Match the string with its note.   While there is a range of tensions used to tune the strings, they are roughly the same and differ by only 20%.  The strings shown are from a real guitar used to play acoustical music.  Masses are given in grams per meter.                                                             E 330 Hz                                                             B 247 Hz                                                             G 196 Hz                                                             D 147 Hz A. 1.62 g/m B. 0.477 g/m C. 0.309 g/m D. 1.03 g/m

Figure below shows a standing wave in string with L = 30 cm. If the wave has a frequency of 240 Hz, what is its speed? ○ 8 m/s ○ 144 m/s 36 m/s ○ 800 m/s 72 m/s ○ 28.8 m/s ○ 48 m/s L

A piano has the widest range of notes of any instrument. It achieves this large range using both the length and mass density, H, of the strings. In a real piano, most of the strings have roughly the same tension. We shall assume that all the strings in our piano have a tension of T = 760 Newtons. L1 L1 is the longest string L88 is the shortest string L27 Bass strings L26 Line of strike Treble strings L88 Grand Piano Details Grand Piano Simplified We shall assume the following regarding the longest and shortest strings in the piano: String frequency (Hz) length (m) tension (N) L1 27.5 0.163 760 L88 4186.01 0.046 760 Calculate all the following: The linear mass density of the L1 string: µ1 = kg/m %3D The linear mass density of the L88 string: µ88 = kg/m As you likely calculated, the L1 string has a much higher u than the L88 string. If you have ever looked inside a piano you know this to be true. For the next calculation we are going to do something silly. We will calculate how long a…

An Ethernet cable is 4.30 m long. The cable has a mass of 0.205 kg. A transverse pulse is produced by plucking one end of the taut cable. The pulse makes four trips down and back along the cable in 0.795 s. What is the tension in the cable?
