    question 4: between the 2 pulses there is a difference of 3 boxes. since the time interval between the pulses is 0.006 seconds, we say that 3boxs=0.006 seconds so 1 box=2*10^-3seconds hence answer is C question 10: not sure if i'm correct but here it goes..... v^2=u^2+2as since the vehicle...

    using kirchoff 1st law conservation of charge we can say the current coming out of the cell is 1.2+0.4=1.6A no we find the potential difference of the 80 ohm resistor. v=ir so v=96 since 1.2*80=96v so terminal potential is also 96v because parallel components have the same potential difference...

    v^2=u^2+2as u=8 a=-9.8 s=1.9 therefore v=5.17..... 1/2mv^2=Ek so 4.014J THE ANSWER IS A

    :cool: i'm gonna guess oscillations of paper clips with graphs where the period is propotional to the sq root of length and the 2nd part is gonna end up being something to do with density hence the scales are used :cautious:

    Physics: Post your doubts here!

    Thats all i know........ This morning i found out that there were no electrical apparatus for the practical and now a a user by the name of amina1300 told me that her school predicted that paper clip oscillations and scale weight balancing is coming.... the oscillations part is gonna be doable...

    apparently if you're doing paper 33 then you're going to do oscillations and...... scale balances what ever that means o_O

    Physics PAPER 33 HOW DID IT GO?

    usually if the percentage difference in k values is less than the % uncertainty in values then the the readings have a relationship. So lets say you have 2 values of D and 2 values of X and the ration D/X gives K so..... K1=1.5 and k2=2.29 the percentage difference is 53% however the...

    WHO HAS PHYSICS PAPER 31 ON 17TH MAY?

    it really shouldn't matter but i cannot prove why as i get a 2-10% difference when between both methods. But to answer you question personally i would do k1-k2/k2*100. so essentially whatever you minus you divide it. And if that is greater than 10% then there is no proof that your results...

    CIE PHYSICS 9702 PAPER 33 MAY 17TH 2017

    idk about you guys but there are some rumors about whats coming up on the exam, apparently only mechanics and oscillations experiments not electricity. My questions is what are the mechanics experiments, cause i've skipped most of the practical sessions :c
