Answer: Δβ = 28.5278 dB
Explanation:
from the question we are given that;
the sound gathering area Ga = 15.0 cm²
total area Ae = 0.800 cm²
efficiency ε = 38 %
therefore we have that the effective gathering area of the stethoscope is;
As = ε Ga
As = 38 % × 15 = 5.7 cm²
But I ∝ 1/A
where Ie/Is = As/Ae
Ie/Is = 5.7/0.800 = 7.125
given that we are to assume that sound is transmitted into a stethoscope 100 times, this gives
I'e/I's = Ie/Is × 100 = 7.125 × 100 = 712.5
Δβ = βe - βs = (10dB) log (I'e/Io) - (10dB) log (I's/Io)
Δβ = (10dB) log (I'e/I's)
Δβ = (10dB) log (712.5) = 28.5278
Δβ = 28.5278 dB

Answer:
The answer is: <u>horizontal plate of</u><u> </u><u>palatine bone</u> and <u>palatine process</u> of the maxilla bone.
Explanation:
The nasal cavity is the bilateral air-filled space present above the roof of the mouth and behind the nose, that forms the interior of the nose.
The hard palate forms the roof of mouth and floor of the nasal cavity. The bones of the hard palate that are present on the <u>floor of nasal cavity </u><u>are the horizontal plate of</u><u> palatine bone</u><u> and </u><u>palatine process</u><u> of the maxilla bone.</u>
Answer: Oviparity, expulsion of undeveloped eggs rather than live young. The eggs may have been fertilized before release, as in birds and some reptiles, or are to be fertilized externally, as in amphibians and many lower forms
