    Same here!! I think the highest point on the graph was 170m in 10 seconds and speed = distance/time
    so 170/10 = 17
    Me too

    So was tthe half life 3... Or 12!?!
    I put 12. When 80 is halfed 3 times you get ten. So half life is 36/3 = 12.

    Guys, let's put this behind us and focus on the upcoming exams
    Is there anything we can do to change what we've done?
    No.
    Is there anything we can do to change our final grade?
    Yes.

    Revise hard
    Exactly, although it is hard to not chat about the answers with other people, it's just the tradition :P

    I got 12 by doing 36/3

    Posted from TSR Mobile
    For half life you do 80/2=40 for one year
    40/2=20 for two years
    20/2=10 for three years
    Then 36/3 years = 12 years

    for the 6 mark question I put:
    - The nucleus contains positively charged protons and neutral neutrons
    - The nucleus makes up most of the mass of the atom
    - The nucleus is overall positively charged
    - There are electrons on the shells which are negatively charged
    - Most of the atom is empty space
    How many marks do u think this would get?

    But it wanted the fastest speed, so I presume you had to take points from where the line was straight and then work it out from there...
    Same, what answer did you get?

    I put ciliary muscle which one was it?

    It'll be both right I think. In 2013, you'd have gotten a mark for labelling one part of the eye a lens or an iris in the first question so I think it'll be the same case here.

    What did pole get for the focal length change? I got confused with that aha.

    Oh thank God. I got 3.6 initially but I thought that was too low so I converted it into grams. Hopefully we at least get 1 mark :/ I still got 7.2 for the height question
    Same. That's why I did it again. Lol. Hope so. What did you get for max speed?
