Emailed you..... MUCH APPRECIATED!!!!!

BUt higher frequency --> greater energy per photon and therefore more energy per unit area i.e. greater intensity (whihc is power per unit area)..... so I really dont see how u can say changing the energy of a photon doesn't affect the instensity of the emr..... or do I have it all wrong?

In the Excel book it states "Intensity is independent of photon energy". Taking intensity to equal power/area, doesn't an increase in photon energy mean more energy and hence more power per unit area? Thanks in advance

Probably a stupid question but where are all the residentials held for philosophy 2010??? Is it the university of New England or some other place?

wow, congrats guys, amazing achievment.... i've heard rumours that usyd is actually making undergrad med more accessible for 2010, has anyone heard of this and does anyone have any info?

bloody amazing.... for me: 3u maths - 97 4u maths - 97

lol, with that combinations q6, i had diagrams, colour codes, captions, the whole lot! only worth 1 mark :( spent about 5 mins, could have used it more wisely

niceee, with the first part of 7ci i just showed that angle PSR = phi - theta and then said that since its an angle its >0 therefore phi>theta, is that valid?

sqrt(h(a + h))??? i just did it and got the same answer

im pretty sure ill get 75+ with max at 80/84 That tank q (5b) screwed me for some reason :( Was the max value of theta sqrt(a(a + h)) for q 7bii? was 7cii sqrt(ah)? also, could someone please explain why if P is on T, theta is max

Woops, the particle is moving along the outer surface of the cone... im so blind

cambridge q4a excercise 7.5(Theres a particle performing circular motion on the inside surface of a cone): The worked solution has the reaction force pointed outwards from the cone and the answer in bob reflects this. I thought the reaction force opposes the force the particle applies to the...

just got it back 107/120 over the moooooooooooon!

lmao, i spent ages (about 7 minutes) trying to simplify my sin and cos soup, to then realise the t method which got me the answer

I really hope it was 2 because i came out of the exam asking eveyone what they got and they all said k = 1
