re: HSC Physics Marathon Archive ohh i see, astrophysics seems interesting, but Q2Q still the boss :D

re: HSC Physics Marathon Archive what topic is that under? (dont remember being in the core)

re: HSC Physics Marathon Archive @astro cx60x60x24x365

I wear gunnars (computer anti-glare) while studying... Prob study 10-14 hours a day definitely notice my vision weakening throughout day (likely due to eye stress)

Re: HSC 2015 4U Marathon Dayum, havent learnt inverse yet... (is this harder 3u?)

Alright, i'll note that down :D Thanks Yun (and integrand)

re: HSC Physics Marathon Archive Yeah it was 192 (was tossing up between either 192 or 300, forgot that relativistic time is slower)

no, i think u misinterpreted. you dont score marks for irrelevant info, nor do you lose marks (but integrand says otherwise for long responses). you score marks if you meet the marking criteria but then again, i'm just a noob at these hsc thingys

lol, you dont 'lose' marks for putting irrelevant info. you only score marks... (or so i'm told) the lesson is: pour everything you know onto that piece of paper, ggwp (too late now, haha)

->justification as to why it's a pollutant ->back up reason for incomplete combustion (show that insufficient oxygen on the left side etc.) ->explanation as to how to monitor energy,oxygen,environmental impacts etc. ->costs and how it affects society if not monitored (3 of these should do for...

Can i have a copy of your notes. Wallah i will cherish it.

re: HSC Physics Marathon Archive Ahh dayum, didn't read that last part (sneaky...) Then i reckon it's 300s (second guessing myself) Edit: It's 192, shown by integrand below

re: HSC Physics Marathon Archive I'm thinking 240s? (will show working after you say it's correcto :) )

I have not read what you've previously said, but that cpu is def overkill. But if you've got the money and cbb changing last minute (since cpu requires a good extent of research) then the cpu is fine...

re: HSC Physics Marathon Archive W=Energy (kinetic i think) E=m(0)xc^2x(1-v^2/c^2)^-0.5 =9.109×10^-31x(3x10^8)^2x((1-0.98^2)^0.5-1) =4.1197x10^-13J Edit: Forgot two negative signs...

re: HSC Physics Marathon Archive OK: given g=9.8, G=6.67x10^-11 and Mass of earth=6x10^24 and let m2=1kg (in this case) <-sub in w/e value in the exam g=Gm1m2/r^2 r^2=(6.67x10^-11x6x10^24)/9.8 r=6387.1km

It's kinda gey, thas all. No but srsly, where do i disable the rep, it's fawked mate.

re: HSC Physics Marathon Archive F(g)=GM1M2/r^2 G=6.67x10^-11 m^3kg^-1s^-2 M of earth=5.97x10^24kg edit: brb, i misread question lol

How to disable rep (I've read http://community.boredofstudies.org/faq.php?faq=vb3_user_profile, can't find "Edit Options") I have no interests in any Industry and its compulsory, wot?

Re: HSC 2015 4U Marathon Hmm, I'd like to know that last line of Integrand's proof :P
