When the moving sidewalk at the airport is broken, as it oftenseems to be , it takes you 50sec to walk from your gate to baggageclaim. when it is working and you stand on the moving sidewalk theentire way, without walking, it takes you 75sec to travel thesame distance. how long will it take you to travel from the gate tobaggage claim if you walk while riding on the movingsidewalk?

Apebble is thrown into a calm lake, ripples are formed from the center and move outward. the water particles in the lake travel in a circular pattern that moves up and down on the surface of a lake, and the energy travels a) diagonally. b) downward. c) horizontally. d) upward.

Which subatomic particle has a negative charge

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.
