*using g=10m/s and v=170m/s derive: y=-x(1+tan)/5780 + xtan *sub y=1.5 and x=100 1.5 = -10000(1+tan)/5780 + 100tan simplify and rearrange: 433.5 = -500(1+tan) +28900tan 500tan - 28900tan + 933.5 = 0 *let u = tan 500u - 28900u +933.5 = 0 u = tan = [28900 28867.68089]/1000 tan =...

oh yeh it is too...i always thought Cl was above F...=|

you mean the further to the right =) and why wouldnt chlorine be more electronegative than fluorine? i guess you can say tetrahedral? or pyramidal? like the substructure of diamond...

3)*for it to be limiting sum |r|1 [where means less than or equal than] r = (sqrt3)tanx |(sqrt3)tanx| 1 *i(sqrt3)tanx 1 OR ii-(sqrt3)tanx 1 itanx 1/(sqrt3) x = pi/6 ii tanx -1/(sqrt)3 x = 5pi/6 therefore x = pi/6 or 5pi/6 4)a)as t approaches infinity ke^(-1.5t) approaches 0...

1)3m+n =6 ------------- m - n 3m+n = 6m-6n 3m = 7n m:n = 7:3 2)a)a=d/dxv/2 a = 2-x a = -1(x-2) a = -nx therefore it is SHM centre : x=2 period : 2pi/n = 2pi seconds amplitude : v = 12+4x-x = 0 (x-6)(x+2) = 0 x=6, -2 therefore amplitude = 4units c) wat do you mean...

the first one is right...in your second answer you're assuming that the rate of depletion is constant, which it is not [its exponential, remember]

hahah yeh you're just applying a formula =)

ooops sorry i got the cos and sin mixed up..hold on i'll fix it.. DONE!!

*n=pi/3 , a=8 , x=5 x = acos(nt) v = -ansin(nt) a = -ancos(nt) => but x = acos(nt) a = -nx *sub x=5 a=8 n=pi/3 5 = 8cos[(pi/3)t] t = 49.000490121 seconds *sub a=8 n=pi/3 t=409.000490121 v = -ansin(nt) v = -(8pi)sin[(pi/3)49.00490121] all divided by 3 v = -6.5cm/s *sub n=pi/3...

its the latter =D and i just remembered..i finished reading harry potter and yes he does say that chocolate is good =) and yes i care abt my hsc!!

I think 2U was relatively easy... anyway i got 3 left: 3U, geography and physics..

Module A [Experience Through Language] : Strictly Ballroom - film Module B [Close Study Of Text] : Navigating - play Module C [Texts And Society] : Bruce Dawe - poems

there are quite a few people, if not then a lot, who do 12 units..just for backup..

Sorry not sure abt Q2...

1)a)* x = Vtcos and y = -(gt)/2 + Vtsin *at t = 1 and taking g = 10m/s...and x=20 and y=12 sub: x = Vtcos => 20=Vcos y = -(gt)/2 + Vtsin => 12= -5 +Vsin *do simultaneous: => V=20/cos 12 = -5 + 20tan tan = 17/20 = 40 22' [to nearest min.] V = (20)/(cos40 22') V =...

try to put all that behind you...focus and concentrate...try to understand the concept, not just the formula, as it makes things more easier... calm down..do some past papers if you have any, and any Q's you cant do, revise that topic..

fail english as in failing to meet course requiremets...i think its your overall assessment..not sure im a little iffy abt it...someone care to clarify?

hahaha thats right...no one gets 20/20..its only 19/20 like in one of my previous assessment tasks

Why dont you study then? I'm lazy but i still study, even if it's the night before...it does help a lot
