Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
Explanation:
The lewis structure looks something like this:
O=C-O ....| ...O
with the hydrogen atoms bonded to two of the Oxygen atoms. There are two other resonance structures which means that a double bond does not actual exist in the molecule. Instead there's a pair of delocalized electrons that span the entire molecule. This means that all three bonds are actually equal and thus the molecule has a trigonal planar geometry. You can also tell that it's trigonal planar because the central atom is sp2 hybridized.
Answer:
f = 0.534×10⁻² Hz
Explanation:
Given data:
Frequency of wave= ?
Wavelength of wave = 5.62×10¹⁰ m
Solution:
Formula:
Speed of wave = wavelength × frequency
Speed of wave = 3×10¹⁷ nm/s
λ = 5.62×10¹⁰m×10⁹ nm/1 m = 5.62×10¹⁹ nm
Now we will put the values in formula.
3×10¹⁷ nm/s = 5.62×10¹⁹ nm × f
f = 3×10¹⁷ nm/s / 5.62×10¹⁹ nm
f = 0.534×10⁻² s⁻¹ or
f = 0.534×10⁻² Hz
