    Lol obviously i did. But i guess but im dead sure i considered efficiency.

    how did you calculate the decay constant?
  6. D

    physics paper 42 expected gt and discussion

    Took efficiency into account . dead sure it was 130g. When you used the answer we previously calculated for number of alpha particles per second we use that as Activity. and when we use that as activity efficiency was considered. Use formula A=TN and then etc.

    Oh most of his weight is converted to centripetal force to make him go in a orbit around the earth and very small forces holds him to the surface

    How was Mathematics Paper 32 2015

    Its hard to predict. People who got it right will even say it to be above 70 people who got most wrong will say around 45 etc. Expect it to be in 55-65 range

    i did the same thing you did but i subsituted V=WXo. where Omega is angular frequency and Xo is peak amplitude. Found ratios using that since the aplitude was visible on the graph. And W is same for both so gets cancelled. But your answer is close to the flipped fraction. So one of us probably...
