You are on a plane traveling on a 23hr flight to Fort Wayne fromWest-Nowhere. The attendant forgets to close the dividing curtains,and five minutes after takeoff a two - month old baby in 1st classstarts to scream at 3500.0 Hz with a sound level of 122 dB at adistance of 10.0 cm from the baby's mouth. Your seat in "lastclass" is 7.0 m (approx. 21 feet away). What is the sound intensityat your ear (in W/m^2)? Assume the baby is an isotropic source(same at all angles) when radiating sound.
