A conducting circular loop of area $\displaystyle 1.0 \mathrm{~m}^2$ is placed perpendicular to a magnetic field which varies as $\displaystyle B=\sin (100 t)$ Tesla. If the resistance of the loop is $\displaystyle 100 \Omega$, then the average thermal energy dissipated in the loop in one period is $\displaystyle \_\_\_\_$J.
