Pyranometer/ Pyrheliometer - net radiation
Explanation:
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
a)λ = 1.43 x 10⁻⁷ m, b)λ =5 x 10⁻¹⁹ and, c)λ = 1.99 x 10⁻⁷ m.
<h3>What is an atom?</h3>
- A chemical element is uniquely defined by its atoms, which are tiny pieces of substance. A core nucleus, often surrounded by one or more electrons, makes up an atom. The charge of every electron is negative. The positively charged nucleus has one or more protons and neutrons, relatively heavy particles.
- An atom is referred to any elementary particle of matter with at least one proton. Examples of atoms are neon (N) and hydrogen (H) (Ne).
- Protons, which have a positive charge, and neutrons, which have no charge, make up its structure. All regular, naturally occurring atoms contain the long-lived particles protons, neutrons, and the electrons that orbit them.
- It is difficult to appreciate how little they are until you see how many atoms there are in your body. Around 7 octillion atoms make up one adult.
a) The wavelength of the photon needed to excite an electron from E1 to E4:
ΔE = hc/λ
(-1 + 15) x 10⁻¹⁹ = 6.63 x 10⁻³⁴ x 3 x 10⁸ / λ
λ = 1.43 x 10⁻⁷ m
b) The energy (in joules) a photon must have in order to excite an electron from E2:
= (-5 + 10) x 10⁻¹⁹
λ = 5 x 10⁻¹⁹
c) An electron drops the E3 level to the E1 level, and the atom is said to undergo emission:
Change in energy = 10 x 10⁻¹⁹ J
10 x 10⁻¹⁹ = 6.63 x 10⁻³⁴ x 3 x 10⁸ / λ
λ = 1.99 x 10⁻⁷ m
The wavelength of the photon needed to excite an electron from E1 to E4 is 1.43 x 10⁻⁷ m.
The energy (in joules) a photon must have in order to excite an electron from E2 is 5 x 10⁻¹⁹.
An electron drops the E3 level to the E1 level, and the atom is said to undergo emission is 1.99 x 10⁻⁷ m.

Solids, liquids, and gases can all dissolve.
Dissolving depends on the molecules of the substance doing thedissolving, called the solvent, and the molecules of the substance being dissolved, called the solute.
Dissolving is the process in which these molecules interact and attract each other to form a solution.
Maybe a solution.
Solution- a mixture containing liquids that has a solute(Minor component) that is distributed within the solvent(Major component)...Hope that helped :)
