HELPPP PLEASE A car starts from rest and accelerated uniformly at a rate
of 4.00 m/s2, E and covered a displacement of 200.0 m
a. Calculate the time it takes to cover the displacement
b. Final velocity
c. Average velocity

like poles repel so keep pushing north to north and repels funny to see this

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 =
