Hey all, I'm not sure this is a homework problem, more a problem I'm having with equations and this effect. Experimentally we measured dT and dp, I plotted them, then determined the Joule Thompson coefficients for 3 gases (He, CO2, N2). These values came out to be μJT(CO2) = .815 bar/K...

Ah I see now, I didn't even realize the Cl would be a nucleophile (it makes sense that it is, I just didn't look at it that way for some reason). Thanks for clearing that up.

Thank you :) I bookmarked that page for future use, I'd never been there before but it seems like it has a lot of good info.

Hi all, I am studying for an exam tomorrow and can't seem to find this mechanism anywhere. I know that a Br and a Cl are added in Markovnikov fashion but I don't know which would be added first and which would go on the more substituted carbon. Any help is appreciated. Thanks

Thanks, I'll look that up. And you I do have a calculator so maybe I'll try to figure out the matrices, though I haven't dealt with them for a while... Also, my teacher decided to extend it a couple days so apparently I wasn't the only one procrastinating :biggrin: The original question...

I've been learning about that since high school :redface: lol. Thank you for the help, did you get the other two values by plugging the value you got for the middle current into the previous equations? Also, you said that substitution may take a while...do you have another technique for...

I was trying to use Kirchhoffs current rule for my first equation, where at the junction point on the right in the middle I2-I1-I3=0. But I see where I could use the third loop. Is -EB+75I1-22I3+5=0 correct? I am kind of confused where you wrote -EB+56I1+75I2, doesn't the 75 ohm...

Any tips? It's due in an hour and I still can't figure out where I've gone wrong :( I've done it a few times from the beginning and still have gotten the same answer...

For a, The sum of the forces in the x direction = ma Pulling force + Frictional force = m(0) (remember + or - signs depending on direction, friction acts against movement) I think that should help. For b, use the same value of the frictional force from part a, then Pulling force...

Bump...I am working on a similar problem and having trouble with part b. I have found the torque and I thought to find work I could use w=td where t is torque and d is rotational distance. What am I missing?

Ah I see. I'm glad I was able to make it through (eventually) doing it the basic way, but I do see how that equation would be helpful for those more complex problems. Thanks again to both of you for the help.

Ahh geez... I had been doing that the whole time and I never realized it, thank you for pointing that out. That makes things work out. Here are the equations I ended up with, I actually set positive x up the incline on the pumpkin side and down the incline on the watermelon side and I think...

Ok I think I can figure this out...but solving both equations for T and then substituting it into the other equation gave me a=.106m/s^2 which was incorrect. Do I need to solve one in terms of a and substitute that way?

Ok I am having problems with this. If down the pumpkin slope is positive, then -T=-m_pumpkin*gsin53+m_pumpkin*g*a and for the watermelon T=m_watermelon*gsin30+m_watermelon*g*a I don't think I understand how the direction on one slope relates to the direction on the other. Do I...
