A stretched cord has a fundamental frequency of 144 Hz, a length of 0.9 m, and a mass of 2 g. What is its wave speed? O 65 m/s O 130 m/s O 259 m/s O 1037 m/s O 80 m/s

We used an experimental setup like the one shown below. The length of the string between the string vibrator and the pulley is L = 2.00 m. The mass per unit length or linear density of the string is μ = 0.0005 kg/m. The string vibrator can oscillate at any frequency. The hanging mass is 511 g. Frictionless pulley String vibrator μl= dm dx The wavelength of the fifth mode (n = 5) is m. The frequency of the fifth mode (n = 5) is Hz. The tension in the string is close to When the mode of vibration is increased to n = 10, the wave speed of the string will → 2 The wave speed on the string is m/s.

A wave has a wavelength of 30 cm. What is the phase difference between two points on this wave that are 45 cm apart? π/4 rad π/3 rad π/2 rad 2π/3 rad π rad

A string that has a mass per unit length of 0.003 kg/m is under a tension of 2.00 N. What would be the speed of a wave on this string? 0.006 m/s O 1.5 m/s 25.8 m/s 667 m/s
