Re: 2013 HSC physics marathon thank you for that.

Re: 2013 HSC physics marathon haha thank you for the advice :) so which equations other than f=ma?

Re: 2013 HSC physics marathon If an object travelled at relavistic speeds it would experience mass dilation and its mass would increase. As a result of its mass increasing, its acceleration would decrease, assuming net force is constant. If this trend continues, the final outcome would be that...

yes it would be useful.

yeah it will round up.

Re: mola heat of combustion sshhh.

only 2.5 weeks left of school...and 3 assessments..far out.

Re: mola heat of combustion i hope you got the first part of the calculation, that is yr 11 stuff.

Re: mola heat of combustion change in H=m*C*change in temp 4.18*200*change in temp=836*change in temp =0.836*change in temp moles of fuel=grams of fuel/MM of fuel moles of fuel=0.6/60.094 =0.001 Molar heat of combustion=2021 kJ/mol and, we know molar heat of combustion is kJ/(mol of fuel) or...

+1

sequences and series + calculus

our assessment today was a complete joke. the average for 3u/4u kids will be ~90-95 whilst the average for 2u ppl will be 80%

yeah. the only thing that is 'difficult' in geo applications of differentiation is maxima and minima and btw i have first hand experience cos i have an assessment tomorrow too!

lol. do MIF first and then do past paper questions. make sure you do lots of maxima and minima :)

haha i was just joking/trolling with him cos he's a friend :/

alright, thank you. also could you pls just kill yourself? i give you 1/3 for your lack of sensitivity, it was just a silly mistake. just to reiterate, kill yourself. fullysrs/10

i reckon the answer is 6.96*10^10. (and im sure it's without the negative sign this time) Also if you dont mind me asking, which textbook/where are you getting these questions from?

yeah im pretty sure the answer to part c) is -6.96*10^10

wait how do you calculate part c)?

wait is the answer to part c) 6.96*10^10? (btw i havent done the space topic at school yet)
