Two parallel paths m apart run east-west through the woods. brooke jogs east on one path at 66 km/h, while jamail walks west on the otherpath at 77 km/h. if they pass each other at time t=0t=0 , how far apart are they 44 s later, and how fast is the distance between them changing at that moment?

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 =
