1. Preliminary QuestionsNote:You will receivefull credit for each predictionmade in this preliminary section whether or not itmatches conclusions you reach in the next section. As part of the learning process it is important to compareyour predictions with your results.Do not change your predictions!(a)Examine how a coil moves as a transverse wave passes along the spring:Open the LoggerProfile <CoilMotion.cmbl>, which has the movie <SlinkyWave_T01(hi-speed).mov> inserted. In frame 14of the movie, the y-axis is set to pass through a spring coil that is not yet disturbed. Please examinehow this coil moves in the x-and y-directions, if at all, at various times as the wave travels along thespring. Please put an X in each box that describes the motion of the coil during the frames listed in thecolumn.xxxxx
(c)How do you think the speed of the transverse disturbance,vw, would change, if at all, if the springwere stretched further so that it has a greater tension,T, and smaller mass per unit length, µ?Explainthe reason(s) for your answer.
(d)How to you think the speed of the transverse disturbance would change, if at all, if another springis used that has the same tension but thicker, more massive coils so that its mass per unit length,µ, isincreased?Explain the reason(s) for your answer.
