# Physics P1 Edexcel GCSE 20th May 2015 watch

1. (Original post by ScienceGeek1878)
I got 1.97, You should have wrote what you got, but if they do reduce marks, it will only be 1
Damnnn im soo kicking myself i shouldve left the answer as it was....

I got 1.96 but on the dotted line i wrote 2 hrs will i still get full marks?
No, I don't think you'd loose marks but usually its best to round to 3 significant figures . And for the light question I got a really long answer but I'm pretty sure it started with 1336 but I'm not sure, my calculator didn't give it in standard form so I didn't write it as standard form
3. Everyone, what did you put for the question which said why the temperature ffor the wing remained constant? I'm pretty sure I got that wrong!

I wrote heat lost is the same.rate as the heat is gained therefore it reaches a constant temperature??

I think that would get you two marks , i wrote some BS about heat not being lost in a vacuum, I over-thought it and didn't read the question thoroughly
6. I wrote that the same amount of heat absorbed is being radiated out to keep the temperature constant...not even remotely sure if that's correct lol XD
7. Hey, this paper wasn't easy but it wasn't difficult to be honest but I'm just annoyed with one question.
The graph.
It had an equation of (S-P) multiplied by 8= Km or something like that and it asked if the graph was reasonable or something along those lines.

I'm pretty sure that is the correct answer!! Asians are good at physics woohoo (I'm chinese )

Ok, I think I approached the question quite smartly, I'm good at maths haha. I just plotted the line of Y=8X on the graph so I can compare the lines, and it showed that the further right you go the closer the two lines are (better estimate), but the two lines NEVER touch so it is never a perfect estimate hope that helps!!

Haha, i always make silly mistakes and feel bad about it afterwards

same i wrote that it radiated the same amount of heat it absorbed

India...Kerela to be even more precise

It's a relief to know that other people wrote the same too wwoo! I'm kind of feeling better about the exam now haha

I said that the equation was reasonable because it gave a similar result to the actual result shown on the graph and I provided evidence for example I said that 10 seconds it had an arrival of 80km in the equation and the graph showed it was actually 78km which was very similar. They equation should have said (S-P)x8 -2 that would have given the exact same results as the graph

Thats a great observation!!
