physics paper 1,2 ........can we discuus da papper nw?

awesome....

yar conventional and electron flow was like this:

-----------------> conventional
<---------------- electron

yeh kaisey ghalat kardia?

And heat was conducted using electrons+atoms vibrating

By the way, i only messed up the pressure MCQ. No other mistake !

 

[xxvvyy]

from the positive terminal of the battery is conventional current, from the negative terminal is electron flow am i right guys?

 

[beeloooo]

1. How is heat conducted in a metal
2. electron flow and conventional current.

hey electron flow and conventional current was D , than how was it wrong yr ??

 

[xxvvyy]

yeah it was D

 

[beeloooo]

yu

from the positive terminal of the battery is conventional current, from the negative terminal is electron flow am i right guys?

yup

yar. bas, i dont know
maybe i wanted to lower the threshold xD

 

[xxvvyy]

haha anyway dont forget the BET

yar menay ghalat kia ha, aap ka sahi hai D

 

[beeloooo]

yar menay ghalat kia ha, aap ka sahi hai D

plus for the metal conductor which option was right ??

 

[xxvvyy]

so wt else was hard guyz in mcq?

 

[bikermicefrmars]

yar. bas, i dont know
maybe i wanted to lower the threshold xD

hahhaha....im sure you'll do great. By the way, yar pressure wala waqai meh 2p/3 tha? I wrote 2p...lol ... its surely wrong !

 

[Fallen316]

plus for the metal conductor which option was right ??

atoms + electrons.
i did only electrons.

yup , 2p/3

 

[xxvvyy]

atoms and electrons correct , it was there in the book

 

[waztaz123]

About the MCQ about current flowing in opposite direction. What was the answer. I think it was B. The Magnetic field lines were concentrated in the center and the flow of those were somewhat upwards...if anyone remebers, because it is difficult for me to explain without drawing.

 

[bikermicefrmars]

What is meant by wave motion?
In the last question sec B....only alpha and gamma existed, right?

 

[xxvvyy]

u hve to use left hand rule...yeah it ws upward

 

[bikermicefrmars]

And what was Distance D in wave question?

 

[ashiqbal]

guys can u please tell me what did u mark for the length of wave in one second? and which direction did u show the X moving?
