Question: When an aircraft is flying at subsonic velocity, the pressure at its nose, i.e., at the stagnation point, is found to be 160 kPa. If the ambient pressure and temperature are 100 kPa and 25°C, respectively, find the speed and the Mach number at which the aircraft is flying.
The wave function for a wave on a taut string is y(x, t) = 0.335 sin(9?t ? 3?x + ?/4) where x and y are in meters and t is in seconds. What is the energy contained in each cycle of the wave
