The trunk of a elephant may extend up to 2.2 m. It acts much like an organ pipe only open at one end when the elephant blows air through it.
1) Calculate the fundamental frequency of the sound the elephant can create with its trunk. (Express your answer to two significant figures.)
(express in Hz)
2) If the elephant blows even harder, the next harmonic may be sounded. What is the frequency of the first overtone? (Express your answer to two significant figures.)
