I couldnt believe my UAI..I was so stoked SAM: 94.50 (this wasa big enough surprise!!) UAI: 95.35

i thought it was easy and only had trouble with 1 or 2 2 markers and the 4 mark pictorial which i didnt really attempt. but other than that it was easy. and how easy was the hybrid vehicle part? so much u can talk about.

thanks nbenson i couldnt figure it out because i forgot that fundamental ln rule of brining down the power and putting it in front of the ln. thanks heaps. good luck to you as well.

can someone please tell me how to do this question? ( b part ii) An=200000(1.006)^(n) - 2800 [ (1+1.006+1.006^2 + 1.006^3 +....+1.006^(n-1) ] I got as far as An = 0 and rearanged a bit, but didnt know where to go from there. Any help would be great as I may need to know how to do somthing...

i figured it out :) you let the straight line = the parabola in part 2. you make it all = 0 and you end up getting the discriminant you found in part i. the discriminant has to be <0 for it to not intersect the st line. solve x for discriminant<0. i got -6<k<10. i only wish i knew that in the...

part i was easy finding the descriminant how do you do part ii? i ad some i dea but couldnt actually put down an answer. i mey need to know this for extension 1 so any help would be appreciated.

the part before the distance calculation - did it ask to find the mass or the weight of the rod? i think i only found the mass (from the graph = easy)...but didnt time it by 9.8...i timesd it by 9.8 in the distance calculation though. oh well nothing i can do now.

copper isnt a permanent magent. iron, nickel, cobalt are. it is the eddy current's magnetic field that opposes the magnet. the eddy current is produced by the falling magnet. lenzs law.

yeh i didnt know what a bone scan was. i said it was an ultrasound used to measure bone density. and what about the pictures? i said the bone scan was the first, xray second, and CAT scan the third? what did you think? and the seven marker, only had bout 6 minutes, and i wrote about Xray, cat...

YES! they never give enough lines. I was writing as small as possible and went over the given amout of lines by at least one line for every question.

yeh i got between 2 and 3 cm.

but if you put a current of zero (I1 or 12) into the F/l equation you will get nothing as you are multiplying by zero. you have to figure out the force of attraction. since it is a proportional relationship, all you need to do is pick one of the currents that were recorded (i picked the highest...

i thought the exam was great, a really fair exam all up. i didnt get full marks in the big markers on the photoelectric effect, superconductors and the 7 marker in med physics, probably 4 out of 7 for that one. I think i made up for it though. im hoping band 6.

Yes, I am also thinking of doing an engineering/commerce degree. In the undergrad guide for 2007, it says that it is a reduced engineering program, omitting general education. What does that mean? Can I still do the structural electives i.e. specialise?
