A crude approximation of voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. What is the fundamental frequency if the tube is 0.240 m long, by taking air temperature to be 37.0°C? Number 367 Hz What would this frequency become if the person's breathing passage was filled with carbon dioxide instead of air? Assume the same temperature dependence for carbon dioxide as for air. Number 1070 Hz

A crude approximation of voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. (See Figure $17.32 . )($ a) What is the fundamental frequency if the tube is $0.240-m$ long, by taking air temperature to be $37.0^{\circ} C?$ (b) What would this frequency become if the person replaced the air with helium? Assume the same temperature dependence for helium as for air.

(a) What is the fundamental frequency if the tube is $0.240 \mathrm{m}$ long, by taking air temperature to be $37.0^{\circ} \mathrm{C}$ ? (b) What would this frequency become if the person replaced the air with helium? Assume the same temperature dependence for helium as for air.
A crude approximation of voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. What is the fundamental frequency f1 if the tube is 0.240 m long, by taking the air temperature to be 37.0 °C? f1 = Hz What would this frequency become if the person's breathing passage were filled with hydrogen instead of air? Assume the same temperature dependence for hydrogen as for air: f1,hydrogen Hz
