It doesn’t let me see the picture it’s blurry.
Divide it by avagardo's constant that should work as its the number of particles.
Answer:
50m/s
Explanation:
The formula for calculating speed of wave in relation to frequency and wavelength is
C=λf
Where c is the speed of the wag
λ is the wavelength which is 1m
f is the frequency which is 50Hz
From the formulas,
C= 50X1
C= 50m/s
