HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

[sammykhan123]

it is 500

u and ur friends have (lambda)/4 instead of (lambda)/2

it was obviously 500...lamda/2.......

How did u ppl gt d tension in d string nywy??

 

[syaukani_93]

If u forgt 2 change r to m in the uncertainty part, its ok...u will still get d right ans....as error R/R so the 10^-3 will cancel out!!

but since i got wrong for the value of C , when i multiply it with the sum of the fractional uncertainties to find uncertainty of C , my answer will be wrong right ?

Boo yaa!!! ^__^

T= mg sin {angle} + frictional force

I think ecf may be considered.

 

[syaukani_93]

I think ecf may be considered.

i hope so thanks anyway .. what is the explaination for the difference between KE and PE in question 2 ?

 

[gary221]

Absolutely no idea!!!
I ran short of time....spent tooooo much on sum ques
Bt i wrote tht energy is lost as heat n sound!!!

Was d graph 4 Cu lower or higher thn steel???

 

[m.r92]

Was d graph 4 Cu lower or higher thn steel???

lower

 

[confused123]

ITS 1000Hz for sure.....people who r telin 500Hz made mistake in cm to m conversion.....ma whole class got 1000hz ...abt 56 students...LOL...still 500hz people thnk its wrng??lmao

lol 56 fools in the same class. amazing.

 

[toirneach07]

lower

So I'll gt at lst 1 right!!

lol!!
d ans was 500??

 

[m.r92]

So I'll gt at lst 1 right!!

lol!!
d ans was 500??

but i'm not completely sure

 

[confused123]

So I'll gt at lst 1 right!!

lol!!
d ans was 500??

it has to be :| fingers crossed.

 

[toirneach07]

it has to be :| fingers crossed.

Ha!
tht makes 2 of us!!

The answer was 500.

Was that round thing/cylinder (I forgot what it was) being pulled up in q2 in equilibrium or not?

 

[maheenali]

guys nobody interested in the practical ppr tomorrow??? any guess bout it???

That uncertainty question took so long -.- I left it so I could come back to it at the end and still didnt get time to do it ! I lost marks for no reason -.- I am loosing ten marks for sureee ! But the paper was more of theory than calculations I am glad it was like that ! Btw for the output power was it the gain in potential per unit time or not ?

I hope it was.

How did u ppl gt d tension in d string nywy??

tension=W sin(angle) + frictional force
=450*9.81 sin(12) + 650
=1568 N
