Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m. Which statement accurately describes something that Yolanda can do as a part of her study?

She can use destructive interference to generate a wave with an amplitude of 3.1 m.
She can use constructive interference to generate a wave with an amplitude of 1.5 m.
She can use destructive interference to generate a wave with an amplitude of 0 m.
She can use constructive interference to generate a wave with an amplitude of 3.5 m.

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud

True or false graphs must include scales that increase by the same amount

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.
