Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answerarrow_forwardWhich of the following equations is a mathematical statement of the Joule's Law of Resistive Heating? O The time rate of conversion of electrical energy to heat energy is directly proportional to the voltage across through the resistor. O The time rate of conversion of electrical energy to heat energy is directly proportional to the square of the voltage across through the resistor. O The time rate of conversion of electrical energy to heat energy is directly proportional to the current passing through the resistor.

- An electric hot plate raises its own internal energy and the internal energy of a cup of water by 15000 J, and there is at the same time 2900 J transferred to the cooler air (that is, Q = -2900 J). How much energy was transferred to the hot plate in the form of electricity? electric energy input = iarrow_forwardThe “Energy Guide” label on a washing machine indicates that the washer will use $85 worth of hot water per year if the water is heated by an electric water heater at an electricity rate of $0.113/kWh. If the water is heated from 12 to 55°C, determine how many liters of hot water an average family uses per week. Disregard the electricity consumed by the washer, and take the efficiency of the electric water heater to be 91 percent.arrow_forwardWater flows through a shower head steadily at a rate of 10 L/min. An electric resistance heater placed in the water pipe heats the water from 16 to 43°C. Taking the density of water to be 1 kg/L, determine the electric power input to the heater, in kW. In an effort to conserve energy, it is proposed to pass the drained warm water at a temperature of 39°C through a heat exchanger to preheat the incoming cold water. If the heat exchanger has an effectiveness of 0.50 (i.e., it recovers only half of the energy that can possibly be transferred from the drained water to incoming cold water), determine the electric power input required in this case. If the price of the electric energy is 11.5 ¢/kWh, determine how much money is saved during a 10-min shower as a result of installing this heat exchanger.arrow_forward
- If 370 J of work is performed with 45% efficiency, what is the amount of energy that goes into heating, parasitic losses, etc.? Give your answer in units of joules, to three significant figures.arrow_forwardI often make tea in my microwave oven. I know that it takes two minutes to bring the temperature of a cup of water from room temperature to just about boiling: ready for the teabag. I looked up the characteristics of a microwave oven. Typically their power rating is about 1000 W, but I know that this is the power consumed from the power company, not the power delivered to the water. I looked up the efficiency of microwave ovens, and found that it is about 64%, meaning that a typical oven delivers 640 W to the water. I also looked up the frequency of the microwaves that an oven uses, and found thatf= 2,450 MHz. (a) How much energy is delivered to the water in the making of a cup of tea?
