    isn't the angle 45 anways? because if you draw parallegram of forces that is what i get

    i think i got this the tension in the elastic is 4N right? (you don't divide tension by 2 just because trolley is in cneter) and since it is elastic it will move the 3omm as give by diagram and 30 mm more after YZ and 50mm=4N so 60mm=x so 60*4/50 =4.8

    because if you look the compression is from the sides so ▲l is the horizontal l and L is the vertical l so as the cube is compressed the horizontal l decreases will vertical l increases is it is flattened

    ok first find intial speed and final speed so: intial momentum = final momentum mu = 2mv so intial speed is u and final speed [v] = u/2 intial KE 0.5mu^2 final KE = 0.5 *2m * (0.5u)^2 = 0.25mu^2 final KE/ intial KE = 0.25mu^2 / 0.5mu^2 = 0.5 intial KE so C...

    Q8 answer is A because speed increases uniformly so constant acceleration Q6 + 5 when adding or subtracting 2 quantities add absolute error when mulitplying or dividing add percentage error when a quantity is to the power of something multiply power to percentage error

    pretty sure it is A because there is already a voltage V across r so when R is connected V will decrease

    Q21 i tried and failed Q35 answer is D because: you have to remember the formula v/E = R1/R1 + R2 as voltage across one resistor increases the voltage across the other decreases and R= V/I in the wire so in order to balance resistance loss you move the contact towards Y

    f=kx when all 3 springs are attached they share the load of W so each spring carries 1/3 of W so for 1 spring W/3 =kx so K of one spring is W/3x having 2 springs means 2(w/3x) which is 2w/3x now the weight is 2w so 2W = 2w/3x * x ' so x' is 3x

    use the forumla f = n*f for n is an odd number for the number of resonance in a closed air tube so 3*75 = 225 5*75 =375 more on here on how i did it...
