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...
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...

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

Attached is my work thus far. I am having...
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
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...
