Three forces acting on an object are given by F1 = (−2.00 i + 2.00 j) N, F2 = (5.00 i − 3.00 j) N, and F3 = (−45.0 i) N. The object experiences an acceleration of magnitude 3.75 m/s2. i. What is the direction of the acceleration?

ii. What is the mass of the object?

iii. If the object is initially at rest, what is its speed after 10.0 s?

iv. What are the velocity components of the object after 10.0 s?

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 =
