PLEASE HELP WITH EXPLANATION! I WILL GIVE YOU BRAINLIEST! Calculate the average velocity of a dancer who moves 5 m toward the left of the stage over the course of 15 s.

What happens to light waves from a star as the star moves away from earth?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

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.)
