What is the change in electric potential energy of two particles on with a charge of 1.2 nC and the other with 2.3 nC that start with a distance of 0.05 m between them and then are separated by 1.1m

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

answera compound;

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 =
