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

It wasn't 2P it was 2P/3

 

[ISFSAT]

was electron flow written in 1st column or convection current

i want to confirm the same thing.................

 

[mastermindh]

right! May Allah give us all good grades. Aameen!

Aameen

i
i did 2p too but the sheer number of 2/3p people makes me think k i was wrong

I did 2p as well but it was 2/3 p ,,. i think like me you took 2 volumes as 2001 and 100 rspectively.,,. it should be 200 and 300 ,.,. add the other 100 volume into the first one to get v 2

 

[theViperace]

yh every1 is .... i also got 1 mcq wrongg. what did u select for the 1 in i=which we were given an electron beam and a magnetic field and we had to show wher the beam will move. what answer did u give for that??
and yh maye i exaggerated a bit but that is really the question in which EVERYBODY is confused.

It was B i guess ,.,. the wires had to repel and then u can guess the direction of magnetic lines bu using the right hand rule

conv in 1st and elec in 2nd

which mcq was that? i dont remember any such mcq

what is the "other 100 volume"? and why add?

 

[17194]

It's 2P/3
P1V1=P2V2
200xP = 300xP2
P2= 200P/300
P2= 2P/3

 

[ISFSAT]

conv in 1st and elec in 2nd

i also think it was conventional in the first column.....but many are saying it was electron flow....

 

[beeloooo]

was electron flow written in 1st column or convection current

IT WAS D!

 

[plantaholic]

i also think it was conventional in the first column.....but many are saying it was electron flow....

i remember quite vividly...

 

[pakiboy]

wat was the ans for that motorbike quest!!!!! was it B or A explain you ans!
topic circular motion...........

 

[pakiboy]

wat was the ans for that motor bike quest. was it A or B...........
Topic: Circular motion

 

[17194]

It was A. Centripetal force acting on the body acts towards the centre of the circle.

 

[irtaza ali]

The moment of force ka answser was A . using one anti clockwise = 2 clock wise
Table tennsie one was increase and decrease

bike one was A .

I still have my queries for that mcq the pressure volume one . The reason is most of the people used the formula pv=pv to attempt the question . This formula is applied when the container is some how decreasing in volume *Like a syringe * . As the containers were fixed .. one side had 200 cm3 of air .. the other had vacuum and a capacity of 100cm3 . When the valve opens .. firstly simple diffusion takes place ... causing air molecules to move from container A to B . Due to lessening of air molecules , the pressure decreases ... as the kinectic theory applies , the fewer the molecules the less chance of them striking the walls and hence less pressure . As its simple diffusion taking place and there is a movement of 100cm3 ... in container A only 100 cm3 is left , which is half the original . hence p/2 .

Those who can follow what i just wrote , please do see and some how prove that air molecules dont go from A to B but from B to A , cause thats the only way the answer could have been 2/3p

I also did p/2 although most of my friends wrote 2/3p

We

The tests below were carried out on a solution containing ions of the metal X.
test observation
add sodium chloride solution no change
add sodium sulfate solution no change
add sodium hydroxide solution a precipitate was formed, soluble
in excess of the hydroxide
What is metal X?
A calcium
B iron
C lead
D zinc

check it out

should be zinc?

 

[plantaholic]

should be zinc?

yes its zinc

 

[asad.manutd9]

yes its zinc

yayyy
