Lastly, Newton attempts to extend the results to the case where there is atmospheric resistance, considering first ( "'Problem 6 "') the effects of resistance on inertial motion in a straight line, and then ( "'Problem 7 "') the combined effects of resistance and a uniform centripetal force on motion towards / away from the center in a homogeneous medium.
32.
As far as it approaches the centre of the reverberator rotation, the amplitude of the excitation pulse is reduced, and, at a relatively low excitability of the medium there is a region of finite size in the centre of reverberator, where the amplitude of the excitation pulse is zero ( recall that we speak now about a homogeneous medium, for each point of which its properties are the same ).
