Answer: 83.17
Explanation:
By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.
It applies specifically to power, and it is defined as follows:
P (dB) = 10 log₁₀ P₁ / P₂
Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.
In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.
Applying the dB definition, we can write the following:
10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92
Solving the logarithmic equation, we can compute X as follows:
X = 10^1.92 = 83.17
X = 83.17
Answer:
1.6666 g/mol = 1
g/mol
Explanation:
Molar mass of NaOH= 23+16+1 =40g/mol
Mols in 15g = 15/40 mol
If this was dissolved in 225ml of water molarity of the solution is
÷ 225 x 1000 = 1.6666 g/mol = 1
g/mol
The closest line to that would be the first line:
#!/bin/bash
echo "Hello World!"
BTW, the "#!" is referred to as a she-bang. When those are the first characters executed, the (requires an absolute path) program that follows is launched, and the rest of this file is given to it as data. To run this like a program, the execute permissions need to be set ( chmod 0755 script.sh ).

Answer:
Music can evolve by the process of natural selection, the same way species evolve in the natural world. They found that the loops quickly evolved into music attributable, in part, to the evolution of aesthetically pleasing chords and rhythms.
