IB Smacher Glau Posted May 11, 2012 Report Share Posted May 11, 2012 I see that no one had a open a topic concerning Physics Hl .. more than 24 hours had passed .. so how was it ?? I didn't mange to get the show that question 1) show that the resistance is 15 ohms is just used this equation emf=I(R+r) but didn't get the right answer also wt option did you pick ?

timtamboy63 Posted May 11, 2012 Report Share Posted May 11, 2012 I got the resistance question, didn't get the show whether the charged particle collides with the sphere.I picked B1 and B4, they weren't too bad at all. 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 (edited) Waw u did the same options that I did .. for the colliding of sphere I wrote that since they have same charge their will be a repulsive force and they move away .. I think I got the first graph wrongly the best fit line many of us in our class thought that the best fit line is always a Stright line but the frsit graph it's supposed to be exponential curve !

timtamboy63 Posted May 11, 2012 Report Share Posted May 11, 2012 No, you were supposed to work out whether or not the repulsive force would overcome the particles initial velocity. Reply Link to post Share on other sites More sharing options...
DeBrogliez Posted May 11, 2012 Report Share Posted May 11, 2012 YeaI found the decelerationAnd hence the stopping distanceWhich was 1.08 mSo they will not collideAnd I chose B2, B4I found them easier 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 How did you guys find it? I thought it was really easy compared to past papers...but I screwed up a lot of question that were worth a lot of marks so I'm kinda worried about the grade curving. btw, I did B1 and B2. Anyone else? 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 guess this year 80 % is a 7 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 What did you put for the multiple choice question (I can't fully remember the question, it goes something like this):What type of EMR would you use to ___ (forgot)___?a) microwavesb) red lightc) x-raysd) gamma rays or somethingIf you remember this question..what did you put?

britney spears is awesome Posted May 11, 2012 Report Share Posted May 11, 2012 @IBSmacher Oh my. I am really screwed then. 80% is your ballpark for paper 1 or 2? paper 1 was ridiculously easy but I really screwed up paper 2 and 3 cause by then my brain was just really toasted from the past weeks of IB exams.

Come on paper 3 was easy wt option did u do but guess we are not allowed to discuss it only after 24 hours !! 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 nope, paper 1 higher level. it's a multiple choice question. 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 paper 3 was okay for the options i did, except I had like a major brain freeze for some questions...one was worth like 4 marks. T___T Reply Link to post Share on other sites More sharing options...
