Answer:
E₁ = 1.042 eV
E₄₋₃= 7.29 eV
E₄₋₂= 12.50 eV
E₄₋₁= 15.63 eV
E₃₋₂= 5.21eV
E₃₋₁= 8.34eV
E₂₋₁= 3.13eV
Explanation:
The energy in an infinite square-well potential is giving by:
<em>where, h: Planck constant = 6.62x10⁻³⁴J.s, n: is the energy state, m: mass of the electron and L: widht of the square-well potential </em>
<u>The energy of the electron in the ground state, </u><u>n = 1</u><u>, is: </u>
The photon energies that are emitted as the electron jumps to the ground state is the difference between the states:
Have a nice day!
Answer:
Push or Pull Forces - example
When you push against a wall the force that you exert is an example of a push force. When you pull a trolley car the force that you exert is an example of pull force.
Answer:
1. In general, the best shields will be able to block a spectrum of radiation. Aboard the space station, the use of hydrogen-rich shielding such as polyethylene in the most frequently occupied locations, such as the sleeping quarters and the galley, has reduced the crew's exposure to space radiation.
2. It absorbs harmful ultraviolet radiation from the sun, helps keep Earth's surface warm via the greenhouse effect, and reduces temperature extremes between day and night. ... So, thanks to gravity, although some of Earth's atmosphere is escaping to space, most is staying here.

Answer:
V=3 m/s
t=12 seconds
S=?
S=V×t
S=3×12
S=36meters
So distance you travel is 36meters.
Answer:
Evaporation
Explanation:
Evaporation is a form of mass tranfer phenomena where by water are moved from the earth surface into the atmosphere as vapours,it is path of the water cycle a decription of the path moved by land water until it turns into rain, humidity,air and temperature are factors that influence evaporation though evaporation can happen at all temperature
