. Which one of the statements are FALSE? * A current cannot produce a magnetic field.
When a compass is placed near a copper wire, with no current flowing in the wire, the compass will always point in the same direction (north).
The magnetic field near a long, straight wire carrying a direct current has a circular shape dependent upon the direction of the current flow.
Electricity and magnetism are related.

answer; the correct answer is technician a; ///100%good luck

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 =
