Physics - Wave on String Question with Solution | TestHub

The linear density of a vibrating string is$1.3\times 10^{-4}\mathrm{ }\mathrm{k}\mathrm{g} {\mathrm{m}}^{-1}$. A transverse wave is propagating on the string and its described by the equation$\mathrm{y}=0.021\sin \left(\mathrm{x}+30\mathrm{t}\right)$, where$\mathrm{x}$and$\mathrm{y}$are measured in$\mathrm{m}$and$\mathrm{t}$in$\mathrm{s}$. The tension in the string is
