A rock group is playing in a bar. Sound emerging from the door spreads uniformly in all directions. The intensity level of the music is 115 dB at a distance of 3.58 m from the door. At what distance is the music just barely audible to a person with a normal threshold of hearing? Disregard absorption. Answer in units of m.

A wire of length L₁ = 30 cm has one end fixed and the other end welded to another wire, whose linear density of mass is 4 times smaller. The second wire passes through a pulley and a mass of 10 kg is suspended by its other end. The distance L₂ between the weld point and the pulley is 80 cm. A stationary wave is produced in the composite wire, whose ends at the left wall and the pulley remain fixed. If the frequency is as low as possible and there is one node (node) at the solder point, what is the number of nodes (nodes) of this stationary wave, including the nodes (nodes) at the left wall and the pulley? a. 3b. 4c. 5d. 6e. 7f. 8g. 9h. 10a. 11j. 12k. 13l. 14m. 15

If the vertical gap 2.2-cm wide of infinite extent contains a fluid with specific gravity of 0.9. A metallic plate 1.2m x 1.2m x 0.2cm is to be lifted up with a constant velocity of 0.65 - m/sec, through the gap. If the plate is in the middle of the gap and the total force to lift the plate up is 150-N, what is the damping coefficient of the system.

Determine the intensity meter error when measuring the intensity of a sound wave having a frequency of 2 kHz in air with a sonic velocity of 344 m/s (1129 fps). The spacer thickness is 12 mm (0.472 in). The measured overall sound pressure level around an electric motor (including background noise) is 73.6 dB. The measured background sound pressure level is 71.1 dB. Determine the sound pressure level for the electric motor alone (background noise removed).
