Physics paper 3 IGCSE Oct.Nov 2013 discussion

[qasimnisar2121]

So guys as many have already done it and many will be doing it nearly, this thread is to discuss about it that how was the paper and what question was the hardest and stuff.... so whatcha waiting for?? do vote on this poll!

guys i have a physics exam in 3 hours and i need help, the electrons is said to have the lowest mass, when a question comes up saying does electrons have mass or not, what do i say?

 

[qasimnisar2121]

Efff... it was effing lenghty!! >.< SarahCh8 how was urs??

 

[Lanocaster]

What did you guys get for the time (2nd question), I got 5s
And what did you get for the vectors question, I got 49500N

Yeah I got the same!!!!!

 

[SarahCh8]

Yeah, it was lengthy! It was quiet good except few parts.
What did you write for the last question second part answer, about the working of thermistor when it's temperature is set below, bla bla?

 

[qasimnisar2121]

I wrote the thermistor controls the amount of heat in a circuit

 

[SarahCh8]

And what answer you got for the volume for the bottle?

 

[saroooor]

what did u get ???

 

[SarahCh8]

I don't remember buh I took the 4. something atm pressure x volume divided by the 9.something pressure. :S
wbu?

 

[qasimnisar2121]

And what answer you got for the volume for the bottle?

V. Of bottle was 130 cm or something close to it!!

 

[SarahCh8]

Yusss, what frequency you got & what ratio?

 

[Raj12345]

h

Yeah I got the same!!!!!

Hey I got 41000N for the resultant. is it correct? i drew the correct parallelogram and chose 1cm=5000N fot the scale. pls tell me if am correct or wrong.

i guess u r rite 4 the 2nd question.. i also got something like 5.04 s bt as for the vector diagram.. whereas i remmbr i got 14000N resultant.. i guess u r talking abt ariant 32.

 

[Alla' Abu-Sultaneh]

When are the answers for the exam coming out?

 

[qasimnisar2121]

Yusss, what frequency you got & what ratio?

I firgot... i think i missed the ratio one but freq. Not sure i wrote something like below one or near!! Really dont remember

 

[SarahCh8]

acha.
uMm, what did you write for the reason of collapsing of bottle? about the train thingy passing through slope & about why the other side of copper sheet doesn't cool?

 

[qasimnisar2121]

uMm, what did you write for the reason of collapsing of bottle? about the train thingy passing through slope & about why the other side of copper sheet doesn't cool?

collasing of bottle was that on top the mountain their was less air so when the bottle was opened, the air in it left but addition air didnt enter the bottle other side i wrote, they cant cool down to different temp. as they were both in the same room with same room temperature!! and about train thingy it needs to lift its whole mass on a slope, to gain G.potential energy and so there is a need to increase the engine power to keep the speed constantly 24m/s!! hope this is correct!!

 

[qasimnisar2121]

Alla' Abu-Sultaneh why your paper was "Super Ultra Bad" ???
