Answer:
You can use a sound velocity probe
The unit 'mW' means milliwatts. It is a unit of work. There are 1,000 milliwatts in a 1 Watt of work. In 4 hours, there are 14,400 seconds.
Work= Energy/time
17 mW * 1 W/1000 mW = Energy/(14,400 seconds)
Solving for energy,
Energy = 244.8 J
Energy/photon = 244.8 J/(6.04×10²⁰) = 4.053×10⁻¹⁹ J/photon
Using the Planck's equation:
E = hc/λ
where h = 6.626×10⁻³⁴ m²·kg/s, c = 3,00,000,000 m/s and λ is the wavelength
4.053×10⁻¹⁹ J/photon = (6.626×10⁻³⁴ m²·kg/s)(3,00,000,000 m/s)/λ
λ = 4.9×10⁻⁷ m or 49 micrometers
The soap cannot be expected as a good rust remover, as it lacks the presence of strong acids, or petroleum products, to dissolve the rust.
<h3>What is rusting?</h3>
Rusting is the process of the formation of iron compounds with the reaction of iron with oxygen and water.
The rust can be removed with the acid and petroleum products, as their reaction dissolves the oxygen compounds.
The soap alone cannot be considered a good rust remover, as it lacks the presence of strong acids or petroleum products to dissolve the rust.

H2O has a bent structure. The oxygen atom is in the center, and the hydrogen atoms are attached but pointing downward. It's not linear because there are two unshared pairs of electrons on oxygen that take up their own spaces.
