1. A steel cable with total length 34 m and mass 130 kg is connected to two poles. The tension in the cable is 2,829 N, and the wind makes the cable vibrate with a frequency of 2 Hz. Calculate the wavelength of the resulting wave on the cable. m

2. In a student laboratory exercise, the wavelength of a 28,300 Hz ultrasound wave is measured to be 1.205 cm. Find the air temperature (in K). K

3. A person stands directly in front of two speakers that are emitting the same pure tone. The person then moves to one side until no sound is heard. At that point, the person is 3.90 m from one of the speakers and 3.94 m from the other. What is the frequency (in Hz) of the tone being emitted? (Assume air temperature to be 20C.) Hz
