Which two formulas are used to calculate potential and kinetic energy? A. KE = vamp2
B. KE = mgh
C. KE = Vmg?
D. PE = mgh
E. PE = mvh
F. PE = Vmv2

P.E = mgh

K.E = 1/2mv²

Explanation:

P.E = mgh

That is m= mass in kilograms, g=acceleration due to gravity and h= height in meters.

K.E = 1/2mv²

That is 1/2 of an object's mass multiplied by the velocity squared.

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 =
