5. A 250-volt electrical heater is used to warm 3Li/hr of water from 19°C to 98°C. Assume heat conversion loss of 25% of the total heat supplied, how much current in amperes must be supplied to this heater. Derive with the formula below, show the cancellation, explain the step by step and DRAW a free body diagram/figure. refer with this: PE1 + KE1 + U1 + WF1 + Q1 + W1 = PE2 + KE2 + U2 + WF2 + Q2 + W2 + E losses.

ost Lab Questions: 1. A kilowatt-hour is the unit of energy electric companies use. This is 3,600,000 Joules. You can buy a kilowatt-hour of energy in Colorado right now for around 11.79¢ (the price changes due to the location and time of year). To get a feeling for how much a kilowatt-hour is, consider illuminating ten 100-watt light bulbs (that's 1,000 watts or 1 kilowatt). That's a lot of light. If you kept all of them burning for an hour, that would be a kilowatt-hour. a. How many stairs would you have to run up to create that much energy? b. Would you do that for 11.79¢? 2. Abbie and Bonita decide to race up a hill that is 30 meters high. It takes Abbie 45 seconds since her route is steep while Bonita runs up her path in 30 seconds. They both start from rest at the same height and stop at the top. Abbie has a weight of 700 N while Bonita has a weight of 500 N. Abbie Bonita in going up the hill
