6. Two identical speakers are emitting sound of the same frequency. Speaker 1, located 5 m away, has a sound level of 76 dB. Speaker 2, located 10 m from you, has a sound level of 73 dB. Assuming spherically radiating sound waves, which of the two speakers is producing the sound at higher power?
7a. Express the fundamental frequency of a piano wire fixed at both ends in terms of its tension FT, length L, radius r, and the 3D mass density ρ of the wire material.
7b. Given: radius r = 0.375 × 10-3 m, length L = 0.501 m, and ρsteel = 7.86 × 103 kg/m3. What is the tension required for a steel piano string tuned to middle C (f = 261.626 Hz)?
