You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30°C to 36°C. What's the velocity of the sound wave at this new temperature? A. 335.6 m/s B. 352.6 m/s C. 344.0 m/s D. 350.0 m/s
The equation relating the velocity of sound in air to the air temperature is: v = 331 + 0.6T, where T is the temperature in degrees Celsius. For this case, when T = 36 C: v = 331 + 0.6(36) = 331 + 21.6 = 352.6 m/s, which is choice B
