What type of motion is illustrated in the diagram below?
A. Oscillating motion faster than the speed of sound.
B. Oscillating motion slower than the speed of sound.
C. Circular motion faster than the speed of sound.
D. Circular motion slower than the speed of sound.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

Afrequency generator sends a 550 hz sound wave through both water and ice. what is the difference in wavelength between the wave produced in ice and the wave produced in water?

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.
