AQA GCSE Physics triple higher paper 2 15th June 2018 unofficial mark schemeWatch
I got a huge number for that (5 million something) which sounds more correct that 15 completes orbits, considering that 7.7 km/s is a very high speed.
What I did was: read off the value for the distance of 1 orbit, divide it by the speed which was 7.7 km/S. and I got 5000 something for that.
I then multiplied that answer by 60x60x24 as it asked you for the number of orbits per 24h.
Anyone did that too...?
I needed to recall my paper 1 knowledge lol
