Answer:
The net energy is 2.196 eV
Explanation:
Basically, the energy of an atom increases when it absorbs a photon. In addition, the wavelength of the emitted photon is longer such that the atom absorbed a net energy in the process.
Using:
ΔE = h*c*(1/λ
- 1/λ
)
where:
ΔE is the net energy in eV (electron-volt). 1 eV is equivalent to 1.602*
J.
h = 4.135*
eVs
c = 3*
m/s
λ = 300 nm = 300*
m
λ = 640 nm = 640* m
Thus:
ΔE = 4.135* eVs*3* m/s*(
)
ΔE = 4.135**3**1.77*
eV = 2.196 eV
Mary thinking her astrological sign, Leo, is a perfect fit for her personality is a belief in pseudoscience because there is not scientific evidence confirming such beliefs.
The answer is the second option.
Solar flare: a brief eruption of intense high-energy radiation from the sun's surface, associated with sunspots and causing electromagnetic disturbances on the earth, as with radio frequency communications and power line transmissions.
Sunspot Prominence: It is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. It is similar to a Solar Flare
Hope this help
Answer:
C solution
Explanation:
i hope that i got it right im not very good with questions
I'm obsessed with me as much as you
Say you'd die for me I'd die for me too
