A football player runs directly down the field for 45m before turning to the right at an angle of 25 degrees from his original direction and running additional 20m before getting tackled. What is the magnitude and direction of the runner's total displacement?

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 =
