Q 1 / In a sapphire laser with a wavelength of 694.3 nm, the sapphire crystal is 0.1 m long and the reflectivity of the two-time mirrors is 97% and 90%. If the amount of loss is 10% for each complete cycle. Calculate the wind (gain) coefficient of the threshold? And what is the inverse qualification to obtain such a profit coefficient if you know that n= 1.82 change in frequency v = 3×10^12 HZ and the second residence time is equal to 200×10^-6sec​

if they have a finite resultant

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 =
