A transverse wave described by equation $\mathrm{y} = 0.02 \sin (\mathrm{x}+30\mathrm{t})$ (where x and t are in metres and seconds, respectively) is travelling along a wire of area of cross-section 1 ${\mathrm{mm}}^2$ and density 8000 $\mathrm{kg}/{\mathrm{m}}^3$. What is the tension in the string?
