How did you find it?
Will the grade boundaries go up or down?

It wasn't nice and just not a good paper compared to b2/c2 so I suppose the GB will be low (47/60 A*, 40/60 A, 34/60 B)

Considering last years P2 paper was MUCH easier and the grade boundaries for a B was 33, i would imagine that the grade boundaries would be around 29 or 30 for a B?

sorry yeah.... I mean 30 :smile:

I hope you all found it alright :smile:

I think it was a pretty hard paper, so I'm assuming the boundaries will be low :smile:

It was horrible! Just looked at last years paper and i would easily have got an A... but i will be incredibly lucky to get a B in this one

I found the questions confusing so I just hope the grade boundaries will be lower...what answers do you remember putting for some of the questions?

I Remember that i put:
Dust particles get a positive charge and attract to the metal plates.

They gain an overall positive charge.

17N for rocket resistant force

Mass of ball 7.1kg

LDR in bright light = resistance falls
LDR in cloudy sky = resistance increases

Box A for the GPE graph

Box C for the first multiple choice question

When ball is falling its GPE turns into kinetic energy

When the ball hits the sand its kinetic energy is turned into elastic energy

Last 6 mark question: the battery doesnt run out as quick because current is conserved at a junction and not as much voltage is needed to push round the current at night

Thats all i can remember

EDIT: I couldve sworn that we never learnt about the electrostatic air filter system????

I am pretty sure you got some wrong because the question said it has a negative charge then it said how did this happen. It happened because the electrons got transfered to the dust particles. Then it said why did the dust particles lay on the metal plates. That was because opposite charges attract. Lastly it said why did no charge get built up. If you looked at the graph it had a bonding line linked to earth therefore any electrons get transfered to earth

Oh ok i think I got 2 out of 3 right... was the first multiple choice question C?

you don't need to have learnt it to answer the questions, it was just applying your knowledge of static electricity

Yup just realised... however most of my year answered those wuestions wrong as well

What did you guys get for some of the equations?

What a horrible exam! The final 6 marker confused me no end, as what kind of a traffic sign is dimmer at night? Surely it should be brighter! I could still apply the fact that more light on LDR = less resistance = more current = brighter sign, but the entire logic seemed completely backward! Not a nice exam whatsoever...Found the meteor collision question nasty, hoping that negative velocity means a change in direction too for that other 6 marker. Reckon it'll be 47/60 for an A*, but I think it was so horrible it should be 45/60! Last year was a doddle in comparison.

I got 48 for one of them? And 0.07Kg and 0.03N - but those ones were a little confusing so odds are I got them wrong. God bloody hate P2 XD At least P3 is easy in comparison!

yeah have to agree, the 6 markers weren't so good cos there was hardly anything to write about for LDR!

I thought the first 6 marker was awful, i put deceleration for stage 3 and 4 when it was decreasing but apparently the rocket wasn't falling down but it was just losing velocity? it just confused me so much, especially that question on the argon-40 with the graph i pretty much guessed the last bit to that question
