QUESTION #52 Induced EMF

A rectangular loop of sides 12mathrm~cm$12\mathrm{~cm}$ and 5mathrm~cm$5\mathrm{~cm}$, with its sides parallel to the x-axis and y-axis respectively moves with a velocity of 5mathrm~cm/s$5\mathrm{~cm/s}$ in the positive x-axis direction, in a space containing a variable magnetic field in the positive z-direction. The field has a gradient of 10^-3mathrm~T/cm$10^{-3}\mathrm{~T/cm}$ along the negative x-direction and it is decreasing with time at the rate of 10^-3mathrm~T/s$10^{-3}\mathrm{~T/s}$. If the resistance of the loop is 6mathrm~mOmega$6\mathrm{~m\Omega}$, the power dissipated by the loop as heat is x times 10^-9mathrm~W$x \times 10^{-9}\mathrm{~W}$. The value of x$x$ is:
