![]() If a 440 Hz wave takes 2.27 milliseconds to complete a cycle, then the position of maximum air pressure travels 1. 91, and this means that an increase in the speed of sound by 1 foot per second corresponds to an increase of. Assume that the speed of sound is 1130 ft/s. The slope of T as a linear function of S is. Approx 1 ft/sec change indicates 1 degree of temperature change This also equates to 1235 km/h, 767 mph, 1125 feet per second (ft/s), or 666 knots. In SI units with dry air at 20☌ (68☏), the speed of sound c is 343 meters per second (m/s). (d) Explain in practical terms the meaning of the slope of the function youįound in part (c). The speed of sound has nothing to do with 'sea level' and sound pressure and without the medium air there is no speed of sound. The speed of sound in air is nearly the same for all frequencies. Slope = rise/run, therefore 1.1/1, or just +1.1 The speed of sound in air is approximately 345 m/s (about 1,250 kph, 770 mph, 1,100 ft/s). S has a constant rate of change and is a linear function of T. (Round your answers to two decimal places.)īecause S always increases by 1.1 ft/sec when T increases by. When the temperature T is 32 degrees Fahrenheit, the speed S of sound is 1087.5 feet per second.įor each degree increase in temperature, the speed of sound increases by 1.1 feet per second. The speed of sound in air changes with the temperature. You can put this solution on YOUR website! , and this means that an increase in the speed of sound by 1 foot per second corresponds to an increase of. (d) Explain in practical terms the meaning of the slope of the function you found in part (c). (c) Solve for T in the equation from part (b) to obtain a formula for temperature T as a linear function of speed S. (b) Use a formula to express S as a linear function of T. ![]() , S has a constant rate of change and is a linear function of T. (a) Explain why speed S is a linear function of temperature T.īecause S always increases by 1.1 when T increases by. (Round your answers to two decimal places.) For each degree increase in temperature, the speed of sound increases by 1.1 feet per second. ![]() When the temperature T is 32 degrees Fahrenheit, the speed S of sound is 1087.5 feet per second.
