I agree with most of it except Probability theory.

? Sorry Didnt quite get the last sentence ...,. Yes I got d. My explanation was because if it came in a 3-4 mark question then it says with calculations explain then yeh my answer would be easily applicable, if correct. But then why did the teachers answer c? and the answers say b? and we got...

I must have done a lot of things wrong. i will check my work. But shouldnt the differences in kinetic energy be the energy that is converted to electrical energy? Maybe they took into account the exponential increase in induced kinetic energy over time due to intensity I which is propotional to...

Re: MX2 Integration Marathon Hey does anyone have the compiled copy of all these questions. Rumour was spread that int. marathon question copies were being done?

Hey Eth

Please clarify too.

Maybe the electrons experience a force therefore probably cause a current? And maybe it has something to do with the geometrical properties of a circle and therefore can cause like angular velocity for electrons?

Not sure of this is right but by the projectile formula (v^2-u^2)/2g = d we get v= sqrt (2gd) since u=0. By subbing in values u find v=sqrt (19.6). Now kinetic energy difference in values =KE= KEf-KEi: 1/2 * 0.1 ( 19.6 - 3.8^2) = 0.258. The solution is D?. note the KEi represents the value of...

Wait so how good is 0.99863 mol/L from 3 trials average given the concentration of 0.1 mol/L. I somehow got this. I am alright at calc.

Differentiate? with this they ask you to find this to see the gradient at the point so you can determine whether a sharp point or vertical tangent? And amplitude is the coefficient already before the trig function

Yes. The easier way by algebra is to remeber the domain of the function and instead of the original x value sub in the value provided instead. i.e. instead of sin (x) if provided sin(2x + pi) the let -pi/2 < 2x + pi < pi/2 to find domain and to find range sub in the values of domain found into...

Please show me how to do each one..... yes carrot, as I mentioned I am ok with calculations of moles, ph , molarity concentration etc. just the electrchemistry the oxidant etc. Strawberry by atomic numbers i meant the use of atomic numbers to determine the type of decays that will occur i.e...

Guys in Year 11 I used to find chemistry simple but now I find it confusing especially the multiple choice. Its almost as if all the content disappears from my brain when I do the question. For calculation or equilibrium things its ok, but for things like electrochemistry I find it confusing...

Conics > statistics > harder ext1. And well what would you use combinations and permutations or circle geo or inequalities for ? Conic sections are used for suspension bridges, astronomy, medical imaging, medical, lenses, architecture, hour glass :), navigation, satellite communication...

Re: MX2 Integration Marathon hey sy or carrot, you were compiling this right?

+1 Happened to a friend of mine from Baulkham Hills. He wasnt happy.

Just wondering what you people think about this. Would you grow up to be a kind helpful and understanding person or be a successful and rich person. Please state your views in the poll. This will help me in a way.

HSC. 30% of my last 4U paper's marks was from HSC Questions exactly. But I hadnt done those questions since I had done trial questions. So finish HSC ques.
