A small body A starts sliding from the height hh down an inclined groove passing into a half-circle of radius RR. What is the minimal height h from which the particle is able to reach the top of the circle?

im sorry i dont know

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 =

amplitude

hope this
