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

[daredevil]

Thnx
I got it wrong :/

np
and aww...sorry about that :/

 

[daredevil]

Wht was the answer to the centre of mass one ?

uhhh..... i don't remember which question was that... can u elaborate a little.

 

[Mayedah]

uhhh..... i don't remember which question was that... can u elaborate a little.

Umm four shapes were given ...
First was a rectangle
Second a circle and third and forth shapes were kinda different and they said which shape will have the lowest centre of mass !

 

[gurrl]

What did you choose for the coin MCQ about that resultant force etc.? I think it was the 5th MCQ..

oh that.... it was C. the one broad at the base and narrow at the top

K thnx

the force P was increasing and the resultant force was decreasing.

 

[gurrl]

Yaaay. thanks

 

[Mayedah]

the force P was increasing and the resultant force was decreasing.

Whts the barrier for an A in mcqs ...like how many canu get wrong to A limit ?

 

[daredevil]

uhhh i'm not sure. i just know that to get an A u have to get at least 116 marks out of 145 i think. that means u have a margin of losing 29 marks in total. correct me if i'm wrong but this is just an estimate.

Q 9 part d you did it wrong, when switch will be opened, the deflection would be on the left ! (momentarily)

no it won't yr !! it will return to zero again!!

 

[asd]

well why would it btw ?? it should return to its original position at 0

As the current stops flowing, the field goes in opposite direction (back to it N-pole) as the magnet effect fades away. So the change in mag. flux was also brought in a diff way, deflecting the needle to the left. It was even in one of the past papers, and i thought of the answer in your way, but i was wrong.

i
it was 2p
pressure remain same in all the vessel...... p1*v1=p2*v2
200*p=x*100 solve it we will get the 2p has a result

i wrote 2p i thnk soo

What did you choose for the suitable Ammeter? I did 30A.
And the turbine has kinetic energy whereas the generator has electric right?
and what about conduction in metal one?

yeah both i did same..whch conduction?

 

[Doosh Bag]

Brilliant contribution from beeloooo ! Thank you very much.

 

[gurrl]

yeah both i did same..whch conduction?

if electrons move, atoms move or both. something like thaaaat

 

[Areeba Khan]

it was downwards .

i did it dwnwrds

can you tell me the values if you remember, because i guess 30 wasnt the answer.

 

[Dexterwarrior12]

well was it 2P or P/2
