Here is a copy of todays examination paper. I hope that you all went well! To me, it seems pretty easy, I bet a great deal of people wrote about Solar Cells in the Photocell question and a couple of tricky MC, but no big concerns!

Diameter was 550!

Q2Q was simple. Interesting that all the big core questions came from Ideas. Not very many hard qs, a couple of tricky MC though

re: HSC Physics Marathon Archive Hahaha :) Best of luck for tomorrow mate :) I know you will smash it! :) Pls SMS me when ur out and let me know how you went!

re: HSC Physics Marathon Archive Hahaha, I didn't even read ur question, lol :)

re: HSC Physics Marathon Archive 13.6 eV is ionisation energy of Hydrogen That 12.xx answer Menomaths ends up with would be in eV, would have to convert to J before using E = hc/lambda

Stopping voltage is measured in V, not eV! 1eV = work required to 'push' an electron through a potential difference of 1V From W = qV

re: HSC Physics Marathon Archive That is so evil. That is something I would do.

re: HSC Physics Marathon Archive Yep :)

Nope. The scientist MUST be Australian, currently practicing and you must know male and female!

re: HSC Physics Marathon Archive With these numbers Uy = 40.8 and after 3s, the delta Y is 100m, not 60m! :)

I would upload it, but our chem teachers weren't bothered to go down and get a copy :\ gg If I get one 2mrw, I will upload

re: HSC Physics Marathon Archive (GIVE THEM TIME SUPERSAIYAN!!) ?HARD? CONCEPTUAL MATHS QUESTION A projectile is launched from the surface of planet habibi (pronounced kkkkkkkkhabeebee), at t = 3s and t = 14s, the vertical displacement is 60m. Determine the acceleration due to gravity on...

re: HSC Physics Marathon Archive Well done again, young padawan :D

re: HSC Physics Marathon Archive ANYONE FOR A HARD MATHS QUESTION?!?! A sniper is lying in a prone position such that the barrel of his rifle is 30cm above the ground. The muzzle velocity of his rifle is 800ms-1. A target appears at a distance of 1250m with the centre of the target 1.2m above...

re: HSC Physics Marathon Archive Outline how doping causes holes to be generated in a p-type semiconductor and clarify how they act as charge carriers. USE EITHER THE TERM ACCEPTOR LEVEL OR DONOR LEVEL IN YOUR ANSWER AND PROVIDE AN APPROPRIATE DIAGRAM (3 MARKS)

re: HSC Physics Marathon Archive Well done SuperSaiyan! I was wondering to see how long it would take for someone to account for mass dilation! NOT TOO LONG AT ALL :D

re: HSC Physics Marathon Archive :vcross: Dont talk about Siddy like that! :devil: Question: (3 marks) A proton is fired into an Electric Field at a speed of 2.8x10^8ms-1. The field is provided by a pair of parallel plates with a potential difference of 1kV, separated by 1cm. The...

What really happens.. http://www.hscphysics.edu.au/resource/MagnetRace.flv

HSC wants you to say that due to the slit, eddy currents will be minimised and no force due to the eddy currents will be experienced by the falling magnet, so it will pass out of the tube in the same amount of time as the plastic tube. Have a look at 2011 HSC Q25 and the associated marking...
