    Anyone have any good notes to learn about solar system, phases of the moon and eclipses, reflection and refraction ? These topics are not covered in my syllabus (CIE board). Thanks

    I'm not sure, how to do it? Can you show me your working and the other answers as well so I can cross check instead of constantly bothering you you
    You can pm me if you want

    The questions with marks at the sides are from PAT past papers. Question 17, 20 and 24 were from UKMT senior challenge 2012 and 2011. Solutions are in the website below. Question E ( from test 11) and 2 (I am finding hard time figuring out which paper was this question from. I am sure this was from MAT) were from past MAT papers and solutions are presented in the website below.

    This is the discussion thread for the upcoming Oxford PAT 2016. Any candidate applying for Physics, Engineering and Material Science (alone or along with other subjects) should sit for PAT exam.

    Does anyone else struggle with the time? Specially on the physics part? The multiple choices itself take me a good while gosh

    Glad I'm not the only one. I guess you've just gotta make the decision to abandon a question sometimes, so you can earn more marks elsewhere on the paper

    As a Scottish student is there anything in the Pat that isn't covered in Higher or Advanced Higher maths or physics that I need to know?

    Top of that I'm being piled with tests at school so barely any time to practice

    As of last year there are no longer multiple choice questions on the PAT/the long answer section has also changed, so while the physics of the questions is valuable practice the paper format before then is pretty useless in terms of practicing timing.

    Assuming you are asking for clarification of the question, not the solution, the question asks you to compare brightness of each bulb in each circuit (the cells and bulbs in each of the case are similar) to the bulb in the first circuit.

    Ohms law and P=V^2/R comes handy in the solution.

    I mean, I knew what the question asked for
    could you explain each case to me, ie why is something brighter/normal/dimmer?

    Here we go!!!
    Note that R is constant for all the bulbs.
    a) The source is same so the total voltage is same but there are two bulbs in series so voltage drops equally among the two bulbs. As P= (V^2)/R, we see that the bulb is dimmer.
    b) Here the total voltage has doubled and each bulb gets half the total voltage so the bulb is as bright as original i.e. normal.

    d)This gets really tricky. The first thing to note is all the current flows from positive of the cell to the right to the negative of the cell to the left. Using Kirchhoff's first law in the junction joining two cells and d, we see that no current flows through the d so the bulb at d is off.
    c)Removing the unnecessary d from the diagram, the diagram looks similar to b and hence normal.

    e) Note the fact that the voltage across resistors in parallel is equal and equal to total voltage. So ignoring (f) for a while this matches the circuit diagram of a, hence dimmer.
    f) Using the same argument we can ignore lower two bulbs (as voltage is same in parallel) which leads to the original diagram i.e normal.

    g) and h) Using Kirchhoff's rule again we see that no current flows through the vertical wire at the middle. Now upper two bulbs are in parallel to the lower bulb. We also note that total voltage is doubled here. Using similar arguments to that of e) and f) we find that g is brighter and h is normal.

    Hope this helps. Please don't hesitate to ask if you don't understand any of the points above.

    Also, the book "Classical Mechanics" by Morin is awesome.
    Thanks to rohan.nuck for the recommendation.

    I' applying to engineering at oxford (obviously), as well as Bath, Durham Southampton and Warwick. Are most people on this thread applying for physics or Engineering?

    So hi. On the syllabus for the PAT it talks about electromagnets and magnetism, so does that mean it's worth learning about electric fields, magnetic fields/flux, faraday's Law and all that (because it looks pretty difficult aha)

    Hey!
    Personally I think it would be since you want to get all the marks you can and giving marks away cause you don't know the content as oppose to can't do the question doesn't seem worth it. On the bright side it's not all as difficult as it looks!
    Good luck!
