Honors Physics - Final Exam Review with Complete Solutions What is the principle of superposition in wave interference? The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves' amplitudes. How does the frequency of a wave relate to its wavelength? The frequency of a wave is inversely related to its wavelength; as the frequency increases, the wavelength decreases, and vice versa. What is the role of an ele...

Vertical line on right side - Redline Airspeed, Velocity Never to Exceed As these vortices continue aft of wing, they continue as spiraling masses of air (Jet wash, Wake Turbulence) What three things happen as air becomes less dense for airplane: - Reduces power Reduces thrust Reduces lift Moment - Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") When are the four forces that act on an airp...

Physics SLO Test Review The SI unit of length, the meter, is currently defined - as the length of the path traveled by light in a vacuum during 1/ s. The SI unit of mass, the kilogram, is currently defined - by a prototype platinum-iridium cylinder kept at the International Bureau of Weights and Measures in Sevres, France. The SI unit of time, the second, is currently defined by - a duration of an atomic clock Which of the following is a megawatt? - 10^6 W Which of the following...

rigid body - object of non-zero size that cannot change shape position - location and orientation CoG - average location of all weight of an object (typically in midline a bit below navel of humans) orientation in space - position with respect to the points of a compass or other directions motion of rigid body - change in position denoted by its location and orientation at every instant in time) distance - total distance travelled (SI unit: m) displacement - how far an object is from i...

NIFE AERO QUESTIONS AND ANSWERS RATED A+ What is a vector? direction and magnitude What is air density? Total mass of air particles per unit volume. m/v What is a moment? Force that is moved some distance. What are the requirements for an airplane to be in equilibrium flight? Sum of all forces and all moments around the center of gravity are equal to 0 Can equilibrium flight be achieved in a turn? No. Acceleration is occurring. There are moments What are the requirements for an a...
