    Now WHAT was that space exploration question about? I think that's proof enough these exams are becoming a bit abstract.

    Edit: I mean, I could think up of an answer for it, but the question itself had be reading it again and again to see if my eyes had deceived me.
    I share your feelings

    I thought the "why should we explore space" question was a ****ing joke lmao.
    I should have written 'so stephen hawking still has a job' somewhere on the back page for a laugh.

    Is that due to vacuums?

    It was so tempting to put, 'well, in space, nobody can hear you scream...'

    Yeah, space is a vacuum so there is nothing there and sound is a vibration of particles so if there are no particles to vibrate then sound cannot travel through it

    I feel cheap and used that I bothered to revise for that test.

    Ok, starting to feel a little more confident about this paper, lol! I put for the last question 'decrease radius of CIRCLE' forgetting I was talking about an attraction as well. I'm also worried they won't accept film because I didn't put photographic before it. Cling film?

    what was the crane question?
    It asked you to use the force = distance*weight thing.
    what did it ask after that?

    Haha, the paper was a good laugh though. Some parts I made a royal mess on and just let my brain go on autopilot (concrete weights question) Also in every physics exam I always have quite a bit of a crossing out and that one sorta did have quite a lot..

    Magnification: 0.35
    Distance of crack within metal: 90
    Coils of wire on secondary within transformer: 10500
    Device inside Camera: LDR
    ..........
    Isn't the Distance of crack within metal 45 becuase it question said from the start of the block to the crack NOT from the start of the block to the crack and back again.

    I agree with the LDR but it could have been aperture

    I put the camera sensor as a photodiode, but I think that was fine, but I hated the magnification question, I had discovered that when they said it was 1.4cm it was really 1.2, so I got the magnification as 0.42, so I hope for an error carry through.

    There may be multiple answers for the camera thing. The aperture opens and is SENSITIVE to light, but doesn't capture it.

    The distance was 90mm because its only measuring time where the opportunity arises to half. I might have had a brain-melting moment and just wrote 9 though

    I put that the wave is longitudinal for a feature of Ultrasound (I know its the same for sound too, but that should be okay...I think )

    Yes, I nearly only wrote 9 for the ultrasound. Didn't like the space opinion question, I wish I had just said I was against it (which I'm not) because it is much easier to explain; wasteful, expensive pointless.

    Oh well, I only needed to get 65 UMS for an A*, so I can afford to muck stuff up big time!

    What reasons did people put for features of Ultrasound. I put:
    Over 20kHz
    Partially reflects on hitting a change in density.

    Any other suggestions.
