Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEi screwed up the last question, damnit! hopefully they'll pity me and i'll get 1 mark or something :/ what are the predictions for grade boundaries?(Original post by Frankster)
Yeah it's right.. i really hope i don't cock this one up as well! -

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEI reckon it may be 35 for 90 UMS, 38 for 100 UMS. It wasn't as bad as the P3 so should be higher than that...(Original post by xoxlovelifexox)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEI'm sure that the answer to the first part of the question was 7.6kJ (efficiency question), but I don't think that's what you use for the next question, because that asked you how long the boiler would last, where you have to presume it is using all its power that is supplied to it (8kW), whether it is used efficiently or not.

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEohh you mean the next part, i see.. you're right it's 200 / 8 - 25 hours.(Original post by bezabe)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEP3 was horrible. it really made me doubt whether to take A-Level physics.(Original post by Frankster)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEHAHA! LOL SAME HERE!! I was like I'm ******* for A levels if I don't get A* in Physics esp. as I want to do Eng. at uni.(Original post by xoxlovelifexox)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEi'm actually so nervous about physics! let's hope we get what we want! fingers crossed!(Original post by Frankster)
HAHA! LOL SAME HERE!! I was like I'm ******* for A levels if I don't get A* in Physics esp. as I want to do Eng. at uni. -

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEjoin the club. if only i thought to divide 200 by 8 and i wouldn't be so annoyed at myself.(Original post by Aidanb90)
I want to kill that boiler question I put 200. I looked at it over and over
, the rest was simple though

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSESnow, I'm sure there was a question like this on a past paper ski put that, and funnily enough the next question was about skiing(Original post by Frankster)
Also what did people get for the UV reflection question? Sand or snow? and why? -

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSE36 for full UMS? what would you say would be the grade boundaries?(Original post by ClarkyC...)
It won't be 38marks for 100 ums I don't think, if anything it'll be 36. It wasn't that easy, there were some tricky questions
Anybody putting marks scheme up? I can't actually remember the questions haha -

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSESnow. The higher the value in the table, the more was reflected by the ground into the eyes of the robot. Besides, white, dull surfaces reflect more light.(Original post by Frankster)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEYeah but wasn't the question asking: "Looking at this graph/results which is better" I put sand because there was less UV intensity found in the dummy so most would have been reflected... ?(Original post by ClarkyC...)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEThey gave you the half life = 30 years.(Original post by abss96)
how did u get 90?
For 600 to 75: 600 - 300 - 150 - 75 <-- that's 3 half lives.
30 x 3 = 90 years. -

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEI've History exam so can't do that until I come back! By that time it'll probably be up though. Oh and thanks for the neg! Really appreciate it.(Original post by ClarkyC...)

Re: PHY1H (OLD SPEC) Unit 1 AQA GCSEIt was snow, there were higher levels of UV detected because the snow reflects more back into the dummy's eyes. . . I think.(Original post by Frankster)
