You walk forward at 1.5 m/s for 8s. your friend decides to walk faster and starts out at 2.0 m/s for the first 4 s. then she slows down and walks forward at 1.0 m/s for the next 4s. make a distance-time graph of your motion and your friend's motion. who walked farther?

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

In an experiment, how can i change human errors? be specific.

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.
