hey no discussion b4 24 hours

 

[no.mercy]

hey dude..dont be mod-police..you are just a 20 post member

 

[dramaeybaaz]

my answer wz 2.5 sec too..

but but i did 40cm/0.16 cm per sec = 250 sec....

 

[Maleeha]

i dun remember but i did 40/16... sorry forgot the question though

 

[Maleeha]

yea i thnk i got the speed 16 cm/s in other words 0.16m/s

 

[no.mercy]

the frequency was 2 HZ...and the last was like this as the length of wave 8 so 40 cm is equal to 5 waves..now in one second 2 waves are produced...so 1+1+0.5 is equal to 2.5 sec

 

[leosco1995]

I wrote 2.5s too, but you never know. We could be wrong and you could be right.

But I agree, it's best to not to discuss the contents of the paper because we could get banned.

 

[no.mercy]

okay then lets stop discussing..whoever wants to discuss get on PM

 

[leosco1995]

Or you could discuss it on chat, the mods don't really bother checking people out over there.

I don't want to discuss the paper, though. There's no point.

 

[Arslanjaved]

why to not discuss the paper ? :S

 

[dramaeybaaz]

yea...no point...
now for mathzZZzZz.... 8)

 

[leosco1995]

why to not discuss the paper ? :S

For one, we're apparently not allowed to discuss the contents of the paper unless 24 hours have passed because it's a rule here. Secondly, there isn't any point because the paper is already over and if you find out some of your answers are wrong, you're just going to feel a bit depressed or annoyed and you might not be able to concentrate properly for the next papers. It's just my opinion.

Hello everyone!
I hope you did this paper well.
But as you know, this is violation of rules. So, I guess, I should lock this topic!

 

[Nibz]

Now you can discuss it

The answer was A for MCQ 40 as the number of atoms dont chnge after the half life. Its just that they convert from unstable to stable.The qst asked for the no of atoms after 12 years not the no of unstable atoms thus answer wud be 40 million.

@nomercy:- Tum tu bura hi man gae!!!

 

[no.mercy]

dude you may be right coz this thing is really ambiguous in the sense that such kind of question is not seen in past papers (if it has occurred then give me the link)..well i still have 39 and they are way more than enough
