Physics - Wave on String Question with Solution | TestHub

The mass per unit length of a uniform wire is$0.135 \mathrm{g} {\mathrm{cm}}^{-1}$. A transverse wave of the form$y=-0.21\sin \left(x+30t\right)$is produced in it, where$x$is in meter and$t$is in second. Then, the expected value of tension in the wire is$x\times {10}^{-2} \mathrm{N}$. Value of$x$is             (Round-off to the nearest integer)
