The laser is passing from air into a new medium in each image. Which medium has a higher index of refraction, A or B? How do you know? * Medium A has a higher index of refraction because it is a lighter color.
Medium B has a higher index of refraction because it is a darker color.
Medium B has a higher index of refraction because the laser beam bends more.
Medium A has a higher index of refraction because the laser beam bends less.

Iwill give brainliest if you answer right : )

Carbon 14 is a naturally occurring stable

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.
