Answer : A. Location A
The seats in location A will experience sound waves with the greatest intensity , because it is closer to the stage .
The average atomic mass of the imaginary element : 47.255 amu
<h3>Further explanation </h3>
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
isotope E-47 47.011 amu, 87.34%
isotope E-48 48.008 amu, 6.895
isotope E-49 50.009 amu, 5.77%
The average atomic mass :
<span>4.66 x 10^-19 Joules
The energy of a photon is
E=hf
Where
E = Energy
h = Planck's constant (6.62607004Ă—10â’34 J s)
f = frequency of photon.
So plug in the known values
E = 6.62607004Ă—10â’34 J s * 7.03 x 10^14 1/s
E = 4.65812724x10^-19 J
Since we only have 3 significant figures, the rounded result is
E = 4.66x10^-19 J</span>
Answer:
C). Electronegativity.
Explanation:
'Electronegativity' is described as the tendency or a measure of the ability of an atom or molecule to attract electrons that leads to the formation of chemical bonds. It is denoted by 'χ', a Greek letter. The elements like Fluorine having a very high rate of electronegativity, its atom would attract the electrons more strongly while the elements with lesser electronegativity like Cesium would possess a lesser tendency to attract electrons towards it in order to form a bond. Thus, <u>option C</u> is the correct answer.
