When i told them that I got 99.00 UAI the reaction was simple. "Good job" and nothing has changed :P lol!

UAI : 99.00 realm: smolderthorn class: warrior level: 65

I said we deconstructed the sample cooktop and verified that they were the coils and pans and I also said that i went to an amusement park to ask the technician how the braking system works.. Alrite i did totally different stuff lol! am i wrong??

1. you are correct 8. nope there is still changing magnetic flux since u push the switch. hence (c) it will hav current induced for a short time then 0 no magnetic flux 9. def B copper induces the current flowing opposite direction hence slower.

oh ya haha 14/15 :p i still dont get it.. can u show it mathematically? thx@!

Lol!-_-;; i got 19/20 in this mutiple questions but i got q1 wrong -_-.... omg.. I thought the range depends on both the initial speed and the time of flight.. am i wrong??

for part i I compared with bubble sort, and said that they both use comparison in their sorting, but bubble sort would compare each adjacent items for all the items. and a little bit extended from here and for part ii since i could not understand the sorting method. What i did was...

That's what i thought too. and all my class put b for dat question! One of them is aiming for at least top 5 in the states... Well I re-checked the book, and i still think b is a right answer

according to the book, needs are often broad, and not specific, whereas objectives are the essential requirments that are often specific. ?

7. a???? I am definitely sure it's b isn't it??

Oh!! Thx..!! i feel better now then;; lol! coz i thought if i screw 3unit maths it affects just my result in 4unit:p Well thx for quick reply!

Is that mean? that my 3unit mark will affects just 'MY' 4 unit scaling?? or apply to all the people in 4unit?

Is here any 4unit ppl who screwd 3unit? I am projecting around 95~100/120 in 4unit However I totally screwed Q7 in 3unit paper.with 1 mark off from question 3 so about 75~78/84 7(a) omg -_- i can't believe that i could not do it..i finished all the exam in 1hour and spent about...

By the way for Q7a. ii) i just wrote down dr/da = da/dt * dr/da and therefore dr/da = 0.02 * dr/da but not caculated coz i could not do (i) would i get ANY mark for writing this down??

My answers are all same except for the question 7(a) coz i could not do it.. omg althought i am first in 4unit and got like 92in trials...suddenly my mind was blocked at that question...I feel so bad that i missed easy stuff.. otherwise, most of them are same and the one with x^2-lx+12=0...

Lol dont be sarcastic! Lol I would say.. If your get 70/120 raw mark. considering this year was harder than 2004 u will probably get Band E4 40/120 will bring u up to Band E3 for a sure coz one of my friend got about 50 last year and ended up with 84

When frictional force ranges from -uF to uF Show a max speed v at which the particle can travel without slipping up the track. v^2/Rg = tanx+u/1-utanx This is a direct question from 1995 HSC I hav answers..but it's not really clear to me.. Coz..i thought, to calculate the speed that...

umm.. sin 30 = r/1 r = 0.5 m = 0.5 Tsin30 = mrw^2 (1) = 0.5*0.5 *w^2 Tcos30 = 9.8 * 0.5 (2) for (1) T = w^2/2 for (2) T = 9.8/root3 then u can find w (angular velocity) rite? by solving T Then just Period = 2pi/w If i am wrong..plz correct me :d

in drawing graphs... if we are given an original function.. when we draw 1/f(x), do we need to draw an original function as well? coz hsc solutions hav dotted lines indicating an original function.

Can they ask projectile motion questions?? a syllabus has kinda projectile motion (but it's not really clear) and i never seen projectile motion in 4unit b4.. another thing is a monotonic increasing function..somehow it's not really clear to me.. monotonic increasing -> a gradient...
