Answer:
2.72 m
Explanation:
Sound travels at a certain speed and has a frequency and wavelength. The relationship between the speed of sound (V), its frequency (f), and wavelength (λ) is the same as for all waves, it is given by the equation:
V = fλ
The speed of sound in air (V) is 334 m/s
Frequency of sound (f) = 123 Hz
Wavelength = λ
V = fλ
λ = V/f = 334/123
λ = 2.72 m
There are 2 atoms of nitrogen in this chemical formula
We know this because outside the bracket, there is a 2 which means everything inside the bracket is multiplied by that 2, meaning there will be 2 atoms of nitrogen and 6 atoms of oxygen.. And 1 atom of nickel as nickel isn't included inside the brackets
