The distance from home plate to the pitchers mound is 18.5 m. If a pitcher is capable of throwing the ball at 38.5 m/s, how much time does it take for the ball to reach home plate? Round to the hundredths place

increase masses, decrease separation

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 =
