thank u so much! ill keep that in mind

ah.. so the point of inflexion means there won't be two linear lines joining between t=1 and t=3 but instead a parabolic shape?

the question is q7 biii from 2005 paper

hey thanks i understand all that but just dont know why the answers got it as curvy rather than linear... and yes its a a/t graph not d/t

nope if you do 4u, your 2u will not count at all

can anyone explain the relationship between v/t and a/t curves? i know to get from v/t to a/t you need to differentiate but e.g. one part of the v/t graph is parabolic (decreasing) i.e. y = x2 and differentiating this gives 2x which is linear. Now, why does the answer give a curve graph rather...

probably

thanks all, but namburger you're the man! :)

the shape of a distance vs. time curve is determined by the velocity vs. time relationship. why is that: when the v/t relationship is linear then d/t is parabolic? how do you know whether its concave up or down? when v/t is constant, d/t is linear?

thanks

this is part of a question but you dont need any other information to solve it since t is on both sides wouldnt they cancel out and hence we wont be able to find t??

how do you solve for t: 14000e0.09t > 20000e0.03t

they will get 0, its in the rules and procedures by BOS

How did you utilise the quotes given?

you WILL be punished if you do more than one text if they ask for only ONE! thats like not answering the question

If you topped the state in one subject, would it contribute 100 points to your total of 500 points in determination of the UAI? just wondering

- effect of concentration - nature of electrolyte - nature of electrodes my notes are really confusing me lol, so can somebody give me a brief summary please?

yeah you're right, i skimmed through the 2007 paper and thought i saw 'major segment' when it is indeed 'major sector' :)

lol agreed 102 aligns to a 93 is quite good
