re: HSC Physics Marathon Archive touché, good explanation

re: HSC Physics Marathon Archive Momentum is the same but the relative velocity would different after the slingshot effect has occurred?

re: HSC Physics Marathon Archive The velocity change of the planet is negligible though, the velocity change of the spaceship is large

the conservation laws are the most important part.... its an elastic collision

Title

Projectile motion is symmetrical (an angle of 80 degrees produces the same range as 10 degrees) so it obviously isn't A or B as the range is the same. If you increase the angle, the y component is increased so the time of flight is larger, therefore C

Isn't that what Pauli did

What are we expected to know for the hsc? Are we even supposed to know that for the hsc? Is simply saying, "Heisenberg developed matrix mechanics to explain quantum phenomena, that is similar to Schrodinger's wave equations, to further our understanding of the atom" in a typical HSC question...

Also when talking about what Heisenberg contributed, the success one textbook talks about some matrix mechanics stuff that he did, what the hell is that? Only ever learnt about him developing the uncertainty principle

would a superconducting iron core reduce energy losses, or since current in a superconductor never dissipates would a huge amount of energy just end up being stored in the superconductor, instead of it dissipating as heat? Or would the current eventually build up to the point where the...

the complex number stuff had to be all graphed on the same diagram right? the z, u and v stuff

low 90's to high 80's I feel sorry for the wanna be state rankers and general maths enthusiasts, that Q16 was a bit weak for them. It was pretty similar to the last Q from 2002 hsc though (and I swear I've seen the circular motion Q somewhere before)

in the 2005 hsc theres this question about how pauli and Fermi contributed to the neutrino and in the markers notes it says many didn't mention what Fermi did. Fermi simply stated that the so called neutral particle that Pauli suggested should be called a neutrino, so that it wasn't confused...

re: HSC Physics Marathon Archive Probably a 3-4 to be honest, you shouldn't have all the description about the function at the start, it is useless for the question where you need to assess how it affects society, not why transistors are now used. That first sentence of your assessment should...

re: HSC Physics Marathon Archive you forgot to add a question so w/e ill add another assess the impact of transistors on society (6 marks)

re: HSC Physics Marathon Archive hmm yeah fair enough. Discuss planck and Einstein's differing views about whether science research should be removed from social and political forces 5 marks p.s: thank god English is over, now I can live in maths and physics for the next two weeks

I need italics to show interior monologue of a non-central character in a creative, will using blue create a distinction from black, when scanning?

Is highlighting the accepted way, as in, the ways marker will recognise italics? Any specific colour they like, or one that show ups better when scanning? Would a thin pink line be ok, or would you have to really highlight the whole word from top to bottom to make it obvious when they scan

Yeah, but when someone is reading it at 1am with a cup of coffee I don't think they will notice a small change of incline (or do they?)

title I guess, how do you make it obvious, if it did italics in blue pen and then rest in black would that make it more obvious when scanned
