Question 1

Calculate the pressure amplitude (in N/m2) of a 500 Hz sound wave in helium if the displacement amplitude is equal to 5.0 × 10−8 m. (ρ = 0.179 kg/m3, v = 972 m/s.)

◦
3.5 × 10−2

◦
1.6 × 10−2

◦
2.7 × 10−2

◦
4.2 × 10−2

◦
2.0 × 10−2


Question 2

Determine the intensity (in W/m2) of a harmonic longitudinal wave with a pressure amplitude of 8.0 × 10−3 N/m2 propagating down a tube filled with helium. (ρ = 0.179 kg/m3, v = 972 m/s.)

◦
3.7 × 10−7

◦
1.8 × 10−7

◦
9.2 × 10−8

◦
4.6 × 10−8

◦

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
