sriracha sauce.. alot of it

Re: General Thoughts: Physics shouldnt you talk about losses percentage wise, because the first one was a higher output voltage..energy loss/total output power

20.A calculate energy of photon. using around 10*10^-6m as wavelength. convert to ev get around 0.1eV which isnt enough energy to overcome the band gaps except for A

"x is the displacement" "When is the displacement of the particle zero" hence x=0

i think the units for Q13d) is meant to be hours

OP, for first problem, solving for l in x^2 + lx + 12 = 0 and finding minimum value for l using dl/dx is pretty easy to understand, also works

Q15 a) (iv) using iii) 1<=j<=n sqrt(n) <= sqrt(j(n-j+1)) <= (n+1)/2 let j=1,2,3...n and multiply them all sqrt(n^n) <= sqrt([1*2*3....*n][n*(n-1)*(n-2)...1] <= [(n+1)/2]^n sqrt(n^n) <= sqrt([n!][n!]) <= [(n+1)/2]^n sqrt(n^n) <= n! <= [(n+1)/2]^n

86-91 raw, overall Q1-14 easy, Q15-16 hard

i got 13!/(10!*3!) pretty sure thats right

easy.

its what i usually do, except i finish 30 mins early and dont check because i can't be bothered.

spend ur reading time reading all the questions... MCQ + Q11/12 - 35mins Q13/14 - 50 mins Q15/16 - 65 mins 30 mins check thats what i would do if questions are average, could be different for others

PILOT BPS-GP best pen ever.

i found the 4u HSC paper of 2000 pretty difficult 10/120 lower than my average

82-84

one of the lowest marks u can get is 76. so its pretty easy. Also reverse atar is stupid as it assumes u are equally good at all subjects rather than having strengths and weaknesses.

bump. is 99 possible?
