In the circuit above, ϵ1 = 9.10 V, R1 = 7.60 Ω, R2 = 2.40 Ω, and R3 = 4.60 Ω. The ammeter reads a current of 0.800 A. What is the power dissipated by resistor R1?

the maxium height is 34m/s

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 =
