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
Breathe in slowly and deeply through the
mouthpiece. At the same time, press down once
on the container to spray the medication into your
mouth. When you have breathed in fully, remove
the inhaler from your mouth and close your mouth.
Try to hold your breath for about 5 to 10 seconds,
then breathe out gently.

Qid is a medical term meaning 4 times a day, and 1 gm= 1,000 mg.
Given what we know about rheumatoid arthritis, we can confirm that the nurse can determine that the teaching is effective when the client makes the statement that "<em>Rheumatoid arthri</em><em>tis includes </em><em>joint involvement </em><em>that is usually </em><em>symmetric </em><em>and </em><em>polyarticular</em>".
Arthritis is one of many diseases in the autoimmune category. An autoimmune disease is one in which the immune system of the patient attacks its own cells. <em><u>The reasons behind this remain unknown</u></em>. In the case of Rheumatoid arthritis, the attacks remain isolated to the joints. The immune system causes the joints to be unable to produce synovial liquid, which causes inflamation.
As stated by the patient, Rheumatoid arthritis includes joint involvement that is usually symmetric and polyarticular. What this means is that any diarthrodial joint can be affected by the condition and is usually collateral, meaning that <u>if the left hand is affected, the right hand often is as well.</u>
