2. An airplane has an air velocity of 200 m/s (W). The wind velocity relative to the ground is 60 m/s [N]. K/U TAA (a) Determine the velocity of the airplane relative to the ground. (b) The airplane now faces a headwind of 60 m/s [E]. Calculate how long it takes the airplane to fly between two cities 300 km apart.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
