Imagine that the parameters r, l, c, and the amplitude of the voltage v0 are fixed, but the frequency of the voltage source is changeable. if the frequency of the source is changed from a very low one to a very high one, the current amplitude i0 will also change. the frequency at which i0 is at a maximum is called resonance. find the frequency ï0 at which the circuit reaches resonance.

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 =
