    I still don't know where I'm going wrong, I got 136.5367?
    Why do you use the length 0.66? And not 0.91?
    you need to use 0.66 because the wavelength isn't the total length of the string but rather 1 complete wave

    can someone help with the specimen 1 question 2.2? how did they get their area as 0.083? i got it as 0.38? was it a typo or did i do something wrong?

    Neither specimen 1's paper 1 or 2 has a question 2.2 about area. Can you screen shot?

    Question 2.2 is about volume. the mark scheme says to calculate the area which they got as 0.083333, and their final answer becoming 0.16.

    What do you think of the specimen papers? Will they present a paper like that this coming Tuesday?

    Could anyone help pls?? Much appreciated
    There won't be any questions based on experiments on paper 1? This year for our exam, only on paper 2?

    For those that think people are posting wrong questions, there is a second set of specimen papers that teachers only have access to apparently but im sure they are on the internet somewhere

    No you don't... You take the smallest possible reading it reading it can possibly be...

    Here's the unsecured Specimen 1 paper: http://physicsloreto.weebly.com/uplo..._1_qp_v1.0.pdf
    Mark scheme: http://physicsloreto.weebly.com/uplo..._1_ms_v1.0.pdf

    Would anyone help me with the moments question (q3). I can't seem to show that the wire is 50N. I did get the clockwise moments but for anticlockwise moments i have no idea why you have to do sin(30)x0.3 ???

    The vertical moments of the forces acting downwards must equal the vertical moments of the forces acting upwards - the vertical moment of the tension in the string is 0.3 x sin(30) x T, since the rope is at an angle of 30 degrees to the horizontal.

    I measured from the first line to the last line, then divided by how many gaps there were This will get you an answer within the allowed range.
    Except, when you measure the outside of the 1st one you get 5mm, and then the outside of the last one you get 136mm, so the difference is 131mm. 131/26=5.038 which is outside the range of 5.24+-0.05mm

    The vertical components of the forces acting downwards must equal the vertical components of the forces acting upwards - the vertical component of the tension in the string is 0.3 x sin(30).
    why is the vertical component not tan(30) x 0.3?

    There are 25 gaps, not 26. 131/25 = 5.24mm exactly. Remember, you are measuring the average SPACING between two adjacent maxima, so you need the total number of spacings between maxima rather than the total number of maxima.

    Thank you! I thought you counted the number of maxima, not the spacing between

    Will you say its more beneficial to go over every topic and get your wordings right using the specimen papers or just carry on with doing Questions from the book topic by topic.

    I'd say just do as much as possible, book and papers. Just make sure to look at the newest specimen papers (set 2) before the exam so you kind of know how the paper will be set out.
