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: False
Explanation:
A hormone can have multiple function based on the cell on which it is received which means that it depends on the receptor on which the hormone is received.
A single hormone has more than one specific function as it depends on receptors because one hormone can have multiple receptors.
The same can be coupled to different intracellular pathway in the different cell types.
hence, the given statement is False, a single hormone carries out different function.
Diluents, Mannitol, Sorbitol, Dextrose, Lactose, Sucrose, Flavouring agent, Sweetening agents, Aspartame, Glycyrrhizin (Magnasweet), Saccharin, Colourants.
These are all the ingredients i know off my head I think I might be missing one or two
