In the circuit in the figure,a 20-ohm resistor sits inside 115g
of pure water that is surrounded by insulating Styrofoam. If the
water is initially at temperature 12.0 ∘C, how long will it take
for its temperature to rise to 58.3 ∘C? Use 4190J/kg⋅C∘ as the heat
capacity of water, and express your answer in seconds using three
significant figures.
