    Lower bound of string was 395. Shortest length of string left would be if we take the lower bound of string(395) and upper bound of pieces of string (5.5) 10 pieces of string= 55cm. Length left = 395-55=340cm.

    D. 4x When connected as in diagram 1, both springs share the load. Suppose load is X newtons. The load acting on each spring is actually X/2 newtons, half of the load. When connected as in diagram 2, the whole load acts on each spring. So the load on each spring will be X now. The load...

    a) i) probability of all colours = 1. So probability of yellow = 1 - 0.35 - 0.4 = 0.25 ii) 1 - probability of red = 1 - 0.35 = 0.65 b) probability of green peg = number of green pegs/total pegs Total pegs= 16/0.4 = 40

    The centre of mass will be 1.5m(half of length) from the front of concrete slab. So distance from wall to centre of mass = distance of front from wall - distance of front from centre of mass = 2.5 - 1.5 - 1m
