In a Cartesian frame of reference, the potential energy of an object is given by where U is in joules and x in metres. In addition to the origin, the position where the object is in equilibrium is

to treat tumors in the body

im guessing the west of station b

option number c is the right answer.

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 =
