Physics - Sound Wave Question with Solution | TestHub

A pipe closed at one end has lengh $0\cdot 8\mathrm{cm}$. At its open end a $0.5\mathrm{m}$ long uniform string is vibrating in its second harmonic and it resonates with the fundamental frequency of the pipe. If the tension in the wire is $50\mathrm{N}$ and the speed of sound is $320\mathrm{m}/\mathrm{s}$, the mass of the string is
