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.
