First of all, I am aware that its impossible for a planet with less gravity than the Earth, to naturally maintain an atmosphere with the same terrestrial gases, in an equal or greater proportion. Therefore, this proportion of gases is maintained artificially.
Second, although I have notions of what the ballistic coefficient implies, I have no idea how to calculate it or in what proportion its affected by the atmospheric density and gases of an atmosphere.
Following with this line of thought, we have the force of gravity of the planet X that is 8.04 m / s².
Let us assume then that the atmospheric pressure of this planet, whose atmosphere is being altered artificially, is approximately 2 atm.
Now with all the elements previously presented, I would like to know two things:
- 1) Would this atmosphere sustain intelligent life in a realistic way? It is necessary to know if a human civilization could develop there.
- 2) Would the effect of this atmosphere be enough to significantly affect the ballistic coefficient, to the point where its preferable to a civilization that has discovered firearms, have to continue using crossbows for more effective shots at a distance?
Note:Take into account side effects that may present apparently inert gases at high levels of partial pressure, such as nitrogen narcosis.
