    Mathematics: Post your doubts here!

    Need help please! November 2013, Paper 31. Question 8. (b) Just need help in finding the least value for |z-w|. Also need to know if there's a method to do these questions. Also Q4. I have tried doing this on Wolfram Alpha too and that gives a different answer to the marking scheme. Can...

    Mathematics: Post your doubts here!

    November 2013 Paper 31 Q4. Can anyone please help in this? Even Wolfram Alpha gives different answer to the marking scheme. Q8. (b) How do I find the least value of |z-w|?

    How was Physics/12 paper?

    Check GT of June 2012 and Nov 2012. Both below and around 25.

    How was Physics/12 paper?

    Are you mad? Have you checked June 2012 and Nov 2012 GTs? Both 25 and below. For variant 12.

    How was Physics/12 paper?

    Exam was very lengthy. All the questions were doable but time was too short. I don't expect GT more than 26. It was almost like November 2012 and it's GT was 25.

    Chemistry and Physics AS paper 12 MCQS

    Paper 12. Q5: x= 1.28-0.83 = 0.44 Error in x = 0.02 + 0.01 = 0.03 Uncertainty= 0.03/0.44 * 100 = 6.88 Answer D. Q14: Length of Ramp= 1.5/sin30 = 3m Work Done against Friction = 150*3 = 450 J Work done against Gravity = 200*1.5 = 300 total= 450+300 = 750 J

    But this will not be the current across ammeter. Current across ammeter will be the voltage multiplied by resistance here as it is paralled and voltage is same across all. I = V/R = 12/2 = 6. B gives 4.5 ohms. C gives 4. A gives 2.4

    Assumed the voltage provided is 12V. You can assume any voltage but 12V proves to be easy so I use this. Now calculated total resistance of each arrangement, and calculated the total current in the circuit. I will do for the D part. R= (1/1 + 1/2 + 1/2)^ -1 = 0.5 I= V/R = 12/0.5 = 24
