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