    Umm i think we are doing different papers, chicano, because there were no gas molecules questions in my paper. I did AQA Physics Module 1, quantum and Mod 3, electricity. How about you, maricon?

    :confused: i did the emf = V +Ir thing
    I did emf = I (R+r) .... so same thing, rearranged.

    Can anyone confirm my diagram answers for the Mod 3 electricity.
    The 2nd question: i just drew resistors in series, with a battery, and then a simple parellel circuit. so easy i think it may have been a trick question.

    And the question were you must measure voltage and current. I drew a battery, a variable resistor, the thermistor, and the ammeter all in series. Then the voltmeter in parellal to the thermistor. Is that right? Then i connected the voltmeter and the ammeter in parellal to a datalogger. Is that right? Also i didn't know what a thermistor looks like, so i just drew a box and wrote thermistor in it. HAHAHAH you think thats ok?

    I know this post is like a week late but just so people know,

    The last question on the mechanics paper about the Trolly, I initially thought was wrote incorrectly - I got wrong in the exam but when I got home it "clicked" and I could do it extremely easily.

    The triangle of forces is above the picture of the slope and trolly. With the weight of the trolly (7200N) acting directly down and the angle being 30 degrees (Pi/6). The opposite being the length we are trying to find.

    Using Sin = Opposite/Hypotenuse

    Sin 30 = Opposite/7200N

    Opposite = Sin 30 x 7200N

    Opposite = 3600N.

    Which is what they wanted.

    I was so enraged that I could not do that simple calculation in the damn exam paper, hope it hasn't seriously effected my grade.
