Atransport aircraft whose wing span is 35.8 m is flying at 262 kts at an altitude where the lateral relative density parameter i2= 24.4. the dimensionless controls-fixed lateral directional characteristic equation is 4 5.8 20.32 + 79.0 0.37 = 0 (a) what can be deduced about the lateral-directional stability of the aircraft from inspection of the characteristic equation? (b) solve the characteristic equation approximately; determine estimates for the time constants of the nonoscillatory modes and the frequency and damping ratio of the oscillatory mode (c) comment on the acceptability of this aircraft

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

Which sections of the heating curve illustrate this process?

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
