General paper discussion

[Saad Mughal]

i wrote that he could draw a speed time graph for the journey and calculate the area under the curve...Simple as that..and i asked my teacher for further assurance and she said that it was right..THE ARGUMENT ENDS RIGHT HERE AND NOW..AINT I A GENIUS..

 

[ijlalm]

what u lolling about eh??

 

[Saad Mughal]

what u lolling about eh??

You're method. How can he plot a speed-time graph when he needs DISTANCE to calculate the speed?

 

[Saad Mughal]

abay yaar speed pata thi distance time graph bana leta araam se bagair mehnat kiye..Why the hell does he want to measure the distance anyways..What will he get from it..

If he knew the speed then he obviously could have just traveled to school, noted the time and used Distance = Speed * Time.
Khair, don't worry. CIE is very lenient, they've accept any logical method I guess.

u mean mine's right?? if yes....YAY!

BTW paper kesa hua??Pretty easy huh??

Yeah you can say.

ALHUMDULILLAH zabardast hua. Expecting full. INSHA ALLAH.

I am expecting full in Chem and Phy. In Bio I messed up that diagram part.

Saad Mughal. Longest Measuring tape isn't even 200m lol, how can it be 300m. I think our answers are correct, the ones who mentioned the speedometer, watch, or trip distance device.

Justus Roe, a surveyor and tape-maker by trade, made the longest tape measure in 1956, at 600 feet (180 m)

i totally did the same...I took only a measuring cylinder with an initial volume of 20cm3 and noted the value as V1.Then i filled the bottle up to its brim and poured its contents in the measuring cylinder and noted the value as V2..To find the value i wrote V=V2-V1.

tht is correct.............however writing 35-40cm3 is better.............. but no marks will be deducted..ur ans is perfect...

a trundel wheel is much more suitable as compared to a speedometer......or watch or trip distance device you knw....

 

[thementor]

well we can all expect at least 25-26 out of 30 marks.....and hopefully full marks...inshallah

What was the answer to the question saying if u=v then calculate from the graph focal length if f=u/2 ?

 

[Hamza Hameed Khan]

Can there be an alternate answe to the question in which they asked to measure the volume of he cap ?

Never heard of it lol so..... I think our method isn't wrong.

You had to take the reading where the value of u=v. It was dependent on the curve of the graph so people got mixed values. I got 19.8 so divided by 2 and answer was 9.9cm.

I don't remember any but if you wrote something else then share.

Listen if my curve crossed the space of the graph that they gave us by 1 mm, will I be penalised for it :s cause everyobe I know only took less than 75% of the graph paper to draw their curve (which usually leads to a loss of marks)...so yeah what was the better approach?

 

[AhsanAfzal]

u wrote u=45.1 it should be 15.1. it was a common mistake
