The creepy crawlies that survived the main presentation to the synthetic at that point reared and passed on that imperviousness to their posterity, and through proceeded with bug spray applications that would execute the weaker bugs, the ones that survived were the ones who could oppose the chemicals best.
1) F = m.a
Here, F= 99N, a = 12.5 m/s^2
m = F/a
m = 99/12.5
m = 7.92 Kg
2) weight = mg
Here, m = 55 Kg, g = 9.8 m/s^2
W = 55*9.8 = 539 Newtons.
