Good Work Tommy, seems right :D

Probably Trigonometry :P

More practice questions: :D What comparisons and can be drawn between O and Othello? What contrast is there in O and Othello?

Re: Physics: Difficult (for me) Urgent Question !!!!! Sometimes the question makers try to trick you into using all the data given, when you only need to use a few. Sneaky people! :D

Othello: -talk about techniques (e.g. Characters, Plot, Themes, etc...) O: -Since it is a movie based on a play, talk about the similarities and differences, Camera angles, lighting. Here's a practice question: In the movie "O" how has the director represented the play "Othello"?

Re: Physics: Difficult (for me) Urgent Question !!!!! Its 6m not 6cm, plus it doesn't matter. All's i know is R is proportional to l therefore resistance is 6 ohms P=V2 / R P=1102 / 6 P=12100/6 P=2016.67 Watts wtf???

Re: Physics: Difficult (for me) Urgent Question !!!!! I also don't get why Question A) can be 504W. :( Because: Power:Voltage is 2400:240 10:1 therefore x:110 x=110 * 10 x=1100 watts For Question C) let's assume Power = 504W P=VI 504=110 * I I = 4.58 amps

:lol: Funny way of thinking. Like a sine curve. :lol:

Re: Physics: Difficult (for me) Urgent Question !!!!! A) 2400/x = 240/110 240x=2400 * 110 240x=264000 x=1100 Watts C) Power (W)=Voltage(V) * Current (A) 2400=240 * A A=10 amperes D) 1100=110*A A=10 amperes

Find the x-coordinates of the points P and Q on y=(x-h)2 + k such that the tangents at P and Q have gradients m and -m respectively? is that too hard? :(

y' = lim h->0 f(x+h)-f(x) / h y' = lim h->0 5(x+h)2-3 - (5x2-3) / h y' = lim h->0 5x2 + 10hx +10h2 -3 - 5x2 + 3 /h y' = lim h->0 10hx +10h2 /h y' = lim h->0 h(10x+10h) /h y' = lim h->0 10x+10h y' = 10x Sorry Namu :D

Yeah :D

l would rather watch the original Top Gear, better. :D

Re: Can the school reject you/kick you out from a subject? When you choose subjects you can get rejected. I'm not sure about kicking out, they might give you a chance in Yr 11, probably not in Yr 12.

Pro as in professional study guy Highlighted in Blue: O.o heh

I use the internet, then books :D

1) x2 + y2=4 is a circle with C(0,0) and radius=2 Domain: {xER: -2 <= x <= 2} Range: {yER: -2 <= y <= 2}

That'd be so cool :D
