Oxford PAT 2016

i can send it to you if you really want it.... but honestly its more of a A2 revision pack than anything else so not so worth it

there are solution on tsr... but obviously they were done by some very clever people since they jump loads of steps and it ends up not making much sense... but i have yet to find an incorrect solution
if the solution really doesnt make sense post it on here and we can all have a go at it

Thank you so much. Please do it.

Do you have preparation tips for interview too? Thanks :d

Some of the answers given in the page might interest you.

Great Post:

Just to clarify knowledge should be learnt is:

Physics Unit 4 - Ideal gas laws/circular motion/newtons laws etc.

FP2 - Inequalities

C1- Arithmetic Series

C2- Logarithms

C3 + C4 - Learnt Fully


Do I need to know much from FP3, C4 vectors etc

Thanks

errrmm just go in with the mindset that you won't get in... made me super chilled and calm but honestly... imagine sitting in front of three professors...being attacked (logically) for every answer you give... and knowing that your future depends on the next 30 mins... lots of stress

Now imagine being asked how many airplanes are in the sky right now and mumbling your thought process for about 5 mins straight and getting lost in your thoughts and to finally have to ask the tutor - would you mind reminding me what i have been saying for the last 5 minutes because i somehow got lost in my own mind xD

oh you got that one!! i just got a load of maths which college was this at?

That was my second interview. I also got asked about a ball rolling down a staircase there ( maximum number of consecutive bounces ). On my first interview i was basically asked to analyse a situation about cars on a road, sketch a weird graph and asked to say what x=cost y=sint z=t would look like. That was Mansfield college. Had a third interview at wadham where i got asked to derive centripital acceleration and equation of motion and something about the angle between earth sun moon when we see half moon
Edit: I would have prefered loads of maths xD

Those questions are challenging for sure. How can one prepare for the interview?

There's nothing from FP3 you need to know and I've never seen C4 vectors come up. Don't think it's even on the spec

This is an interesting question to think on.

tysm

No problem at all

This is an interesting question to think on.

same reason as why dust appears to float in the air i guess
I guess the horizon motion cancels out from dem air particles and you could just count the weight as another strike from air particle from above and hence top and bottom cancels out too so it floaatts
as for the last part... im guessing something to do with two moving towards each other hence gain mass?

My best guess goes as follows:
So basically i would think of this as the net density of the cloud being less than that of the atmosphere.
The Mass of air has a lower density to that of the surrounding air and so it rises. As is rises further up, the atm pressure decreases and so mass of air begins to expand even more while the cloud also cools down ( as higher up temperatures are lower) so there is a net decrease in the energy/internal energy of the mass of air. This causes the water vapour to condense into a less energetic form ie water droplets. But sine the mass of air is still filled with air its density should not be that much greater or less than the air itself. Hence its stays in the sky at somepoint. and we have a cloud. It does not fall because its density is less than that of air. Even though it could be greater than that of air at somepoint, it would still have an upward velocity at that time and so it would only decelerate blablabla ( and probably oscillate about a mean position )
as for the last part, i'm guessing that it has to do with the droplets colliding with each other and gaining weight. but as this happens kinetic energy is not conserved, so the temperature of the cloud decreases again causing more condesation ---> eventually density becomes too high/droplets too big and it falls ?
EDIT : where does this question come from? an easy but interesting question : Imagine putting some helium in a balloon, and then letting it rise. Describe the motion of the balloon ( assume the balloon is hard as hell and does not burst xD )
