The mass per unit length of a uniform wire is 0.135 g/cm. A transverse wave of the form $\mathrm{y}=-0.21\sin (\mathrm{x}+30\hspace{0.17em}\mathrm{t})$  is produced in it, where x is in metre and t is in second. Then, the expected value of tension in the wire is ${\text{x×10}}^{\text{-2}}\text{N}$  . Value of $\mathrm{x}$ is ________
