I NEVER SAID IT WAS WRONG D:
Yours might be right, and I might be wrong!
Have a nice nap x)

hw much did u get ??

 

[Razo513]

was it 97??

 

[ZainH]

hw much did u get ??

$145 :x

 

[semsemhosam]

was it 97??

idk

 

[semsemhosam]

do u guys remeber the equations u got , i need to solve that question again

 

[Maya95]

Oh Thank God
How was it??
Right uhm the question bout solidifying what happen's to it's mass?? :|

It was easy...but I think I might have gotten quite a few things wrong. The funny thing is, SO many questions were repeated!
I think the mass doesn't change....in both cases. I'm not so sure though.

Nope sorry :s

ikr i figured it out to
Ehhhhh *-*
i think while melting the mass decreases bcz its changin state :|

Hmmm...maybe. Well, there's nothing we can do about it at this point. Just leave it to Allah.

yup

hey what about the question in p1 about the slip rings? and the one abt background radiation?

Uhm right, Slip Rings = Ac generator
Uhhhmmmm Bckground radiation = this is what i chose ---> like the rock is bring into the lab (C) <---

 

[Jisu]

Well physics wasnt that bad at all lool :$
it was a relief that there were 4 QUESTIONS that came exactly from some past papers
The rod one, wen they talk bout how'd u place that spherical thing into the rod... uhm the Buss question bout passengers not sitting on the top level... uhm other two ei dnt remembr
how was urs?

IKR!!!

 

[Jisu]

The handle one I said downwards ..
Oh the convection current one was that molecules on the surface escape.. that's what I chose.

i dont think it will move downwards....think abt it

 

[Jisu]

dudes, for the pivot question, i am sure it moved to the left, because if you remember, there was one force that was higher than the other, thus the moment of that force was further away from the pivot and the moment was higher, the 100N acting downwards would just be canceled out by the pivots upper force, but because the 100N that was acting to the left had a greater moment that the force acting towards the right, it will move to the left

thats wat i thought too

 

[ZainH]

i dont think it will move downwards....think abt it

Yeah I might've gotten that wrong.

 

[stayawayfromhere]

is i lost about 12 marks in paper 4 , will i still be able to get a star :/?

 

[ZainH]

Yep, an A* would be 116/130 .. or around that.

 

[Acarri96]

In maths paper 4, there was a question with several inequalities and you had to draw a graph and shade the unwanted areas. Then, what was the lowest possible cost???

 

[Acarri96]

It was congruent.. or equal. Since both of the triangles were exact same.
I wrote similiar.. couldn't remember the word

It was congruent, you're right
