How does the shift observed in the light from a galaxy relate to the distance of the galaxy from earth? a. the greater the distance, the more light is redshifted. b. the greater the distance, the less light is redshifted. c. at a great enough distance, the light becomes blueshifted. d. there is no relationship between the shift and the galaxy's distance from earth.

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.
