    Power series: How would you write this off as?

    Whoops. Anyway I rang up the lecturer and the answer was actually, p is infinite for all x but the series converges for all values of x. Sorry again about that.

    Power series: How would you write this off as?

    Sorry about that. Was a typo. anyway the question requires us to find the range of x in which the power series converges. original equation is an=xn/nn By the ratio test for absolute convergence, p= limx->inf |an+1/an| p= limx->inf | [xn+1/ (n+1)(n+1)] x [nn/xn] | p= |x| limx->inf nn/(n+1)(n+1)...

    Power series: How would you write this off as?

    So. There's this question about power series that will eventually take the form of p= |x| lim n->inf | nn / (n+1)(n+1) | But of course, in a futile attempt at a solution I tried doing the derivative for both functions. Didn't get anywhere of course. Knowing that eventually the answer...

    Thermodynamics: Cyclic Processes

    Ohh. So that's how that formula came about. Hmm. I actually used W= -nCvΔT? It worked sufficiently, in a surprising way. But I was wondering how, since V1 and V2 are obviously not the same and Cv is the heat capacity at constant volume? Thanks for the reply though. Really helpful.

    Thermodynamics: Cyclic Processes

    Thermodynamics: Cyclic Processes (solved) Sorry for the false alarm guys. It looked like I did use the wrong equation while finding the internal energy for case 1. referred to this. Thanks. https://www.physicsforums.com/showthread.php?t=412577 Given that 1 mol of ideal monoatomic gas at p= 1...

    Uniform acceleration: air track, data error?

    The length of the track would be just that as mentioned by kuruman, since that is the exact track used in this experiment. I didn't do the measuring for the apparatus personally, aside from handling the stopwatch and glider my partners did the rest, but I'll be matching up data with members...

    Uniform acceleration: air track, data error?

    Actually we used a wooden block to provide inclination? I'm afraid that I should have included that in the description, apologies; We just measured the height gain provided by the wooden block. Which was effectively 0.29 m.edit: Assuming that h is the problem, altering h to be smaller as in...

    Uniform acceleration: air track, data error?

    It's treated as a right angled triangle; So that'll be zero on the other side relative to the higher end, I believe.

    Uniform acceleration: air track, data error?

    h is the maximum height of the inclined plane from the ground while d being the length of the whole plane. In terms of trigonometry it's expressed as sin Ө= 0.29/1.983

    Uniform acceleration: air track, data error?

    Yep. [PLAIN]http://img683.imageshack.us/img683/3620/dataf.jpg [edit] Oh and I used a java app to recalculate the LLSF and again the same answer.

    Uniform acceleration: air track, data error?

    Well, I guess since a= g sin Ө then g sin Ө= 2m= a?

    Uniform acceleration: air track, data error?

    x-x0=(v0t)+1/2(at2); initial distance, x0= 0, initial velocity, v0=0 then x= (1/2)(at2)?

    Uniform acceleration: air track, data error?

    distance, x is the ordinate and t^2 is the abscissa. So that'll be distance versus times squared?

    Uniform acceleration: air track, data error?

    Homework Statement [edit]: In case anyone didn't get a clear picture, in a nutshell the experiment involves us releasing a glider down an air track within a fixed distance x, where the time, t taken is then recorded down. Sorry for not mentioning this before if it's of any use. To determine...

    Arch's Academic Woes: Seeking Encouragement and Opinions

    Hey thanks for the reply guys. Anyway I failed to mention that I am also taking Physics I along with Calculus II this semester? I'll see how well I adapt to it. This thread will be a booster to my confidence. Surely. I'll update my status after my semester closes. @chickenwing71: I did pretty...
