- 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 PaytonWhat is the stoppage potential, in volts? That is, the (negative) voltage that you have to apply such that the current just becomes zero?I would love a detailed explanation for this problem. In a phasor diagram, how do we, approximately, know where Vrms will be located? It is known that Vl leads current while Vc lags current by 90 degrees. But what about Vrms in relation to current or in general?
