When astronomers observe the spectra of distant galaxies, they notice that the hydrogen emission lines are shifted noticeably toward the red end of the visual spectrum, a phenomenon called red shift. red is the lowest frequency of visible light. what does red shift indicate about the movement of the distant galaxies? they are moving away fro us at high speed. they are moving towards us at high speed. they are moving in the same direction as we are. they are motionless, while we are moving toward them at high speed.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
