In an earlier physics course you learned about waves (sound waves, waves on the strings of musical instruments, etc.). Describe the main difference between longitudinal waves and transverse waves.(2 pts)Based on what you have learned in the lecture part of the course, which of these two types is an electromagnetic wave(2 pts)

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.
