A transverse wave is traveling along a string that is under tension. The diagram below shows the displacement of part of the string at time t = 0 second. If the frequency of the wave is 60.0 Hz, determine the speed of the wave. 20 m/s

1800 m/s

200 m/s

18 m/s

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k
