Alfisols can be found in humid areas and semiarid areas. They are formed in forest and savanna vegetation. They are very fertile and productive soils. These soils contains high concentrations of nutrient that are cations like calcium, magnesium, potassium and sodium.
Blue would bend the most, since it has a greater refractive index. It has more energy and a shorter wavelength, so it slows.
Answer:1.9 meters
Explanation:
Wavelength=velocity ➗ frequency
Wavelength=18.81 ➗ 9.9
Wavelength=1.9
Wavelength is 1.9 meters
Well if the child weighs 44 kg then 44 kg. Do you mean if they weigh 44 kg in space to earth?
The wave travels at the speed of sound in water:
.
The frequency of the wave is
so we can find its wavelength
by using the basic relationship between frequency, wavelength and speed of the wave:
