The horizontal component of a cannonball's velocity is 20 m/s. The vertical component of its velocity is 12 m/s. What is the magnitude of the overall velocity of this cannonball at this point in time?

the results is a decrease in air temperature with an increase of altitude.

explanation:

the answer to this is proletariats.

hope this : )

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 =

square root (-5^2+9^2)

square root (25+81)

square root (106)
