Physics paper 6 2012 + chemistry paper 2 2012 discussions

[wooowooowoo]

thank you that really helped me

and by the way who isn't sleepy here guys
i feel that my eyes are burning

It's actually mid-day in my Country so it's not the right time to be sleepy :/

Mark the centre of the cylinder, measure the cylinder.
After the measurement, place it on the metre rule. It should cover up the area we measure (for eg. 2cm)
So it'll cover the area between 8 - 1o and or 9 - 11 and so on..
If length of the cylinder is 2 cm, make sure to place it at 9 cm and so it ends at 11 cm, being 10 in the middle.

^ I'm sleepy, tell me if you dont understand the explanation

I get it. Sort of. I feel kind of dumb now; thanks!

Wa
Wait , u already did Paper 6 Chem. ?! how was it ?Was it hard !?

it was ok

 

[MERIHAN]

first i want to ask a general question :

what is the range of values for which we can say that it is within the limit of experimental accuracy ??

Q.2 http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Physics (0625)/0625_w10_qp_63.pdf

in this above link of paper can someone explain me that
===>why in the 1 question we are saying it is directly proportional when the line is nt coming from the origin ?

===> in the last question ( 5 c) can some plz give me a sample answer
=====> apart from that sometimes in the spring question they will mentioning some variables in one markscheme and for the same question in anotherpaper the markschemes will not have that point ! so how can we decide which variable to write or not !!!

THANKS IN ADVANCE TO ANYONE WHO WILL SPEND SOME OF THEIR PRECIOUS TIME TO HELP ME

 

[Sara_Hassan]

Questions do get repeated in chem ryt??

 

[Sara_Hassan]

hey does anyone need more notes or are those enough just asking because i need to put on some chemistry notes on by today because we have it on Wednesday and there will be no time to study so i said it would be better if we started chemistry by today afternoon as i think that physics paper 6 should be fine with u by now (if not i won't do any chemistry today)?If u are ok with it plz say so.

yea that'd b great!!

yeah it is sometimes weird un the markscheme
one time i solved the same questione in different variants the answers for the question weren't the same i.e. not all of the points in the first variant 's mark scheme were said in the second variant and that is weird and i don't know what's the reason for that

i really hope these resources help u all Wait for more and more and for paper 6 discussion. Then i will start putting chemistry notes paper 2 !

thanks for the notes really helpful may Allah reward u for this....

thanx

ok when they ask u for putting pins on a ray they must be 5 or more cm apart in any place on the ray but 5or more cm apart if they ask u whydo we view bases of the pins u say that "the pins may not be vertical " if they say how to increase accuracy of ray diagrams then just say
use more pins
keep pins further apart
view bases of the pins that is all hope it helped

thanks alooooot
ya'll are awesome.

MARK THE CENTRE OF THE CYLINDER WITH A MARKER AND MOVE THE CYLINDER ALONG THE SCALE UNTIL THE MARKER POINT TOUCHES THE SCALE.

Question 1, part b), How to make the graph for such SMALL values!?!?

 

[Zico Sakr]

plz any one here can help us !!!

someone told me that they can take reasonable answers that aren't written in the mark scheme
but i don't know if this is true

Guys after 4 hours the chemistry notes will be posted ok

thx a lot....every 1.....may u all be able to do ur xams well...im sure u can bcz u guys always help us by posting wonderful stuff here

 

[hasini]

guys plz tell me when are u finishing paper 6 solving and studying so that i can start posting chemistry notes paper 2

hmm...friend ,did u post ur chemistry notes here???
