DeBrogliez Posted May 11, 2012 Report Share Posted May 11, 2012 I was screwed in paper 1 I didn't know what to interchanged the position of the magntic field and force in the mass spectrometer You mean the question about region X and Y? If I remember correctly Region X: Electric and Magnetic Region Y: Magnetic only Reply Link to post Share on other sites More sharing options...
IB Smacher Glau Posted May 11, 2012 Author Report Share Posted May 11, 2012 you guys are talking about different time zones, I think.Dude it's written in the tittle TZ2 FTW Reply Link to post Share on other sites More sharing options...
IB Smacher Glau Posted May 11, 2012 Author Report Share Posted May 11, 2012 I did many mistakes in paper 1 I am really sad about that what question also guys you found tricky in paper 1 ? Reply Link to post Share on other sites More sharing options...
DeBrogliez Posted May 11, 2012 Report Share Posted May 11, 2012 The question about thermodynamicsFor the first part I chose isothermal (since it is thermally insulated)And for the entropy, both unchangedBut I'm still unsure Reply Link to post Share on other sites More sharing options...
britney spears is awesome Posted May 11, 2012 Report Share Posted May 11, 2012 I did many mistakes in paper 1 I am really sad about that what question also guys you found tricky in paper 1 ? the one i posted before about the EMR waves... what did u put?

IB Smacher Glau Posted May 11, 2012 Author Report Share Posted May 11, 2012 The Rms question was take away I answered it in seconds ! .. their was also the graph of N(Change in magntic flux ) divided by time the gradient of this curve give us the emf their was a question about this as I remember Reply Link to post Share on other sites More sharing options...

I just vaguely remember these questions. For the rms one, what did you put?The question about thermodynamicsFor the first part I chose isothermal (since it is thermally insulated)And for the entropy, both unchangedBut I'm still unsuredo you remember what the question was to spark my memory?

IB Smacher Glau Posted May 11, 2012 Author Report Share Posted May 11, 2012 The question about thermodynamicsFor the first part I chose isothermal (since it is thermally insulated)And for the entropy, both unchangedBut I'm still unsurehaa dude are you sure ya a think it was question 11 and 12 .. I said it's adiabatic since no energy enters and leaves the system ! and the other one the entropy of surround is always increasing Reply Link to post Share on other sites More sharing options...

I said it's adiabatic since no energy enters and leaves the system !and the other one the entropy of surround is always increasingI dunno I chose isothermal because the temperature is constantAnd for the entropy there was no "increasing"All options were either unchanged or decreasing Reply Link to post Share on other sites More sharing options...
IB Smacher Glau Posted May 11, 2012 Author Report Share Posted May 11, 2012 yes it's 40 volts but their was a werido question about double slit principle do we even have that in the sylllbas I choosed 2 and not sure Reply Link to post Share on other sites More sharing options...

If you are referring to the question about two white fringes and three dark fringes between them; then yes its 3 lambda. Reply Link to post Share on other sites More sharing options...
DeBrogliez Posted May 11, 2012 Report Share Posted May 11, 2012 The best fit line is it supposed to be a straight line always ?No, I don't think so!You're asking about the data-analysis question?I drew a curve that connected the data pointsAnd for the next question to prove the hypothesis is incorrectI multiplied the coordinates of the points to show that they are not the same for all data pointsIs that what we are supposed to do to prove it?

arra Posted May 11, 2012 Report Share Posted May 11, 2012 (edited) The Rms question was take away I answered it in seconds ! .. their was also the graph of N(Change in magntic flux ) divided by time the gradient of this curve give us the emf their was a question about this as I remember40 VoltsNo. The axis was to the power of -3, so it was actually .04 volts.and for the wavelength one I'm pretty sure it is 4 lambda.The one that I found reeally tricky was the force diagram. I initially had selected C, where the normal force and reaction force were equal. However, the actual answer is D, where the reaction force is less than the normal force. Because the Force at an angle is resolved and added to the reaction force to become equal Edited May 11, 2012 by arra Reply Link to post Share on other sites More sharing options...
