*** was that(physics paper 3)

[areebaization]

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??

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

Dont be so upset, the exam was tough for many, the threshold will be low, you need to forget about this exam and move on, and prepare for next one, this isn't the end of the world, plus if you did good in paper 1, and do good in paper 6, then all you need is just 65 to 75% in paper 3 to get the A*, Good Luck.

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.

Aww...I feel like an idiot.....I just took the whole dist before the BC and then calculated with time...this gave average for whole journey behind this line...
Do u know how many marks that was worth?

3 marks, 1 for the correct speed equation, 1 for the right values, and one for the answer with units

yeah ok...I think I got about 14-18 marks gone....

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?

i got the same but max. speed, 9.33 m/s

 

[IGCSE O/L student]

Excuse me

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

yes 45 000 000 is da ans. dats wat i got. but i dnt remember my ans 4 da other question

 

[aneeqa]

The graph question, 7.77highest speed, average speed was 6.66m/s and the first three were constant speed, constant acceleration, constant speed.

yh all wrong xcept average speed is ryt

i dont remb max speed but it was the gradient of line BC. nd average speed no, cuz it was 400/60=6.67

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?

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.

dey asked chnge in apparatus, not da design.
it's wrng?? :'(

 

[Lost_Life]

oh, LOL!

hey um you did paper 6??

 

[aneeqa]

for the Max. speed , i got 9.33m/s , is that right ??

yh if u found gradient of line BC nd got tht answer

 

[Lost_Life]

Guys, did you sit for paper6 already!!?

 

[aneeqa]

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

me too i got tht beta particle qs wrong . i wrote umward force instead of downward. nd wrote parabolic path instead of circular path

 

[aneeqa]

dey asked chnge in apparatus, not da design.
it's wrng?? :'(

yh probably cuz wat they mean in those qs is to talk abt design. copper is probably wrong

 

[Lost_Life]

UM.... did you guys sit for paper 6!!!!!!!?

dats wrng 2. damn it.

For the first question, I wrote 18.19 cuz I found it by the average, not by the frequency. Do you think I'll lose the mark?

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
