*** was that(physics paper 3)

[Saadiya Ahmed]

For the distance time graph
the first part i got was Accelerating
then constant speed
and then deceleration
and the highest speed was 350/45
and average speed 600/whatever the total time was
anybody else with similar answers?

Yeah i guess...and the max speed was 9.33 ryt?!

 

[Weirdal95]

no highest speed= 350/45.....average speed was 400/60.
7.777, 6.666

The highest speed was wen the speed was constant ryt?@

 

[Weirdal95]

yes when it was constantly accelerating

 

[Saadiya Ahmed]

yes when it was constantly accelerating

xDxDxD

 

[IGCSE O/L student]

yes when it was constantly accelerating

dere ws no constant acceleration

 

[shalala]

dere ws no constant acceleration

yes when it was constantly accelerating

Wasn't speed decreasing, speed constant and speed increasing?

 

[IGCSE O/L student]

Wasn't speed decreasing, speed constant and speed increasing?

it ws acceleration, constant speed, n den deceleration n stop

 

[shalala]

it ws acceleration, constant speed, n den deceleration n stop

I don't think sooo!
Anyway, what did you write for the wate rise, fall and rise+fall?

 

[Hamzeh S]

no it was 300/45 ? the graph was max at 300 not 350 :S ?

it rises coz da molecules in da liquid xpands
it falls coz da molecules @ da surface leave da liquid
i wrote use a copper flask 2 transfer heat more efficiently. wbu?

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

 

[shalala]

I don't remeber properly... But it was something like it will rise b/c temp of wwter ismore than flask...

 

[Hamzeh S]

yaa !! it decreased in the beginning because test tube expandded
then rise because liquids expanded as it gain Ke ...etc
then why is it higher because liquids expands higher than solids

wat abt da resistance question which ws for 4 marks?

oh, great. now my ans is wrng.

 

[Hamzeh S]

you add the resistance that awas in parralel
and then use V = IR
so v = 6
and I is equal to the current in you find in B + 0.8
and R is equal to the current in parralel X the Resistor we need to find
i got 1.8 Ohms

i think dats wat i got.

 

[Hamzeh S]

the Pistons i wrote that it need mor force because more area and pressure is constant so the force increase
the reason it moved less i wrote it had much more area and that it required more force
the air bubbles in the oil will cause the oil to become compressable hence reducing the efficency or function of the piston

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