How much is required to accelerate a 5kg mass at 20 m/s2

use F = ma

F : force m : mass a : acceleration

so

f = 5kg * 20 m/s2 = 100 N

c) power lifting, will be your answer.

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 =
