shah (rps587) – HW 12 – Kleinman – (58225) 2 1. 2. correct 3. 4. 5. Explanation: Notice that the two pulses have the same width and amplitude. Choosing the the point P (the same as point Q when the two pulses coincide) as the origin, the two pulses can be described as: P : y 1 = A , - d x d Q : y 2 = braceleftBigg A , - d x < 0 - A , 0 < x < d Using the principle of superposition, the re- sultant pulse is y = y 1 + y 2 = braceleftbigg 2 A , - d x < 0 0 , 0 < x < d P Q P + Q 006 8.0 points A pulse moves on a string at 1 m/s, traveling to the right. At point A , the string is tightly clamped and cannot move. 1 m/s 1 m A Which of the following shows how the string would look soon after 2 seconds? 1. A 2. A 3. A correct 4. A 5. A 6. A
shah (rps587) – HW 12 – Kleinman – (58225) 3 7. A 8. A Explanation: The pulse travels to the right and is re- flected back from the fixed point. The wave cannot propagate to the right beyond the point A . Reflected pulses from fixed end points are inverted. 007 10.0 points In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide greater intensity. For example, the note at 136 Hz has two strings at this pitch.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
