A string of length 0.67 m and mass 2.0 g is held at both ends under tension. The string produces a 700 Hz tone when it vibrates in the fourth harmonic. During this event, what is the
wavelength of the standing wave in the string?

.34
.55
.61
.45
.49

The value is  

Explanation:

From the question we are told that

     The length of the string is  

      The mass is  

      The frequency produced at  fourth harmonic vibration(i.e n =4 )  is  

  Generally the wavelength of the string is  mathematically represented as

=>            

=>            

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
