Two people fell down, one onto hard cement and one onto softer grass. Both people had a mass of 100 kg and were moving at 4 m/s as they fell. The person who hit the hard cement came to a complete stop very quickly, in .01 seconds. The person who fell onto the softer grass also came to a complete stop, but they did so more slowly, 0.5 seconds. What force did each of them experience when they came to a stop? Force on person who fell on cement Newtons Force on person who fell onto grass Newtons

i believe the answer is electric potential.

explanation:

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 =

c) a core temperature of only ten thousand kelvin
