A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. If the speed of sound in air is 320m//s , find the tension in the string.

Two trains A and B moving with speeds 20m//s and 30m//s respectively in the same direction on the same straight track, with B ahead of A . The engines are at the front ends. The engine of train A blows a long whistle. Assume that the sound of the whistle is composed of components varying in frequency from f_(1) = 800 Hz to f_(2) = 1120 Hz , as shown in the figure. the spread in the frequency (highest frequency - lowest frequency) is thus 320 Hz . the speed of sound in still air is 340 m//s . The spread of frequency as observed by the passenger in train B is
