Consider a situation in which two conducting spheres are far apart, but connected by a long thin conducting wire. The surface of the large sphere is at a potential of 1000 V above ground. The large sphere has a radius of 15 cm and the small sphere has a radius of 2 cm. a) Find the electric field at the surface of each of the spheres. b) Find the total charge on each of the spheres

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 =

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
