    What did people put for the job of the iris?
    Changes the size of the pupil to control how much light is let in. I just checked my notes and that's correct

    For the one where the object fell from the sky I put the one with the curve that levelled of as I thought it was a bit like terminal veloctiy of a freefaller idk
    I put C :? because the velocity would increase as time went on, not decrease.... idk

    For the question 6 I put:
    - Protons and Neutrons are found in the nucleus
    -Electrons are found flying around the nucleus
    -Protons have a postivie charge and a relative mass of 1
    -Neutrons have no charger and a relative mass of 1
    -Electrons hava a negative charge and its relative mass is virtually zero.
    - most of the atom is empty space

    What do you think i got for this???????????????
    honestly I'd guess 6/6, or 5/6 depending on how harsh the mark scheme is on choice of words. but you included the sub atomic particles and their relative mass/charge and that's all the question asked for so

    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?
    You Didn't write about the relative masses of each so won't get full marks

    I'm probably wrong I spent ages choosing between C and B but I just thought I could remember the diagrham of a free faller soo! Idk though x

    But the north magnet was on the bottom and the south magnet was at the top, so the field would be going straight in front. Using the left hand rule i got up, but i might be wrong
    I got up aswell
