The velocity of the wave is calculated by multiplying the wavelength with the frequency. It is to be noted that the unit Hz is equal to 1/s.
velocity = (wavelength)(frequency)
Substituting the known values,
velocity = (0.4 m)(2/s) = 0.8 m/s
<em>Answer: 0.8 m/s</em>
"M" I believe is the symbol for molarity.
Answer:
The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.
Explanation:
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bond
Between 0.4 and 1.7 then it is Polar Covalent Bond
Greater than 1.7 then it is Ionic Bond
For Fe and S,
E.N of Sulfur = 2.58
E.N of Iron = 1.83
________
E.N Difference 0.75 (Polar Covalent Bond)
Nitrogen followed by oxygen
