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
cheers i hope this helps
Answer:
Thyroid cartilage
Adam's apple
Explanation:
Adam's apple is a cartilaginous structure that protrudes from the anterior angle of the thyroid cartilage located at the level of the larinx, Adam's apple is more prominent in men due to the hormonal influence of testosterone, so it is related in the developing of the deeper voice tone of the males.

Answer: Decrease in blood pressure
Explanation:
If there is increase in atrial vessel diameter then, the blood pressure is conversely decreases. Peripheral resistance and increase in blood volume diameter are responsible for higher the blood pressure. The peripheral resistance are responsible for blood flow in the arteries.
There are three sources of the peripheral resistance are:
- Total length of vessel
- Blood viscosity
- Diameter of blood vessel
