If a point charge of -30 experiences an electrostatic upward force of 27 mN at a certain location in the lab, what are the magnitude and direction of the electric field at that location? the potential difference two square parallel plates is 4 V if the plate separation is 6 cm and they each measure 1.5 m by 1.5 m what is the magnitude of the electric field between the plates?

compass can be used day and night, cloudy or sunny

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 =
