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

I cant remember the question but it was something like this. Show that energy of (electron or molecules cant remeber ) is 4*10^-13 J

I got 4*10^-14J

How did everyone else do it.

find relativistic mass (1 mark)
use E=mc^2 as it wanted total energy so you get 3.somethingx10^-14 (2nd mark)

Explain what is meant by the specific heat capacity of lead. (2)
Amount of energy needed to raise temperature of 1 kg of lead by 1 kelvin

I dont know r u asking this question or telling us

I did e=mc^2 but got 10^-14 it was supposed to be 10^-13

lmaoo don't watch g. moretime iv got an A* tbh.

what u planning on doing next year?

You have to say 'without it changing state'

I rate that still.

Mechanical engineering at Imperial. If you are at imperial next year you have to link me g.
my firm is mathematics at imperial still, Ill holla ya when the results come through.
My offer includes STEP exams, so it depends on those if i get in or not

I was a good exam. Excpet last two question on turning points i messed got some weird number.

Did u do turning points

"with no change of state" is a pretty important part of the definition I think, when I've seen it before you need that for the marks.
Ah, well I'm glad I included it then! Makes up for the stupid mistakes I made on other bits

STEP is deadly, you'll get it though bro. Hope to see you there g. Be reloading that stormzy over summer to get you through the trauma still.
17. They better mark mine right for beta travelling 5m.... It says they can online and also that's what I learnt from our ALevel class handbook.
18. Will be interesting to see if the boundaries increase for this given people seem to agree it was similar if not harder than last year's?

I hate medical physics! I'm doing Mech Eng at uni and it doesn't help in the slightest. Our teacher's claimed it was the easiest module though, so I just went with it. :P
aw no! It would've been so much better to do applied then not fair you didn't get to choose! lol it so isn't, purely cos of the detail you need to learn
