Two persons stand near a railway line separated by a distance 2 km. A detonator is exploded by the first person. The second person 2 km away hears two sounds, one from the sound that has travelling through the rail and the other through the air. What is the interval between them? Given Young's modulus of steel = 2 xx 10^11 N//m^2. Density of steel = 8000 kg/m ""^3. Density of air = 1.29 kg/m ""^3. Atmospheric pressure =1 xx 10^(2) N//m^2. y for air = 1.4
