Un corredor A intenta alcanzar a un corredor B, ambos corredores inicialmente están separados una distancia de 100m, el corredor A acelera hacia B en linea recta a 1.5m/s2 (partiendo del reposo), el corredor B lleva una rapidez fija de 1.3 m/s. Calcule 1) Tiempo que tarda A en alcanzar a B.

2) Distancia recorrida por A cuando alcanza a B.

3) Distancia recorrida por B cuando es alcanzado por A.

4) Repita los apartados 1,2 y 3, pero ahora suponiendo que la velocidad inicial del corredor A es de 5m/s.

where is the circuit diagram ?

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 =
