    GCSE & A Level Grades in UK - Marks Percentages

    Yes. I actually came across "AAA" for the first time while applying to http://www.ox.ac.uk/admissions/undergraduate_courses/how_to_apply/index.html" (See under the heading "Late December 2008/January 2009". And please tell about "UCAS application". I have no idea about that.

    GCSE & A Level Grades in UK - Marks Percentages

    I am unfamilier with the Grading System in UK. What percentage of marks does 'A' and 'A*' corrospond to in the GCSE examinations? And how much percentage of marks does 'AAA' corrospond to in the A levels. Great big thanks to any help. :smile:

    What is the Limiting Velocity of an Electric Toy Car with Constant Power?

    Then I suppose that the answer to the first question should be v-> c at very large times even although we cannot see it directly from the equation. I guess we need to derive another relativistic expression for very large times. Right! :smile:

    What is the Limiting Velocity of an Electric Toy Car with Constant Power?

    What do you insist then; v should increase without bounds?

    What is the Limiting Velocity of an Electric Toy Car with Constant Power?

    Well I personally believe that the answer for acceleration makes sense. Initially the car might have acquired some velocity in a small time. I think the high acceleration is plausible. For velocity, it cannot increase without bounds as velocity of a material object is limited by Relativity...

    What is the Limiting Velocity of an Electric Toy Car with Constant Power?

    Another part of the question was: Find the limiting value of the acceleration at very large and very small times and comment on whether your results seem reason- able. On calaulating I got a=sqrt(p/2mt). As t -> 0, a -> Infinity. Again That doesn't makes sense.

    What is the Limiting Velocity of an Electric Toy Car with Constant Power?

    Homework Statement This problem concerns the mathematical treatment of a simple model of an electric toy car of mass m, which is initially stationary. The bat- teries in the car can be considered as an electrical power source with constant power P. Find the limiting value of the...

    Creating Wrong Answers for a Question Paper

    I donno abt the rongs but i no the rights.. I think ans 1 is \sqrt{\frac{3\pi}{G \rho}} & ans 2 =>> f= \frac{1}{2\pi}\sqrt{\frac{g (\frac{l}{2}-d)}{(\frac{l}{2}-d)^{2}+\frac{l^{2}}{12}}} for f to be maximum d=\frac{l}{2\sqrt{3}}(\sqrt{3}-1)
