In the circuit, a 20-ohm resistor sits inside 115 gg of pure water that is surrounded by insulating Styrofoam. If the water is initially at temperature 11.6 ∘C, how long will it take for its temperature to rise to 58.8 ∘C? Use 4190 J/kg⋅∘C as the specific heat of water, and express your answer in seconds using three significant figures.
