Atmospheric drag is proportional to su2 where s is surface area and v is velocity. kinetic energy is proportioanl to mu2 where m is mass. terminal velocity is that velocity where the drag force balances the force due to gravity (mg). (a) show that the terminal velocity, v scales like m1/6 for similarly shaped objects. (b) show that the kinetic energy per unit area scales as m2/3. (c) use this to comment on what happens to small vs large animals if they fall down a great height. (d) show that the height at which terminal velocity is reached scales like m1/3 (hint recall from hs physics that potential energy is mgh.)

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

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 =
