For question 2)ii) I thought about taking the surface area of the earth (4pi(r^2)) and dividing it by 14 to find the area needed to be covered per orbit. I then worked out the actual area covered per orbit (3000*2(pi)r) which was less than the area needed to be covered. So the answer would be "No". Also note that the difference would be larger as each time the satellite orbits, it covers the same area twice at the poles.

Any idea why the method was wrong?

Yes - but it's not on general release. Your teacher can download it from the secure OCR Interchange area.

We arent allowed to share it or post it - so please dont ask.

My mark scheme is very very close to the official one. ie all the answers are right!
