    The values of the filament given are the operating values of the power and voltage when its being heated up. This value is 576 Ohm and room temperature is 16 times lesser than this value.

    Provide solution to my little problem :-)

    Honestly you don't need to revise anything for A-level physics. If anything, some of the O-level concepts don't apply in A-levels so you don't need to study them all over again. Start from fresh, your teacher should teach you everything A-level related from scratch. I don't know about Biology...

    Q21) Let the extension of a spring be 'e'. In A) the extension is e/2 because there are 2 are in parallel. In B) the extension is e/2 + e/2 = e In C) the extension is e/2 + e = 1.5e In D) the extension is e/3 + e = 1.33e C should be the answer, not D. Check the MS again. :P Q26) d sin θ =...

    Playstation Vita vs Nintendo 3ds

    This. I love Nintendo consoles (probably because I grew up with most of them) and handhelds. The games on them are pretty great in my opinion. I was never really a fan of Sony's stuff and I hardly ever watch their E3 stuff anymore. :P

    For 9, the collision is elastic so K.E is conserved. Find the total K.E of the system before, and then see which collision after has the same K.E. You could use fake values of m and u to make the calculation easier. I would do it now but I have to go now. :|

    Favorite Coldrink ;)

    Orange juice and lemonade. Fizzy drinks are good, but I don't have them much anymore because of their side-effects. :|

    Since it is a cube, one side is V^1/3 Area is V^2/3 So resistance is ρL/A = (ρ * V^1/3) / V^2/3 = ρ / V^1/3 I think..

    Q15) At terminal velocity, weight = air resistance so mg = kv And v = mg/k Now substitute v with mg/k in 1/2 mv^2 formula to get the answer. Q22) You want high sensitivity for small masses, i.e. a big change in extension for smaller masses. This means a lower value of 'k' is needed for...

    Dude I am so sorry I have gone through a number of RL problems yesterday and today that I didn't even use XPF that much. :( Are these your queries?

    0.5FE = 0.5 * 0.40 * 2 = 0.40 J k = 2/0.40 = 5 1/2 * 5 * 0.40 * 0.40 = 0.40 J I used both formulas. Both gave the same answer. But I recommend using the one which requires less working (over here 1/2 * Fe).

    35 is great. Even 32+ is a confirmed A in P1. :)

    It's A because you have to take the directions into account.
