Asked by Cindy
On a summer day, when the temperature outside is 30.0 °C, I hear a 7.50×10^2 Hz bell from the clock tower at URI, which I know is 2300. m away from my house.
a) Calculate the speed of sound in air on this day.
b) Calculate the wavelength of the sound.
c) Calculate how long, before I heard the sound, it had been emitted from the clock tower

a. V = 331m/s + 0.6m/s/Co * T
V = 331 + 0.6*30 = 349 m/s.
b. WL = V/F = 349/750 =
c. d = V*T,
2300 = 349T,
T =
V = 331 + 0.6*30 = 349 m/s.
b. WL = V/F = 349/750 =
c. d = V*T,
2300 = 349T,
T =
