A student performs an experiment with two springs. A and E. attached end-to-end at point 1 as shown below. The student creates pulses by moving spring A quickly back and forth. M. Vinum ' Wall Spring A 1 Spring B J The student notes that pulses travel more quickly in spring A than in spring B. a. Is the tension in spring A (1\") greater than. less than. or equal to the tension in spring B (Ts)? Explain. If it is not possible to make this comparison. explain why not. b. Is the mass per unit length of spring A (pa) greater than. less than. or equal to the mass per unit length of spring B my)? Explain. If it is not possible to make this comparison, explain why not. 2. The student generates an asymmetric pulse in spring A that moves to the right as shown below. Spring A- Spring B- On the diagram below, sketch the shape of spring A and spring B a short time after the entire pulse has reached the junction, J, between the two springs. Spring A Spring B- Describe in words what happens when the pulse reaches the junction, J
