Explain why the rock may topple to the righe 11. The figure shows a non-uniform log or mas 100ky balanced on a pivot
by a 2 kg mass placed as shown
2 mn
Pivot
Determine the distance of the centre of gravity of the log from the pivot​

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 =
