Vision is blurred if the head is vibrated at 29 hz because the vibrations are resonant with the natural frequency of the eyeball held by the musculature in its socket.
if the mass of the eyeball is 7.5 g, a typical value, what is the effective spring constant of the musculature attached to the eyeball

answer; ///i do believe that the correct answer is ; ///(physical change);

the answer is a 3.8cm

explanation:

i had this question and the answer was 3.15 miles.

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 =
