Please help me physics geniuses Now you have two square cows, one mass 4kg, the other mass 2kg, lined up on a frictionless surface. You push on the first cow such that the two cows accelerate 2m/s^2
(What force does the second cow exert on the first?)

answer///terminator or twilight zone;

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 =
