OMG! Physics p22!!!

[wasiqss]

and for the last part of photograph i wrote...that as resistance is not negligible...air resistance wuld increase with sped...resultant force wuld decrease and so wuld the acceleration..and hence the new image would be below the initial position....i hope that is right!

Nahh distance covered per unit time decreased ,hence in the time given,ball wud cover comparatively samller distance,and new image wud be above

i wrote that in the last secong:|...i thought that acceleration would be constant for any mass so i wrote there will be no change...im pretty sure this is wrong...and what did u write about how to conserve mass-energy thing in the last question??

and If every other person loses 10 -20 marks...the grade threshold might drop to 38... thats gr8!!!

@wasiqss: wasn't it distance kept consatnt as far as i remmeber!! and they asked for the time taken..to travel the same distance...so that is y it asked for the position of photograph... :?:

 

[faheem92]

What was the answer for last part, was it -- x 10^6? And why was mass conserved? Paper was too tough and lengthy!!!!!!!!

 

[intel1993]

wat were the times for phiotograph question??

no it wanted to asked whether it travelled the same distance in Our calculated time,

 

[wasiqss]

wat were the times for phiotograph question??

.4 and .03

 

[gerrard]

correct

 

[wasiqss]

guyz dun worry i ll keep grade threshold by July

 

[gerrard]

???

 

[wasiqss]

what

 

[intel1993]

yes ashhadazam is completely rite....it doesnt ask for the position........w ehave tow rite about quatlity........it qill get more clear...as decceleration...so more time hence more clear the photo.......

 

[hamizahmed]

yar jo b ho, paper ne bja di full

 

[ashhadazam]

yar jo b ho, paper ne bja di full

Haah :mrgreen: :mrgreen: :mrgreen:

 

[hamizahmed]

yar CIE walay pagal hogaye hain, pehele phy p1 itna mushkil dia, phr prac of 34 bhe mushkil aya and now this... Mra phy ka A gya. Pakka

 

[ashhadazam]

Chem p2 was the best so far, i think -.-

 

[hamizahmed]

I agree ashhad

 

[hamizahmed]

ye CIE walay apni auqat bhulgaye hain. Ye hum pak he hain jin ki wja se in ka board chal rha hai.... Warna agr pakistani ye paper na dain to in ka to diwalia nikal jae. And still ye hmare sath aesa sulook karte hain. :evil: :evil: :evil: :evil:

 

[DDGAL]

i hav lost 20 marks...damn i cant think properly nemore.... kutta CIE!!! i just hope the grade thresholds will be LOWWWWWWWWWW!!!

 

[gentleman]

what came for the kinematics qn??
