Okay now its like tomorrow's paper is going to be more about luck than knowing Physics. What the hell :/

ashiqbal.....how about if we attach the newton meter at the end of the spring and then use our hand to pull the string increasing the force slowly, i mean we dont really hav to use the weights, ryt? wud tht be a valid way??

how wud u measure the amout of force (the MAGNITUDE) u r using to slide the block?? for that u need a known wight or a weight attatched to a newton meter so that u know how much force resulted in moving the block

yes it would be valid! i was almost going to post the exact same method, but i saw better answers, so i didnt!

take rule and fix in clamp stand(vertical) and make sure 0 mark coincides with bottom and place iron clips take magnets one by one notie down no of clips attracted and to what length attracted. repeat for B. one with most clips and attraacted to furthest length wins.phew

perfect

it said power supply if made battery 2/4 if power supply 4/4.

which year? i dont think that they would cut 2 out of 4 marks for one wrong symbol!

perfect

thanks.i got it after doing 8 years

To be frank! I've read your name so many times of XPF that if i meet you i would rather call you ashiqbal that Ashhab Iqbal!
Y u be so addictive XPF?

how much energy will be required to convert 1kg at 1odegreeC into steam???
c (ice) = 21ooJ/kgK
c (water)= 42ooJ/kgK
lf = 3.36*10power5 J/kg
lv= 2.26*10power6 J/kg

Ok Allah Hafiz peeps...Hope you all do good and we all get straight A*s InshAllah Though Im still worried abt my preparation but anyways BEST OF LUCK to u all

 

[MustafaMotani]

plz answer Q4 (a) part....

put some paper clips over plain paper and use magnet beneath to move paper clips from one end to another end... one who could pull most is strongest

no they actually cut a mark for it but another mark is cut for wrong symbol as it says 2 correct 2 marks 4 correct and others 4 marks

An immediate alert to All People prepared for tomorrow's exam!
How many past papers should one practice to be confident tomorrow?

 

[Tuba noor]
