Why don't we observe the debroglie wavelength of everyday macroscopic objects, such as a moving car? the macroscopic objects are moving too slowly for the wavelength to be observed macroscopic objects do not possess wave-like properties the macroscopic objects are moving too quickly for the wavelength to be observed the wavelength is too small relative to the moving object to be observed the wavelength is too large relative to the moving object to be observed?

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

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 =
