The force of magnitude f acts along the edge of the triangular plate. determine the moment of f about point o. find the general result and then evaluate your answer if f = 100 n, b = 480 mm, and h = 220 mm. the moment is positive if counterclockwise, negative if clockwise.

i think its c if i'm wrong

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
