Physics Paper 3 2012 discussion (I have the qp)

[svenas]

ok this would be yr mark out of 200

If I take 38/40 in paper 1 (57)
If I take 33/40 in paper 6 (33)
If I take 60/80 in paper 3 (75)

U get 165/200 with these results which is like a definite A*.....coz I think anything above 145/150 would be an A* as this year the paper was waayyy harder than the previous years.....
I got 163/200 and I hope I get an A* as well

I wish all of us get A*...also I'd be happy with A...it's good grade too...
But english I really messed up aloooooooooooooooot in listening....I will be happy if I get an A or B..so happy...wbu?

I didnt take english XD so yeah....I am fine with an A but I would like an A*

do u wanna discuss chemistry? Like on that website like day before?

I don't take ict but if u got the chance to send me the paper of ict(for my friends)...I'd appreciate it..!!

yes FOR SURE

 

[EpicLol]

yes FOR SURE

Pretty sure how much did u think u lost in paper 1 and paper 6??

3- 4 in P1 and 3-4 in P6

I have the question paper ppl, so if anyone has any doubts on how they did on certain questions, then they can post what they remember and I can repost the exact question to see if u ppl got it right

Just post questions/doubts/answers anything about physics paper 3 or 6

what about question 1 ,2 and 7 ????

each lightning stroke....u get 375000W per stroke and since they ask in energy I changed it into J and Im pretty sure thats the only way u can do it.....because if u take 120 seconds then the question is asking for each stroke of lighting.....so Im not really sure.....

Hi I dont think you understood my question, I did it the same way as you but instead of multiplying by one I multiplied by 120 and this is because this was the only time given in the question and it never took 1 second for each stroke. Secondly, the beta particles one, shouldn't the beta particles move in the opposite way as they are electrons and we shud use conventional (which is the opposite of beta movement) Ty I hope u don't get angry because I argue with u

I dont ususally get angry lol....yes the beta particles one I know I did it wrong on the papaer yes that is flow of like beta particles so current is in the opposite direction...., but the lightning one, it cannot be *120 as that is the time interval between 2 lightning strikes....and the question was asking for the energy transfered in each lightning strike....but I see what u r trying to get at....we should ask others......

I'm an "other", I multiplied it by 120 because we don't know how long each lightning strike lasted, so we multiply by the interval as that is equivalent to the total energy of one strike!!!

who said that i tolld you its 1secont i did varient 2....32 which this exam is nothing acoording to that

 

[Abu mota]

Who was talking to u????? Lol this is very funny u come from nowhere to talk as if I was talking to u. Btw in all of the examination variant 1 is usually harder because it is known that the people who do variant one r the smartest

 

[19loko97]

can you please do the same for the chemistry and biology paper 3 if you can?

 

[EpicLol]

I agree that it only give 120 seconds, but it says that is the interval between 2 strikes, not how long the strike lasts, i mean a lightning strike which last for 120 seconds kinda seems unreal....

on wikipedia it says that it takes 30 microseconds exactly for a lightning to strike lol

then we both fail.....

 

[Abu mota]

then we both fail.....

LOL

 

[EpicLol]

LOL

u might be right coz energy builds up in the 120 seconds and then releases it with each lightning strike....but then again the lenght of the strike tells us howmuch energy it posseses as usual....

who cares the exam ended anyway
