The mass per unit length of a uniform wire is 0.135g/cm. 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 $x\times {10}^{-2}$ N. Value of x is________(Round-off to the nearest integer)
