How much would a man on Mars weigh if he had a mass of 75 kilograms and the acceleration due to gravity on the surface of Mars is 3.7 m/s 2?

. west

the part of the wave he is travelling on is the crest

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 =
