STEP 2. In the previous activity you also considered a situation in which aperson turned a generator, which in turn lit a bulb. The G/R diagram for thissituation is shown below, with a dashed box showing a system consisting ofthe person, generator, bulb, light receivers and the surroundings. Theappropriate values for energy transfers and changes are also shown.Increasein TE+40 JIncreasein TE+16 JIncreaseHeat Interactionsin TESurroundingsEnergy40 J+132.5 JHeat InteractionsPersonSurroundingsEnergy16 JEnergy160 JHeat InteractionsGenerator(90%)Energy132.5 JSurroundingsContact Push/PullEnergyInteraction144 JBulbDecreasein CPE(8%)Energy11.5 JElectric Circuit-200 JInteractionLightReceiversLight InteractionIncreasein energy+11.5 JFor the example in STEP 1 we wrote this more general statement ofconservation of energy.

15.8 The US auto industry produces approximately 6 million vehicles a year, each containing roughly 1.5 metric tons of fabricated metal. Consider a future wind-turbine industry having half of the auto industry ’ s mass throughput of wind-turbine units. Each unit has a specific weight of 75 kg/kW e rated (nacelle components plus tubular tower only). a. At a wind-turbine capacity factor of 0.3, how long would it take to replicate the 2008 US-installed average electric power rating of 1,035 GW e ? b. Discuss the relevant factors that would determine whether a wind-machine industry of this size could be successfully operated sustainably over periods on the order of several centuries.

The average American daily diet consists of 2,400 kilocalories. A kilocalorie contains 4814 J. Assume that this daily intake of kilocalories is completely metabolized at a uniform rate over a 24 hour period. What is the average power generation of the average American over the 24 hour period? Report your answer in units watts (W). I recieved 4814W per 24 hours but am unsure if I am correct.
My physics class has turned to online due to the COVID-19 and I am having trouble with some of the word problems my teacher gave me to work on. She presented me with: I am contemplating a career change. If I had 500g of stolen gold jewelry, how much energy would I have to add to it to melt it (so that it was not longer recognizable)? Pretend that it is pure gold. Would you be able to show me how to accomplish this problem so I can see the steps? Thank you for your time. John Payton
