? 3. A particular note played on a cello has a frequency of 220 Hz. What is the frequency of the third harmonic of that pitch? 4 . While tuning her guitar, a guitarist compares the pitch one string produces to the pitch produced by a string on another guitar. If the second guitar plays a note with a frequency of 330.0 Hz and the first guitar plays a note with a frequency of 335.0 Hz, what is the beat frequency produced? 5 . The two guitars in Question 19 are playing so that the beat frequency between them is 3 Hz. If one of them is playing a frequency of 348 Hz, what are the possible frequencies the other instrument is playing?              Science Physics SCIENCE 10 Share QuestionEmailCopy link Comments (0)
