1/ The middle-C hammer of a piano hits two strings, producing beats of 1.75 Hz. One of the strings is turned to 250.00 Hz. What frequencies (in Hz) could the other string have? (Answer to the nearest 0.1 Hz.) Hz (lower possible frequency) Hz (higher possible frequency)

2/ A transverse wave is traveling through a canal. If the distance between two successive crests is 3.47 m and four crests of the wave pass a buoy along the direction of travel every 17.6 s, determine the following.(a) frequency of the wave Hz (b) the speed at which the wave is traveling through the canal m/s

3/ Transverse waves traveling along a string have the following properties. The amplitude of the wave = 2.1 mm Wavelength of the wave = 0.12 m Speed of the wave = 368 m/sDetermine the time for the transverse displacement to travel through a total distance of 1.5 km. s

4/ A device called an insolation meter, used to measure the intensity of sunlight, has an area of 168 cm² and registers 11.4 W. What is the intensity in W/m²? W/m²

5/ The low-frequency speaker of a stereo set has a surface area of 0.04 m² and produces 2.23 W of acoustical power. What is the intensity at the speaker (in W/m²)? W/m²If the speaker projects sound uniform in all directions, at what distance (in m) from the speaker is the intensity 0.179 W/m²? m

6/What is the wavelength of the waves you create in a swimming pool if you splash your hand at a rate of 4.6 Hz and the waves propagate at 0.77 m/s? m
