An ambulance is traveling north at 56.7 m/s, approaching a car that is also traveling north at 36.4 m/s. The ambulance driver hears his siren at a frequency of 726 Hz. Ambulance 56.7 m/s 36.4 m/s Car What is the wavelength at any position in front of the ambulance for the sound from the ambulance’s siren? The velocity of sound in air is 343 m/s. Answer in units of m. 002 (part 2 of 2) 10.0 points At what frequency does the driver of the car hear the ambulance’s siren? Answer in units of Hz.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
