Answer:
Wavelength = 64.635 pm
Explanation:
The expression for the deBroglie wavelength and kinetic energy is:
Where,
is the deBroglie wavelength
h is Plank's constant having value 
m is the mass of electron having value 
K.E. is the kinetic energy of the electron.
Given, K.E. = 360 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.6022 × 10⁻¹⁹ J
So, K.E. = 
Applying in the equation as:
Also, 1 m = 10¹² pm
<u>So, Wavelength = 64.635 pm</u>
Answer:
the answer is atmospheric carbon dioxide
Explanation:
Explanation:
Pumice is an extrusive igneous rock that is produced through volcanic activities.
A rock like pumice will pass through the rock cycle and be transformed to other rock types with time.
Pumice contains rich mafic minerals giving it that black appearance.
The consequences of this is that when the rock is acted upon by weathering elements, it is weathered to clay. A fine grained sediment. It will eventually be transformed to shale or claystone sedimentary rocks.
If is goes through the metamorphic path, a schist will form under conditions of high pressure and temperature. New minerals will grow and metamorphic transformation would be vivid.
Eventually, both sedimentary and metamorphic rocks can be subducted and will form the original melt again.

It’s gonna be water and wind after many years of harsh winds and water the rock will slowly start to break or even become smooth ! That’s why you might find those at the lake ! so c!
Answer:
Option D is correct.
n = 6 to n = 2
Explanation:
Like all waves emitted from the movement of electrons from one energy level to another, the wavelength (λ) is given by the equation involving Rydberg's constant
(1/λ) = Rₕ [(1/n₂²) - (1/n₁²)]
where Rₕ = 10973731.57 m⁻¹ = (1.0974 × 10⁷) m⁻¹
n₂ = principal quantum number corresponding to the final energy level of the electron = 2 (For Balmer Series)
n₁ = principal quantum number corresponding to the final energy level of the electron = ?
λ = 410 nm = (410 × 10⁻⁹) m
(1/λ) = (2.439 × 10⁶) m⁻¹
2.439 × 10⁶ = (1.0974 × 10⁷) [(1/2²) - (1/n₁²)]
0.25 - (1/n₁²) = (2.439 × 10⁶) ÷ (1.0974 × 10⁷) = 0.2222602562
(1/n₁²) = 0.25 - 0.2222602562 = 0.0277397438
n₁² = (1/0.0277397438) = 36.05
n₁ = 6
Hope this Helps!!!
