Two 4.0-cm-diameter aluminum electrodes are spaced 0.50 mm apart. the electrodes are connected to a 100 v battery. part a what is the capacitance?

Capacitance, is the ability of a system to store the electric charge. the capacitance of two 4.0-cm-diameter aluminum electrodes are spaced 0.50 mm apart is .

The capacitance of a parallel-plate capacitor in vacuum,

Where,

A - Area of plate  =

d - distance between plate = 4 cm

- electric permittivity -  

Put the values in the formula,

Therefore the capacitance of two 4.0-cm-diameter aluminum electrodes are spaced 0.50 mm apart is .

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 =
