*** was that(physics paper 3)

[IGCSE O/L student]

I screwed up the LDR and the beta particle questions
Now I feel that I can't even think of an A* in physics

i screwed up da part where dey ask wat happens 2 da air molecules in da path of da beta particle.

The paper was harder than usual.
What did you guys get for the pd , resistance and current in the circuit question?

I got 2.4V,,,,,,,,,,,1.2A,,,,,,,,,,and 1.8ohms

 

[Roselian]

i got 18.13, or sumthin where da second number after decimal is less dan 5.
approzimatel, my ans ws 18.1. n i got it usin da average. dats da way 2 get da ans

Cool! Some people got it using frequency (1.8 was the most frequent) that's why I'm asking.

alot of ppl did dat. but usually wen u do an xperiment, 2 get da best, u shud take da average. dats y we draw a graph of our results

there's one question after u figure out the charge, Q=IT then after that they ask you for energy, you use IVT , what was the answer again, i got something like 4x10^11 or something,4,6 can't really remember

4.5 x 10^7 or 45000000 joules.

english, maths, chem, bio, physics, accounts, business, n ict
yahoo messenger? it's kinda impossible coz my dad's here. he'll kill me. y dnt u inbox me in xtreme?

 

[EpicLol]

hmm they askd abt design so copper is wrong, u had to talk abt using thinner capillary tube. nd level falls cuz of evaporation i wrote tht too, but i think its wrong. my brother is in AS level and i told him the qs , he said tht the flask xpands (its glass) nd a little volume increase causes the level to fall.

No u put fatter tube not thinner.....I put fatter

could I discuss on xtreme papers as well?
I want to plzplzplz

u shud use thinner. dis will inc da rate of xpansion

Oh sry it is make it smaller.....I put bigger was that a 1 mark question?

sure.
EpicLol RSDEV let's create a conversation.

 

[EpicLol]

yup....I lost like 15 marks.....or a little more maybe I hope I still get A*.....I got 35/40 in paper 1

 

[aneeqa]

i screwed up da part where dey ask wat happens 2 da air molecules in da path of da beta particle.

u screwed up small qs b happy. i m jst losing like 11 marx for sure rest idk prolly more

 

[EpicLol]

sure.
EpicLol RSDEV let's create a conversation.

how can we create conversation?

yes, it ws. dnt wry.
