Question
I JUST NEED NUMBER 1 AND 4 answered. thanks.
In the space provided. show that the shape of the spring al 1*03% (determined by using your model for free-end reflection) is not consistent with the correct boundary condition for this case. diagram at night shows two pulses. One Km/reflected from a fixed end: the other, from free end. The diagram has several errors. Describe each error that you can find. Note that the peak of the pulse is drawn as a sharp "kink" in the spring. How does this kink" lead to the inconsistency mentioned above1 Two pulses on opposite sides of a spring ^y moving toward each other. The diagrams below show the pulse locations at four successive instants. each diagram, sketch the shape of the spring for the instant shown. A pulse is moving toward the end of »spring that is attached to a wall. The diagram at right shows the pulse Jl ' = 0J3 s. The leading edge of the pulse reaches the wall at / = 0.4 s. I" the spaces provided below right, carefully draw the shape of the spring at i = 0.8 s and '= 1.2 s. (Note: The pulse is in the Process of being reflected at ' = 0.8 s.) n the space below, explain the %,CP* that you followed in part a in order determine the shape of spring.
