*** was that(physics paper 3)

[IGCSE O/L student]

You seem rude?
Oh sorry 4got u r a girl!

sayin "awww" is rude????

sayin "awww" is rude????

Yes it is ,for replying to people who are crying!

The Exam Was Like A Shit . ! I was Crying When I get out of the exam hall :/ ... It was realy bad !!

 

[phantom]

I think the paper was quite good, it was way better than I expected.

v1?

 

[phantom]

v1?

Yes, and it wasn't only me, many of my friends found it good too, some even said it was easier than Oct/Nov 2011, what was the hardest questions you encountered??

 

[Patum]

oh, LOL! dats wat i did. but i wsnt sure of my ans. dats y i asked. thnx alottt! <3

did you do variant 1? because I did variant one and the answer was that.. they might have changed some numbers around depending on the variants

sry, i didnt knw dat.
i wont do it again!

yes, i did variant 1
thnx again!!!!

Excuse me

For the 22500 one i put 225000 and Im pretty sure thats the right answer :X

if you mean that question which asked about the energy (VIT) it is equal 45 000 000 !! and i am sure

 

[Omar Hosny]

lmfao, hi
lmfao dude, the maximum speed was, 280/30 = 9.33 recurring ( the constant bit) and the average speed was 400/60 = 6.6 recurring. I'm sure i'm right.

sorry bro maximum speed means the accelerating part plus constant speed!! 7.77

 

[Hamzeh S]

sorry bro maximum speed means the accelerating part plus constant speed!! 7.77

no its 9.33

You just took values from the graph and divided them (distance/time) thats wrong, cause when you do that you get the average speed for the whole journey before that point, you should've found the distance travelled from B to C (i.e the straight line) and divide it by the time taken to travel that distance, if memory serves me correctly, I believe it was 280/30 which gives you 9.33 (recurring) m/s.

350/45 cuz speed is the gradient of the distance/time graph get gradient of line AC it is 7.77

How can you get the gradient of line AB in the first place, its a curve, so you cant find its speed, you should find the gradient of the straight line BC

woow! dats wat i wrote 4 da buuble question. n i totally made dat up! trust me!

It is important that a hydraulic system contains no air bubbles. You may have heard about the need to "bleed the air out of the brake lines" of you car. If there is an air bubble in the system, then the force applied to the first piston gets used compressing the air in the bubble rather than moving the second piston, which has a big effect on the efficiency of the system.

yeah i got you but come on by this u got speed of BC what about AB ?

 

[phantom]

BC was steeper than AB (By Eye), so it had more gradiant and thus higher speed, so AB had nothing to do with it.

 

[Jisu]

i dnt knw wth ws wrng wid me but dis is wat i did.
350-70/30
wat an ass i am!

thats wat i did too
n u get 9.33
but stupid ol me wrote 11
cuz i mistyped in ma calculater....

 

[Busy Buddy]

It waz really bad coz everyone has different answers!!!

 

[Manobilly]

I guess we must discuss it after 24 hours ,we must take care of the rules guys.
