    I am repeating my As level.

    I am repeating as I said, so I dont care about practicals. And I prepared for paper 1 and 2 by myself and I'll get an A in physics even if I get E in practicals ;)

    Post all of ur doubts here Mishi :)

    Use formula of young's modulus and make F as subject of formula, get for P and Q and then divide it :)

    Saad ro mat :P 14) FIRST OF ALL,BOTH NEWTON METERS ARE SHOWING TENSION IN THE STRINGS AND WE HAVE TO FIND THE VERTICAL COMPONENTS OF BOTH THE FORCES. VERTICAL COMPONENT OF 4 NEWTONS FORCE IS: COS(37) = X/4 , SO X = 4COS(37) = 3.19N VERTICAL COMPONENT OF 3 NEWTONS FORCE IS: COS(53) = X/3 , SO X...

    Well weren't they easy :P (jk) 38) Here we are asked to find total EMF in the circuit. We'll use the formula : EMF*(R1/R1+R2+R3) = V Now we wont consider 4R coz its parallel attached to other 3 resistors, hence --> EMF*(2/6) =2 so EMF = 6V 35) Will have to type alot, wait.

    5) Vo = (5*2*1) = 10 (principle volume value) Vu = (0.01/5) + (0.01/2) + (0.01/1) * 10 = 0.17 So volume = 10 +/- 0.17 And mass = 25 +/- 0.1 Uncertainty in density = (0.17/10) + (0.1/25) * 2.5 = 0.05 12) Clockwise = 20 * 0.4 = 8 Nm Anti-clockwise = 10 * 0.6 + 100 * 0.1 = 16 Nm (don't forget...

    w12_12 29) As you can see from the figure, there will be total difference b/w nodes = 3λ / 2 = L Now we know the velocity, we can calculate λ so f = v / λ λ = 0.2 m f = 1650 Hz 34) Let's go choice by choice shall we...: B: It's said both are made from same material. So resistivity is same...
