Velocity = fλ
where f is frequency in Hz, and λ is wavelength in meters.
2.04 * 10⁸ m/s = 5.09 * 10¹⁴ Hz * λ
(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴ Hz ) = λ
4.007*10⁻⁷ m = λ
The wavelength of the yellow light = 4.007*10⁻⁷ m
Answer:
Air drying
Explanation:
Sanitation is the set of measures that aims to preserve or modify the conditions of the environment in order to prevent diseases and promote health, improve the quality of life of the population and the productivity of the individual and facilitate economic activity. Basic sanitation is a right guaranteed by the Constitution as the set of services, infrastructure and operational installations for water supply, sanitary sewage, urban cleaning, urban drainage, solid waste and rainwater management.
Sanitation can be carried out in several ways, except for dry air, as this would damage the quality of sanitation and the environment.
Sanitation is important in treated water, sewage collection and treatment services lead to an improvement in the quality of people's lives, especially in child health, with a reduction in child mortality, improvements in education, in the expansion of tourism, in the valuation of properties, in income of the worker, in the cleaning of rivers and preservation of water resources, etc.
Answer:
Just to help, periods on the periodic table are those running horizontally from left to right
The believe that the best answer among the choices provided by the question is a small nucleus with electrons moving around it
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
If it gains three electrons then it means it's a negative 3 because when it's positively charged then you lose electrons but when it's negatively charged then you gain electrons. It's reversed. Electron Configuration would be 1s2, 2s2, 2p3 that's without gaining the three electrons. With it is 1s2, 2s2, 2p6 which means that the Noble Gas is Neon.
