A Show The Fractional Change In The Speed Of

(a) Show that the fractional change in the speed of sound (du/u) due to a very small temperature change d T is given by du/u = 1/2dT/T. (Hint: Start with Eq. 16.10.)
(b) The speed of sound in air at 2Q°C is found to be 344 m/s. Use the result in part (a) to find the change in the speed of sound for a 1.0°C change in air temperature.
