An electric appliance supplies $\displaystyle 6000$ J/min heat to the system. If the system delivers a power of $\displaystyle 90$ W. How long it would take to increase the internal energy by $\displaystyle 2.5 \times 10^3 \mathrm{~J}$ ?
Official answer
(2)
$\displaystyle 2.5 \times 10^2 \mathrm{~s}$
