Charge of 20.2 mC is held fixed at the origin. (a) If a [email protected] charge with a mass of 3.20 g is released from rest at the position 10.925 m, 1.17 m2, what is its speed when it is halfway to the origin?

search it up!

explanation:

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 =
