i got 7798.76

seems a bit high, hope it is tho

the one where the satellite was lifted 200km above earth radius, i did v =root/6.67*10^-11 * 6*10^24/(6380000+200000) if i recall correctly, so one line

u can, i did that and got his answer, i got 4.2 *10^7, do you know what u got

oh alright, do you know why the one im thinking about was worth 3 marks? you literally do it in one line. For that 6 marker did you talk about how the planets are attracted by the sun and orbit it and stuff

sick, i got this and i did the other formula, v^2 = u^2 + 2 (a) (s), im guessing we're right cause we used different formulas and still got the exact answer. Edit: I got 4.19 so ~ 4.2 actually

for this question did you have to equate these two? it wsa 3 marks and i did it in 1 line with v=root Gm/r

there was dat 6 marker, 3-4 marks projectile, 5ish marks gravitational potential energy thing, seemed like a lot of space for me.. too much

does anybody know if my reasoning that the electric circuit wasn't closed (that 2 cm gap) means electrons cant be liberated from cathode and accel towards anode? i wrote that + electrons are - charge so its deflecting wrong way

ye good job bruh. how did you find the rest of the test if you were unsure with that one?

a btw, did anyone talk about the circuit not being closed in the electron deflection one? I dont know if thats right

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! What do you reckon the 5/7 marker gonna be on?

Awesome! What did you get to do?

re: HSC Physics Marathon Archive fml, my worst section by far...

re: HSC Physics Marathon Archive 1-2am, need a bit of beauty sleep tonight btw, is there 10, 15 or 20 mc for physics? some papers have differing amounts

you mean perfect weather to describe my mood

re: HSC Physics Marathon Archive how would this be done?

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! Reckon there will be a big question on MRI? It's pretty hard to remember mri compared to the rest

Sure but it's about the demand for labour too. I was always under the preconception that there's less demand for comp field than commerce field (haven't researched but I'm assuming that's the case)

Are you sure about that? I always thought it was the other way around o-o. edit: by compsci/commerce i meant a double degree hehe
