superspeed49 Posted May 9, 2015 Author Report Share Posted May 9, 2015 TZ2 here. I thought paper 2 was a gift from satan, I don't know how you guys found it easy. I chose questions 7 and 8.Paper 1 was so-so. Did anyone get a ton of A's in paper 1? Or is it just me I'm really hoping paper 3 won't be too hard. How did you find question 7? I found Q7 alright, might have messed up a bit when calculating the mass. I used the equation Ek=.5mω^2x^2 to get the mass and got 3.something :/ Hbu? Why 5? I used the same equation, but I got something like 0.27 kg. TZ2 here. I thought paper 2 was a gift from satan, I don't know how you guys found it easy. I chose questions 7 and 8.Paper 1 was so-so.

Also, how did you draw the graph for the KE of particle B? I also got something like this with mass and my graph started at -0.1 and ended at 0.1 and it reached a quarter height Same Reply Link to post Share on other sites More sharing options...

Also, how did you draw the graph for the KE of particle B? 1/2 the amplitude and 1/2 the displcement . YoU? Got half the displacement but a quarter of the max KE... And you couldn't draw the amplitude? 1 Reply Link to post Share on other sites More sharing options...
ordinaryguy Posted May 9, 2015 Report Share Posted May 9, 2015 i deduced that according to the formula, if max displacement is halved, then the max energy is 1/4 2 Reply Link to post Share on other sites More sharing options...

I also got something like this with mass and my graph started at -0.1 and ended at 0.1 and it reached a quarter height I got exactly the same, the energy reached 1/4 of the graph for A, which was around 0.04J, and its displacement was from -0.1 to 0,1, phew!! 1 Reply Link to post Share on other sites More sharing options...
whydidiprocrastinate Posted May 9, 2015 Report Share Posted May 9, 2015 Why 5? I used the same equation, but I got something like 0.27 kg. Also, how did you draw the graph for the KE of particle B? Ahh that's similar to what my friend got. .5 = 1/2 I drew it exactly like the graph for the KE particle A, with a maximum KE of 0.04 when x=0.

superspeed49 Posted May 9, 2015 Author Report Share Posted May 9, 2015 Sorry guys, can't remember. Was q9 the one of momentum and cycle with Pressure- Volume (im hl tz2). Getting quite confused Reply Link to post Share on other sites More sharing options...
ordinaryguy Posted May 9, 2015 Report Share Posted May 9, 2015 Who did the question on thermodynamics where you had to calc the new temperature of the gas? Did you guys get 500K? 1 Reply Link to post Share on other sites More sharing options...
Sofia. Posted May 9, 2015 Report Share Posted May 9, 2015 Who did the question on thermodynamics where you had to calc the new temperature of the gas? Did you guys get 500K? Yep, I got 500K. Silly of them to ask which process was adiabatic after that question! I mean, I think they even stated it in a later question which one was adiabatic... Thanks for that free point.

But what question is that. Strangely enough I got something around 100K (as if the temperature decreased which at the end made sense as the change in internal energy it tells you to calculate came out negative for me). Or i did a tremendous mistake all along. That's question 7. I'm pretty sure you might have made a mistake, although I can't remember the numbers exactly. Didn't the process go from right to left? In an adiabatic change, that's an increase in temperature. For the internal energy, I got 1510 J.. So very positive! Edited May 9, 2015 by Sofia.

whydidiprocrastinate Posted May 9, 2015 Report Share Posted May 9, 2015 How did everyone find the data analysis question (TZ2) ?? Thought that question was pretty interesting at first, as it did take me a while to get the derivation. The rest of that question was pretty basic though.

Was there a question that asked which one was adiabatic? Lol I remember having to label the one which was isochoric 1 Reply Link to post Share on other sites More sharing options...
