    What's the formula of uncertainty? Is it uncertainty in x/value if x= 1/2(uncertainty in y/value of y + uncertainty in z/value of z)? Or do we remove the half?

    7i? Isn't that the part where we formed the equations? :/ we've been doing that since forever! Part II was weird tho...I got 3 instead if 2 as the acceleration

    If the distance is given in cm...do we convert it into meters? Are the equations only applicable when the quantities are in their SI units?

    Yeah. And p1X is the weight of A

    You have a triangle p1XB...you can calculate P1X cause its the tentionib that string and XB is the tention in that respective string...so appy the cos rule...sorry I don't have the question in front of me so I might be confusing the labels. Anyway you can calculate the third angle by subtracting...

    The three forces are initially inequilibrium ie the resultant is zero. If u remove one of the forces the resultant will then be of the same magnitude as the removed force but in the exact opposite direction

    Post your AS-Level Mathematics (P1 and M1) doubts here.

    The tention in p1X and p1A will be the same, and the tention s in p2X and p2C will be the same, but they'll brcdifferentvfton each other. Find P1X and then calculate P1(X)B -angle X in that triangle. Next find P2(X)B by subtracting that angle from 90. Now you will have two known forces abd 3...
