    Anyone else get 1600m/s for the ultrasound one?
    I did! Also, as that was in P3, can I ask whether the lens question was asking you to describe how the image changed as the object got closer to the lens or as it got further away? I can't remember and it is freaking me out!

    That exam was hard!

    I think I messed up all the calculations.

    Did anyone remember getting these?

    600 Ohms for resistance
    0.015 Amps
    400 Joules
    100 Newtons
    84 Kg
    22 m/s^2
    For the last question I got 0.1m/s2did anyone else?

    Did anyone tick 'gamma' as the least ionising or 'beta'?

    Yeah, you had to use POTS (position, orientation, type and size), don't stress

    I thought the earth wire connected to the fuse, which I what the question asked, unless I spaced out?
    I put earth wire as it works in conjunction with the fuse

    I did that but i just found out I described it as if the object moved towards the lens and not away like the question said. I am so annoyed at myself......... It's almost the holidays though!

    Alpha radiation was least ionising.

    Does anyone know the answer to the one about suggesting what the disc theory meant about other stars or something like that? I had no idea

    That is a joke? It is the most ionising if you actually think this.

    Ionisation ability
    Ionising radiation is radiation that has enough energy to cause other atoms to lose electrons and form ions. The different forms of radiation have different levels of ionisation abilities:
    Alpha particles – very ionising
    Beta particles – moderately ionising
    Gamma rays – weakly ionising
