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.
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
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...
