I posted this question earlier but I don't quite understand the development for part b) and c). I need some details because it's really not obvious for me. Part a) is good.

The question is :

We start the operation of a reversible Carnot Engine between two reservoir of temperature T1 and T2 where T2 > T1. The colder reservoir is so cold that his temperature doesn't change during the process of the engine. The hotter reservoir is composed of a limited quantity of monoatomic ideal gas with a specific heat CV that is known. (CV is constant between temperature T1 and T2 ). After a period of time , the temperature of the hot reservoir is reduced to T1.

a) What is the change in entropy of the hot reservoir during that period ?

b) What is the total work done by the engine after this period ?

c) What is the change of entropy of the system (the Carnot engine) during this that period ?

I have posted this earlier, but it seems that the code part was cutoff, therefore, this is re post with full code. In the program the "case: 'C'" doesn't seem to function correctly, We were told to write a book tracking program, and it takes inputs and once all the book info such as ISBN, date, author, course number, etc are put in then input, then we can print them out, by using the print functions that are defined in...

I saw an answer for this on another question posted, but I don't think the answer was exactly what I was looking for. Can anyone help guide me in the right direction in regards to this question and its subquestions? Thanks. The proton and electron are particles found to have equal and opposite charges to the precision that the measurements have been made so far. Why is it important that the proton and electron have exactly the same magnitude for...

5 more questions from the first post that I made. Posting questions I don't quite understand or need some help with. Suppose we want a 93% confidence interval for the average amount spent on books by freshmen in their first year at a major university. The interval is to have a margin of error of $2, and the amount spent has a Normal distribution with a standard deviation σ = $30. The number of observations required is CLOSEST to: 28....

HI, I hope you are doing well. I really don't understand this question and don't know how to solve it at all because I am completely new to this c++ programming. can you please explain each line of code with long and clear comments? please think of me as someone who doesn't know to code at all. and I want this code to be written in c++ thank you very much and I will make sure to leave thumbs up....

I posted a question yesteraday and got an answer. There is a second part to the question Problem 6-4AA Periodic: Alternative cost flows P3 Refer to the information in Problem 6-3A and assume the periodic inventory system is used. Required Compute cost of goods available for sale and the number of units available for sale. Compute the number of units in ending inventory. Compute the cost assigned to ending inventory using (a) FIFO, (b) LIFO, (c) weighted average, and (d)...

I am not quite sure what this question is asking, nor do I understand how to apply the lower-of-cost-or-NRV. The controller of Alt Company is applying the lower-of-cost-or-net realizable value basis of valuing its ending inventory. The following information is available: Cost Net Realizable Value Lawnmowers: Self-propelled $14,800 $17,000 Push type 19,000 18,000 Total 33,800 35,000 Snowblowers: Manual 29,800 31,000 Self-start 19,000 21,000 Total 48,800 52,000 Total inventory $82,600 $87,000 Compute the value of the ending inventory by applying the...

The bold part is what I don't understand. A country with a negative current account is because NX < 0 loanable fund mrkt; open econ. If country M>X, NX=<0 so S-l=<0 which means there is more investment into the country than domestic savings because NX is matched with a counter-flow that is NFI (Net Foreign Investment). There is going to be NFI in a country that imports more than it exports Ex: US. They import more than they export. Meaning...

hi i don't understand for question b #3 & 4 Having thought about Mr. James’s suggestion, you consider several options as an estimate of lost profits. These include 1) the full year, 2) the last six months only, 3) a weighted average that gives twice the weight to the last six months as to the first six months, or 4) some other weighted average. Which method do you think gives the most accurate estimate of lost profits?
