Suppose we replace the resistors R1, R2, and R3 with three identical resistors, R. What is the potential difference across each of

these identical resistors?

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

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 =
