What is the electric potential v due to the nucleus of hydrogen at a distance of 5.292×10−11 m ?

27.21 V

Explanation:

The electric potential due to a point charge is expressed as:

Where:

is the electric constant

is the electric charge of the hydrogen nucleus, which is positive

is the distance

Rewritting the equation with the known values:

Finally:

answer: 31, 5556. 952 seconds

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 =
