I need the answers to the boxes only Tutorial ExerciseA well-insulated electric water heater warms 116 kg of water from 20.0° C to 42.0° C in 24.0 min. Find theresistance of its heating element, which is connected across a 240-V potential difference.Part 1 of 5 - ConceptualizeWe expect the water heater to be high-powered compared to other household appliances. For the power to beon the order of kilowatts, the current would be several amperes and the resistance only a few ohms.Part 2 of 5 - CategorizeWe will find the energy required to heat the water. Then we will find the power of the heating element andcalculate its resistance from the power and the potential difference.Part 3 of 5 - AnalyzeWe know the mass of water m and the temperature change AT. The specific heat of water isC = 4 186 J/kg • °C. For the energy input by heat, we haveQ = mcAT116kg) (4 186 J/kg · °C)20°C)Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.2.039Your response differs from the correct answer by more than 10%.
