    Physics Paper 12 How was it

    No it said distance between maximum and minimum, so it's lambda over four. A is the awnser. Also how did you guys get 0.12??? I did area of trapezium and I got 0.8

    Physics Paper 12 How was it

    What I don't understand is that where is the clockwise force on the block... I awnser d as well, but I didn't rly understand.

    Yeah that was c I think D was like horizontal component=Q or something Can anyone tell me what the momentum question was?

    Physics Paper 12 How was it

    Wasn't the component vectors on c?? I don't know about th strain energy part.. I did 1/2(25+20)x7mm and I got approx 8..

    The path of E is parallel to velocity so theres no reason for it to be parabolic. since E is pointing to the right, the positive area is behind the electron. So, the electron is being pulled back, hence decelerating.

    Do they accept parallex/zero errors?

    Am I in trouble?

    Do CIE penalize people for untidy answers? Like for number one of physics 22 I didn't see the powers so I had to cross out my working again an again. And I had to write on the blank page beside. I also had to cross out my answers. Will they minus my marks? :(

    Physics paper 34

    Guys is it ok that i convert mm to m? So for k i got large numbers Also is my limitations acceptable? Zero error on micrometer Parallex error when reading angle Not enough readings Can be high friction on pin, or the hole is uneven, so the pendulum stops before its intended angle

    When finding k i converted mm to m is it acceptable?? So i got awnser in the thousands

    Ah k. intercept for me is 3.2mA 2 readings not enuf parallex error when reading the degrees zero error of micrometer high friction on the pin by the pendulum makes it so that the angle of oscillation is less/or the hole is uneven

    eh? we have the same wires? O.o my ds were o.75 and 0.88

    How was it? gradient=2.98 a=2.98V b=931.0ohm % uncertainty of k is 13.3% relatively low % suggests relation is supported, but more readings must be taken
