Peppa is practicing his clarinet in the back of her limo and the back window is open so passersby can hear her play. At one moment, Peppa is playing a high G with a frequency of 704 Hz as the limo is moving on the expressway at 65 miles per hour. (temperature outside be a comfortable 73F). What is the frequency heard by the driver of a car with a flat tire on the side of the road as Peppa approaches? What frequency would be heard after Peppa passes? If the sound intensity level heard by the driver on the side of the road is 73 dB, how much sound

power is incident upon his eardrum (9 mm in diameter)?
