Final answer:
To find the speed of the wave, we use the formula v = √(T/μ), where T is the tension in the string and μ is the linear density of the string. In part (a) of the drawing, the wave speed is 8.94 m/s. In part (b), the wave speed cannot be determined without the tension.
Step-by-step explanation:
In order to find the speed of the wave, we can use the formula:
Wave speed (v) = √(T/μ)
where T is the tension in the string and μ is the linear density of the string.
In part (a) of the drawing, the tension is provided by a 26-N block. We can calculate the wave speed using the given tension and linear density:
v = √(26 N / 0.065 kg/m) = 8.94 m/s
In part (b) of the drawing, the tension is not given. Therefore, we cannot determine the wave speed without knowing the tension.
