two mass Ma=2kg and Mb=5kg on incline are connected together by string as shown below the coefficient of kinetic friction between each mass and it's incline is 0.3 if Ma move up and Mb move down determine. (1) the tension in the connecting string. (2)their acceleration​

answer; /// the above statement is (true);

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 =
