A step-down transformer converts 120 V to 5 V in a phone charger. If the primary coil has 600 turns, how many turns are in the secondary coil?

A transformer for a phone charger converts a 120-V input to a 24-V output. Show that the primary coil has five times as many turns as the secondary coil. 120-V/24-V

Explanation:

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

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 =
