AQA Physics PHYA5 - Thursday 18th June 2015 [Exam Discussion Thread]

Scroll to see replies

Ours was PHYA5/1R

Sounds as though AQA dished out the same papers in different locations; but with different exam codes....

EDIT: For section A at least; for section B this is (of course) expected...
(edited 8 years ago)
Unit 5 with turning points

JUNE-2014 A* 51, A 45
JUNE-2013 A* 54, A 49
JUNE-2012 A* 53, A 48
JUNE-2011 A* 61, A 55
JUNE-2010 A* 57, A 51

This year was harder than 2010, slightly easier than last few years :

Likely to be A* 56 and A 50 - cant see why it would be majorly different to this

I got...

Thermal and Nuclear
Range of = 0.05m
Range of = 0.3m
Density =
Number of nuclei =
Energy used = 47000J

Temperature = 319K

Astrophysics
Maximum distance = I got totally wrong...
Diameter = 3.0m
In the 6 mark essay my period was 4 days, and my velocity was 114 kms-1
Magnitude = -0.008
Temperature = 16100K
White dwarf radius =
Black hole radius =
Age of the universe =


Do you think I might get marks for 0.05m and 1.0m for their ranges?

And what's that about the shield becoming radioactive?
Original post by CD223
Agreed. Last year was easy compared.


I agree, I can't see the grade boundaries going up that much to be honest.

Probably. Not confident on my beta range.

I hope they dont because I made so many stupid errors.
Original post by CD223
sorry! forgot to change a few -

1.45 for the density of nucleus and 2.27 for the number of nuclei!


The number of nuclei definitely required reading off the graph, what about the density question?

The grade boundary was 52 for an a* last I think it will be at least 55 this year

is this astro or turning points. I can see it going higher for turning points

Astro
What are the requirements for an A* in physics? I'm not sure whether or not to get my hopes up :biggrin:
For anyone else who did the applied module; how do you think it compared difficulty wise to previous years?

Personally I found it harder than some of the previous years; but mainly due to mostly being word based questions (there didn't seem to be much maths this year).

I am better at maths than explaining stuff; but it could've been much worse I guess.

Same here, especially on astro with the first question and that white dwarf one!

90% UMS average across three modules; so 270 ums at A2 (but you 'only' need 80% average across all modules).
The 6 markers on section A and turning points were absolute gifts (if you'll pardon the pun)

Yeah something like that probably, it was 58 for full UMS last year. There's no way it will go above 60 for A*

cheers, I wont get my hopes up then
What element did we determine the nuclear density for? My answer was a tad small compared to some others I've seen.

Here's what I did.

EDIT: There's an error in the notes as they forget to cube r0.
