Answer:The greater the density of a medium, the slower the speed of sound. This observation is analogous to the fact that the frequency of a simple harmonic motion is inversely proportional to m, the mass of the oscillating object. The speed of sound in air is low, because air is easily compressible.

Physics is horrible.
And that's the cold hard truth. :(
Answer:
Force exerted by the air on the propellers = 46000 - 9200
