The pressure wave, P=0.01 \sin [1000 t-3 x] N m^{-2} , corresponds to the sound produced by a vibrating blade on a day when atmospheric temperature is 0^\circC. On some other day when temperature is T, the speed of sound produced by the same blade and at the same frequency is found to be 336ms^{-1} . Approximate value of T is: [9 Apr 2019 Shift 1]

The pressure wave, P=0.01‌sin[1000t−3x]‌N‌m−2 , corresponds to the sound produced by a vibrating blade on a day when atmospheric temperature is 0°C. On some other day when temperature is T, the speed of sound produced by the same blade and at the same frequency is found to be 336ms−1 . Approximate value of T is:
