How high would you have to lift a 1000. kg car to give it a potential energy of:
(a) 2.0 x 103 J, (b) 2.00 x 105 J,

elctricity and magnet is conversion to it

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 =
