[muhammadali233]

Was the paper to easy or i did all wrong ?lol

ho did it go? Question 2? Kitne marks kateen ge?

kafi ajain gay

 

[rabia10]

I have lost eight mrks

 

[Faiqa Nadeem]

I hope the grade threshold is very low because of question 2 :/

 

[Faiqa Ahmad]

What did you get in question 2?

 

[buckle_crackk]

will probably get 2 marks for question 2 had the rest unattempted

 

[muhammadali233]

distance and speed could have been calculated through area under graph or by equations of motions .......equations of motion were given on the second page....

 

[farhan141]

I found q.2 pretty easy except the last graph lol. But I messed up in Pressure kinetic theory, touched ldr graph with xaxis and silly stuff like that... Almost losing 20 marks .

 

[Jattin Singh]

Guys what was the change in momentum?

 

[Faiqa Nadeem]

I almost lost 18-20 makes because of stupid silly mistake as well for the change in momentum I was getting 1.66x10^-23
Idk if I remember it correctly
What was the answer for the frequency on the last part of the waves question? In GHz

 

[Jattin Singh]

10.7

 

[Sadia Ahmad]

What did you get in question 2?

do you know the answers to question 2 ?

 

[rabia10]

Yup its correct

 

[Llama2617]

10.7

Isn't it 1.07*10^19

For distance i did 1/2 x 9.81 x 2.5(sq) + 1/2 x 9.81 x 0.5(sq).. Did anyone else do that?

 

[Amandaissocoollike]

For distance i did 1/2 x 9.81 x 2.5(sq) + 1/2 x 9.81 x 0.5(sq).. Did anyone else do that?

I don't remember the values exactly but yeah I did the method like that, sort of. What was your answer?

 

[AbdullahBShakeel]

I got 31.3 sth.. But some of my friends used time as 3(sq) and they got 44.. Which one's right..

 

[Faiqa Ahmad]

I got 31.3 sth.. But some of my friends used time as 3(sq) and they got 44.. Which one's right..

I got 44 too :O

 

[AbdullahBShakeel]

I got 44 too :O

No Faiqa i just got it.. We were supposed to do 1/2 x 9.81 x 1.25(sq) + 1/2 x 9.81 x 1.75(sq) because ball is at top at 1.25s not 1.5 :|

 

[Amandaissocoollike]

so 44 is wrong? i got that too
