: Write down a mathematical expression that relates the gravitational potential energy of the hanging mass (G. P.E.), the kinetic energy of the hanging mass (KEtrans), and the kinetic energy of the rotating platform (KErot). (System: Platform Mass Hanger Earth) Using words and an energy bar chart, describe how these quantities will behave as the hanging mass descends and the platform rotates.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

v=ir = 3x15 =45 v

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 =
