800-kg roller coaster moving down on a frictionless inclined plane at an inclined angle 25 degree. Calculate

1.Weight ( force due to gravity)
2.Horizontal and vertical component of the weight
3.Normal force
4. Net force along the plane down
5.Acceleration

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 =

there are no atoms
