12 10 points Astronauts brought a feather and a hammer into space because they felt like it. They are dropped on the moon from a height of 1.72 meters. The acceleration due to gravity
near the surface of the moon is 1.63m/s2. Find the time in seconds?

d.7.5cm is your answer

root word, prefixes, and suffixes

the maxium height is 34m/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 =
