Homework Statement The problem provides two paths. P1,V1,T1------->P1,V2,T3 (this is the only one i do not understand) for AN IDEAL GAS reversible expansion Pressure---constant Volume---not constant Temperature---not constant Calculate the q(rev)=? work(rev)=? and ΔU=? Homework...

Homework Statement Show how you would find the average distance between gas molecules at a specific volume, pressure and temp? Given; Pressure=P (torr) Temp=T (Kelvin) n=number of mol N=number of molecules Volume=V (cm)^3 Homework Equations pv=nRT N=n*(NA)...

This is extremely helpful. If i have trouble converting the equations into x=rcosθ and y=rsinθ i know now by what you have stated i can still set up and solve (however messy is may be) in terms of x and y and still get the same solution. Ill post a picture later of the two solved integrals...

Thank you for the help, in terms of y I do not know how to do it w/o making it complicated, but... ∫ <(2((2+cosθ)(5+3cosθ)^(2)) , (3((2+cosθ)^(2)*(5+3cosθ))> (dot) <-3sinθ,3cosθ> dθ from 0 to 2pi again thank you for the help.

That is what I was asking, if i can parametrize the entire thing in terms of one variable t, as we are taught in the textbook. so if we have the equation (x-2)^(2) + (y-5)^(2)=9 and we know that x=rcost and y=rsint as a asked can we put (3cost-2)^(2) +(3sint-5)^(2)=9 i do not think you...

okay so if i use the first definition ∫Ndx+Mdy in terms of t i get ∫ ((cost)^(2))*(sint)^(2)) from 0 to 2pi

Thank you for the reply, I greatly appreciate it. Maybe I misunderstood you, the question is stated word for word in the first sentence of the first attachment. As for solving the area integral. I am trying to understand if I can put everything in terms of one variable t. So i do not...

Homework Statement The problem is attached with my work so far. Consider the vector Field F, where C is the perimeter of the circle of radius 3 centered at (2,5) Homework Equations ∫ Mdx+Ndy----->∫∫ (∂N/∂x)-(∂M/∂y) da The Attempt at a Solution Attached is my work thus far. I am having...

okay, I assumed that T=time constant tau or in my case alpha. the answer was correct. thank you for the help

Thank you for the reply, I greatly appreciate it! so here is what i have. A Volt units can be changed into a lot of different units. so μ=(N) / (Amp)^(2) n=turns / (meter) N= Turns I(initial)=Amp Area=(meter)^(2) alpha is (1) / (seconds) so then...

Homework Statement I have attached the two questions. the first has a diagram. 1. Find the MAX Induced EMF (in volts) in the loop by the changing current? 2. What is the magnitude of the EMF induced in the loop by the changing current at t=.8 (seconds) answer in Volts? Homework...

yes, i get the same answer from your (simplified) solution and the same from the two integrals i set up however my problem was i did not set up the limits of integration correctly hence the negative sign. thank you for your help

sorry i forgot the picture.

well i set them up incorrectly that is why i kept coming up with a negative answer. see picture for how i switched them. the worked integral is in the first attached picture however the answer should be positive.

okay, thank you for the reply i greatly appreciate it. using the integrals i set up, after simplifying the two i obtain -((3)*(k)*(Q) / (2)*(R)) which is a similar formula i just found a min ago however there formula did not have a negative sign. so why when my method is correct, do i...
