Fire the projectile launcher straight upwards (angle = 90o) at 18 m/s. Using kinematics, determine the time (in seconds) it should take the projectile to reach maximum height.

i need to show me the graph so i can give u an answer

e/c, where e is its total energy

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 =
