Q6. (1) Using the measured speed of sound from longer pipe, estimate the temperature of the lab room, with uncertainty. The speed of sound is given by v 331 +0.6T (m/s), where T is the temperature in degrees Celsius. Does this find the lab room to be significantly warmer or colder than room temperature (say, 20+20C)? Justify using your uncertainties. Also, does this result make sense? Does...

The speed of sound in air (in m/s) depends on the temperature according to the approximate expression below, where TC is the Celsius temperature. In dry air the temperature decreases about 1°C for every 150 m rise in altitude. v = 331.5 + 0.607TC (a) Assuming this change is constant up to an altitude of 9000 m, how long will it take the sound from an airplane at 8800 m to reach the ground on a day when the ground...

The speed of sound through air at room temperature and standard pressure is about 343 m/s. One cue the human hearing system uses to localize sound is the slight difference in the arrival times at the two ears of the sound emanating from a source. Ears are spaced about 20cm apart. Consider a person facing the positive x-direction and a source located 5 m away at an angle of 45° below the positive x-direction. What is the difference in arrival...

The speed of the sound in air is approximately v=331.4 m/s + (0.6 m/c⋅C)T where T is the temperature in degrees Celsius. The speed of the light is 300000 km/s. The speed of the light is so large that in practical terms, involving distances on Earth, the light travels instantly. On a cool night with air temperature of about 10∘C, you see a lightning flash and then hear the thunder rumble five seconds later. How far is the lightning strike?
