On an aircraft carrier, a jet can be catapulted from 0 to 260 km/h in 1.90 s If the average force exerted by the catapult is 9.40×105 N , what is the mass of the jet?

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

scientific laws are the result of testing theories and proving them to be facts.

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 =
