    Diagrams Work
AI Thread Summary
The discussion focuses on calculating the work done by a gas during a specified thermodynamic process using PV diagrams. The initial attempt at the solution involved using the equation W = PVln(V2/V1), but the user encountered an error indicating a multiplicative factor issue. A suggestion was made to consider using the ideal gas equation W = nRT ln(V2/V1) instead. Ultimately, the user resolved the issue independently. The thread highlights the importance of correctly applying thermodynamic equations in problem-solving.

Homework Statement



Calculate the work done by the gas during process 1-> 3-> 6.
Express your answer in terms of Po and Vo.


Homework Equations



W=integral(pv) from V1-V2
W=PVln(V2/V1)

The Attempt at a Solution



3Po*V*ln(3Vo/Vo)

I'm not sure what I'm doing wrong, it keeps telling me I'm off by a multiplicative factor.. Should I be using W=nRT ln(V2/V1) ?

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
