# Edexcel A2 Physics Unit 5 'Physics from Creation to Collapse' watch

1. (Original post by dancing.barefoot)
btw did everyone get 5600 as the temperature of the sun?
I think I did.
2. I need to know how much I need for an A <_>

Unit 1 - 106/120 (A)
Unit 2 - 102/120 (A)
Unit 3 - 48/60 (A)
Unit 4 - 92/120 (B) - And I'm not sure my retake went any better

Now assuming that for Unit 6 I will get around 35/60, and that 80% (480 UMS) is an A - If that's how it works, then I need 97 for this exam.

Anyone got any clue what 97 would be?
3. lets get this straight was it T^-1 or.....

its T
I got it wrong.

T^1
6. can anyone explain why its T
7. Worst case scenario 61/80, best case 69/80. I'm content with that

Anyone have the chemistry unit 5 paper?

The max A can go to is 60 for this paper, so I think 61 would be a good guess, but it all depends and your unit 4 and 6 marks could make a big difference to it.

can anyone explain why its T
cz the frequency is inversely proportional to the max wavelength, and the max wavelength is inversely proportional to the temperature, so the frequency and the temperature are directly proportional!
10. (Original post by Zak979)
can anyone explain why its T
λT = constant

since λ=v/f

TV/f = constant

TV = constant x f

Therefore, T is directly proportional to f.

For me worst case, 60/80 best can go upto 75, but personaly I think impossible.
But there is hope.
12. ok i see, damn
13. is question B the answer to question 1
14. (Original post by Zak979)
