    What determines the rate at which an object falls to the Earth? Is it the object's shape or the mass

    I have another (somewhat related) question: if two objects of the same nature, but different masses, fall to the ground which one would achieve terminal velocity first and why?

    June 2012 A level international papers

    They'll probably be available by the end of August. They won't be available before the results, that's for sure.

    By cycle you mean wavelength right? Does that mean within one wavelength of the old wave, there has to be 4 wavelengths of the new wave? I'm kind of confused.

    Yeah, didn't read the question properly. :\ Thanks.

    Oh, I see. So since both the thermistor and resistor + voltmeter have the same resistance, they get equal V. BTW, another question if you don't mind. http://www.xtremepapers.com/papers/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_s05_qp_2.pdf Question 7 (c), I...

    How many hours do you sleep daily during the exam time?

    Like I normally would sleep. Around 11:30 (+/- 1 hour) to about 6:30. Wake up for morning prayers at around 5:00 but then sleep for an hour after that.

    Physics Resource?

    ..If all of the chemistry guesses were wrong, then how would you trust the physical practical guesses? :P

    Chemistry AS expected grades?

    Would be painful to see a result like that ruined because of one paper. :( Why a 0 in P3?

    Statistics Paper 62 -- How was it?!

    There should be. Based on my observations on the GT, a guaranteed A is like minimum 105 marks, and a borderline A is around 95-105 marks.

    Average age of A level graduate

    Normally people finish A levels when they're 18 or 19, sometimes 20. I'll be finishing it when I'm about 18.2 years old. :)

    Statistics Paper 62 -- How was it?!

    Yeah you don't need to have an A in both components to get an overall A. It just matters on how well you did overall. Someone could get like full marks in P1 and have a C in another paper, but could still end up having an A.

    www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w07_qp_2.pdf Q2 d (ii) The force calculated in (i) is 75 N and the resistance force is 23 N.. so shouldn't the power be the net force * velocity? In the marking scheme, the forces have been added instead...
