Quizplus · Accepted Answer

The velocity of spherical waves in a homogeneous medium is given by v = √(E/ρ), where E is the Young's modulus and ρ is the density of the medium. As no information is given about the medium, we assume it to be air, which has a Young's modulus of 1.4 x 10^11 N/m^2 and a density of 1.2 kg/m^3. Substituting these values in the formula gives v = √(1.4 x 10^11 N/m^2 / 1.2 kg/m^3) ≈ 340 m/s. Therefore, the correct answer is C.
