Dos masas se encuentran unidas por una cuerda que pasa por una polea. La masa sobre la plataforma horizontal es de 3.38 kg y la masa colgando tiene 6.95 kg. El momento de inercia de la polea es (1/3)MR2, con M =13 kg y radio R =0.41 m. Calcule la aceleración de las masas

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 =
