The diagram shows parts of a wave. A series of waves with an arrow passing through their centers. The highest point of one wave is labeled X. The lowest point of another wave is labeled Y. A bracket labeled Z connects the highest points of 2 waves. Which is shown by the letter X? trough amplitude crest wavelength

Observations show that interstellar clouds can have almost any shape and

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
