Tarzan, in one tree, sees jane in another tree. he grabs the end of a vine with length 20m that makes an angle of 45° with the vertical. he steps off his tree limb, swings down, and then up to jane’s open arms. when he arrives, his vine makes an angle of 30° with the vertical. determine whether he gives her a tender embrace or knocks her off her branchby calculatingtarzan’s speed just before he reaches jane. ignore air resistance.

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 =
