    MJ 06 Q22 The Work Done is the area under the graph. We are treating the curved part as a straight line as said by the Question, So area under graph Uptil X = 0.5 * 10e-3 * 500 = 2.5 J Area under graph from X - Y = 1.05 J Therefore total work Done = 3.55J Answer is B

    M/J 06 Q9 This is a typical graph of Simple Harmonic Motion. The Answer is D This is because consider an object at the equilibrium position. It has displace zero and MAXIMUM velocity. Let's say it goes upwards then once it reaches the highest point it's velocity will be 0 and it's acceleration...

    Physics MCQS

    This graph is of elastic hysteresis. The area represented by Z is the energy that is recoverable. Therefore the Area X and Y is the work done after loading and unloading. Work Done when loading: X+Y+Z Recovered when unloading: Z Therefore Work Done: X + Y Hope you understand

    lazy jigga man

    If you work a bit harder you can actually get an A and 2Bs :) depending on well you have done the AS papers. Try to get a 65 / 100 for chem 4 and phys 4 and 20 / 30 for phys 5. That should get you a B at least :) Feel free to ask any questions if you have any doubts in topics.

    Physics P1 Questions

    Ok P = h$g where P = Pressure h = height $ = density and g = gravitational We know total Pressure is 17.5 * 10^6 Pa We first consider Pressure by Oil P = x * 830 * 9.81 P = 8142.3x Next we consider Pressure by water Here we have to consider height as (2000-x) since we are given total length...

    PLEASE HELP ME REVISING PAPER 1 PHYSICS CIE

    Only AS Level, but a bit of A2 Knowledge won't hurt. But since P1 is so close I suggest sticking to and learning the facts on AS Level and if you are confident with it only learn A2.

    PREDICTIONS A2

    A2 vectors is not it's just confusing. Sometimes you just don't know what to do and whether to find the common perpendicular and so on. For me I always draw a large diagram with everything marked and it helps a bit
