16.6: a) The time for the wave to travel to Caracas was s 579 s 39 min 9 = and the speed was s m 10 085 . 1 4 × (keeping an extra figure). Similarly, the time for the wave to travel to Kevo was 680 s for a speed of s, m 10 278 . 1 4 × and the time to travel to Vienna was 767 s for a speed of s. m 10 258 . 1 4 × The average speed for these three measurements is s. m 10 21 . 1 4 × Due to variations in density, or reflections (a subject addressed in later chapters), not all waves travel in straight lines with constant speeds.

Unformatted text preview: b) From Eq. (16.7), , 2 ρ v B = and using the given value of 3 3 m kg 10 3 . 3 × = and the speeds found in part (a), the values for the bulk modulus are, respectively, Pa. 10 2 . 5 and Pa 10 5.4 Pa, 10 9 . 3 11 11 11 × × × These are larger, by a factor of 2 or 3, than the largest values in Table (11-1)....

    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.
