    For the kinetic and gravitational energy questions concerning the rocket i put 3.6 J
    And for the height i got 7.2 m
    Got this too! Did anyone else put 3.6J for both of them (one question after another)

    Had trouble figuring out the direction of force in the motor effect because i couldn't remember which side of the cell symbol was positive and which was negative! I put the arrow upwards but i think that was wrong
    I've done exactly the same!

    I did originally but then crossed out the 3.6J for the second one and left it blank. So annoyed 😩

    I think it's because it experienced 3 half lives from 80-10 (it halved 3 times)?
    I put 3 half lives 80 to 40 1 life, 40 to 20 2 half life, then 20 to 10 3 half life.

    Just want to make it clear that half-life question is 12

    It require A-level maths knowledge to solve it which is logarithm rather than just divide, of course you can trial/test to get the answer.

    Did anyone else put 12 hours per half life? Also what did people write for the six marker? I wrote the following but I'm really nervous about it:
    - The nucleus has protons which are positively charged and neutrons which have no overall charge.
    - The nucleus is orbited by electrons which have a negative charge.
    - Protons are heavy
    - Neutrons and electrons aren't heavy
    - Atoms are very small

    Complete work solution:

    80/2^n = 10
    2^n = 80/10 = 8
    n = log 8/log 2 = 3

    half life = 36/3 = 12
