I got the pipe question... if you look at it, the full length is 18, so half is 9.. then there is a right angled triangle, with opposite and adjacent sides, so you use that to find the hypotense;
x^2=5^2+9^2
x(2)=106
x=10.3 cm!
At least I got it rights+ smiles

I have the paper 1 with me so I'll look up q's

This is how i worked out the variation:

F=s/d^2

pretended f=1, s=1 and d=1

1=1/1^2

then halved s to make 0.5 and doubled d to make 2

F=0.5/2^2
F=0.5/4
F=0.125

And 0.125 is 1/8 of 1, so it divides by 8

Yeah quite a few people in my school couldn't do that question either; I think that this year was much more difficult then the previous years.

I put

pi x diameter (which gives you the circumference) x 70 (the length) = 1000

then rearranged to find diameter

Well the general was a piece of cake tbh, and I was starting to feel optimistic for this exam, then I opened the credit paper and nearly died! If Im honest I found credit paper 2 alot harder than paper 1 but I kinda gather that overall Ive failed ... quite badly. Especially as all the awnsers here are very different to the ones I wrote.

Does anyone have copies of the papers they could send me? Much apprechiated.
