WebAug 24, 2024 · Solution 9N. Time taken by the observer to hear the sound of the first tank A= 3.5s. Time taken by the observer to hear the sound of the second tank B = 2s. Time taken by the tank B to hear the sound of tank A= (3.5 – 2)s = 1.5s. Distance between the two tanks = 510m. Speed = 510/1.5=340m/s. WebA transverse sinusoidal wave of amplitude a, wavelength λ and frequency f is travelling on a stretched string. The maximum speed of any point on the string is v / 10, where v is the speed of propagation of the wave. If a =10 3 m and v =10 m / s, then λ is given by A. λ=10 3 mB. λ=π× 10 2 mC. λ=2 π× 10 2 mD. λ=10 2 m
