    i used the rule but i didn’t know which way the current was flowing as it did not say
    I think you just have to know that the current goes from positive from negative on the battery (long side to short side i think)

    Can you tel me how you worked out the maximum speed was 22.5 m/s?
    I just did 170 over 10 to get 17 which probably isn't right.
    hey max,
    it said maxiumum speed so I assumed I'd need to take a measurement purely from the straight line, so I put my ruler on the line and marked when it began to curve off. the line was straight from 80-170m on the y axis, and 6-10 seconds on the x axis, so that got me 90 metres, and 4 seconds, and when I did 90/4 it got me 22.5m/s

    No - it's 20Hz to 20kHz
    No the human hearing is between 20 hz and 20khz. Ultrasound is above 20000hz

    Did it ask for human hearing or ultrasound?
    Ultrasound so 20,000Hz

    Also for P3, when working out the angle r did we all remember to use inverse sine?

    It moved up as current flows from positive to negative from the cell/battery

    Higher P3 and you had to label the retina and suspensory ligaments
    I did higher and there was no labelling. They were already labelled.

    I think the people talking about the labelling eye question may have done PH3HP paper, while people who DID NOT get the question did FAS3HP paper (who sat core last year).
    I don't remember any labelling questions and I did FAS3HP.

    I think it's acceleration

    Did you do last years paper? It was way easier than this years?? And it was 44 for an A star.
    I think 43 for unit 2 and 45 for unit 3 (lower because of the silly mistakes it looks like many people have made)

    Which question was that?! I don't remember it! I remember one that asked what causes the acceleration or something like that

    Yes, cause as you can clearly see what happened in water. Also the space to do refraction was very small- should've given you a hint it wasn't that. I put partially reflected, whilst some people put it went along the boundary.
