This question contains multiple parts. Make sure to read all the instructions and answer each part. A bow slides across a violin string that has length 31.7cm and mass 0.140g. The string vibrates at its fundamental frequency to produce the musical note A (440Hz) Part a (1 points) How does the frequency of wave in the string compare to the frequency of the sound wave in the air? Select the correct answer CHECK ANSWER Saved 2 of 3 checks used LAST ATTEMPT! O They both have the same Your frequency Answer The sound wave has a higher frequency than the wave in the string The answer depends on the temperature of the air and the tension in the string The sound wave has a lower frequency than the wave in the string (1 points) Part b What is the wavelength of the wave on the violin string?

The tension in the cable is 454 N. The distance between poles is 11.1 meters. The wind blows across the line, causing the cable to resonate. A standing waves pattern is produced that has 4.5 wavelengths between the two poles. What is the frequency of the hum? Please enter a numerical answer below.

The middle (D) string on the guitar should have fundamental frequency 146.83 Hz. The highest (E) string should have fundamental frequency 329.63 Hz. If the D string has linear mass density 0.00370kg/m, what should be the mass density of the E string? Assume all the strings are the same length. Give your answer with at least 3 significant digits.
