re: HSC Physics Marathon Archive redid part 2, got 2.87 x 10^11 m (same as psychotropic). I realised i didnt expand the perfect square properly

do you mean sub P (t,y) into the parametric eqns x=t and y=t^2/k? That wont work for y; you must first show there is a relation between y and k. I think pythagoras is the only way to get a relationship between y and k, since you are given the triangle is right angled. It doesnt take that long...

Bio: hopefully transgenic organisms, also they havent asked evidence for evolution for a long time or maybe a long response of antibiotic resistance Chem: impacts of AAS? , dont think they will do acidic oxides as its been asked many times and the questions are too repetitive, Phys: space...

^It seems like you are answering the question " Explain why we continue research into artificial blood? " you havent really explained how artificial blood has contributed to our scientific knowledge. You could say artificial blood has provided a more comprehensive understanding of the role of...

re: HSC Physics Marathon Archive and is 2, 1.16 x 10^11 m from Saturns centre

re: HSC Physics Marathon Archive is 1) 1.03 x 10^-3 N towards Jupiter's centre

wow do people usually get high 90s in 4u?

What are the top marks people (i.e state rankers) get in 4u out of 100. Also do many people get over 90 raw (or 110 raw for exams before 2012)?

Re: HSC 2013 4U Marathon let k be a real number; k>=4 show that for every positive real number b, there exists a positive real number a such that 1/a + 1/b = k/(a+b) Its from HSC 2010

hopefully 35-38, was hoping for 40 but didnt study AOS much in comparison to modules.

it might affect your use of the words effect and affect :p Only the performance of your cohort will influence your atar

sadat, atwood or keating would be nice would cry if pearson

In the HSC can you quote the triangle inequality theorem

you'd need a REALLLLLLY DENSE medium for light to travel at either answer

Deane seems to basic, theres limited analysis that you can have. Also if 30000+ people writing about Deane will probably make all the essays seem similar. But this is just my opinion. There is always a possibility he might be asked.

what if two people just happen to have similar essays? how will they decide if this was due to plagiarism or not. There are only limited points and useful quotes you can get from a text

^ last yrs projectile was pretty good, but most others tend to be basic. Maybe this year they'd ask for a projectile on another planet to keep things fresh !!

^ Thanks for your great advice. I decided to stick with Structure 1 as my analysis for poem 1 is better than the other poems. Also i only have about 3-4 sentences on poem 3 and thats inadequate for a whole paragraph. +1

I hope 7marker is on space re-entry or potential for future space travel due to relativity. I wonder what prac they will ask; probably magnetic levitation or demonstrating motor effect/induction motor. Also hope there is a long response about technology/advances in physics. Hope theres not a...

Shouldnt you know. You're the definition of a recessive gene.
