    PHYSICS 9709/THEORY PAPER SIGNIFICANT FIGURE PROBLEM

    There was a question where the answer was 4.533333333.......*10^-3 the ans in m.s was to 2s.f. that is 4.5*10^-3.:)

    Ah one more thing thought blocker there was a question where the answer was 4.533333333.......*10^-3 the ans in m.s was to 2s.f. that is 4.5*10^-3.:)

    Some questions the data is to 2.s.f and if we can't state the answer to a greater number than justified then it should be to right?:)
  10. B

    Physics: Post your doubts here!

    Then if the data is to 2.s.f then we must leave the ans to 2.s.f.

    Will the examiners cut marks for our answers s.f. not being the same as m.s s.f.? And it was 50 50 for me some questions in papers are to 2 others are to 3 sometimes within the same question different parts!!!

    Thought blocker can you help me out in the s.f problem?
  13. B

    Physics: Post your doubts here!

    How can both be same 1 ans is to 2 s.f. other is to 3.s.f. and the marking scheme gives to 2 s.f. And why won't they cut marks for s.f., the grading threshold is so low because they do cut for s.f..

    PHYSICS 9709/THEORY PAPER SIGNIFICANT FIGURE PROBLEM

    Can anyone please state the number of significant figures wee should leave a answer to in the physics theory paper?:) Would the CIE examiners cut marks for wrong number of significant figures in the final answers?:)

    There is a question where the answer is 4.5333333333.....*10^-3, how many s.f. should we leave that to?
  16. B

    Physics: Post your doubts here!

    Shall I give you some questions which are clearly given to 2.s.f?:(
  17. B

    Physics: Post your doubts here!

    Would they not cut marks for s.f
  18. B

    Physics: Post your doubts here!

    But in some mark schemes some answers are to 2 s.f
