2) On a summer day, when the temperature outside is 30.0 °C, I hear a 7.50 x 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.
