If the extension of the spring with the unknown blue mass is 12 cm, determine the value of the load (in kg). Use the spring constant determined in the previous answer. Use the gravitational constant as 10 m/s_squared. Give only the number as an
answer, do not include the unit when entering the number in the block below

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 =
