It was 0.17, because you had to give It too 2 significant figures, and the number was 1.16666666 so 0.17


i did it to 3sf, so 0.167 - they should allow that too right?

What was that very last question all about? The one with the binary star thing?! I didn't understand it at all!

it was showing you three different red shifts. one was fow a fixed position star and the two binary stars were orbiting it, you had to use the redshift to explain how this was evidence.

basically the red shift of the fixed position star was in-between the red shift of the two binary stars(stars that orbit each other) so that proved the two binary stars were either side of the fixed position star. furthermore one of the binary stars showed red shift while the other showed blueshift so one was moving away from us while the other was moving closer to us, this meant the stars were orbiting each other and around the sun. -i thought it was a very hard question but i had revised this, it was a bit stupid to write all this for 3marks, i had the time so i thought i might aswell
The question on sperms was slightly confusing, I think I got full marks on the last question about stars...personally I think the exam was alright. Not really hard, I was expecting worse actually.

I made a load of silly errors on this paper. Was easy if you didn't catch yourself out.

I put the mobile phones have no direct contact with sperm?


I wrote other factors could affect sperm count, i.e Age. Some of my mates however, wrote rather disturbing answers. :/
