Answer:
One of the main functions lipids do is storing energy.
provide the building blocks for muscle tissue
1. This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning.
2. Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
3.According to this law the expression P2a−3 has the same value for all the planets in the solar system. Here P is the time taken for a planet to complete an orbit round the sun, and a is the mean value between the maximum and minimum distances between the planet and sun
4. When a planet or moon travels once around an object this is considered a revolution.
5. The lunar phase or phase of the moon is the shape of the illuminated (sunlit) portion of the Moon as seen by an observer on Earth. The lunar phases change cyclically as the Moon orbits the Earth, according to the changing positions of the Moon and Sun relative to the Earth.
Answer:
λ = 6.25 × 10⁻¹⁰ m
x-ray
General Formulas and Concepts:
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
C = 3.0 × 10⁸ m/s
ν = 4.80 × 10¹⁷ Hz (s⁻¹)
λ = unknown
<u>Step 2: Solve for wavelength</u>
3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)
λ = 6.25 × 10⁻¹⁰ m
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
6.25 has 3 sig figs. No changes necessary.
<u>Step 4: Identify</u>
6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum
The electron configuration filling patterns of some elements in group 6b(6) and group 1b(11) reflect the increasing stability of half-filled and completely filled sublevels.
<h2>
What is electronic configuration?</h2>
The distribution of electrons in an element's atomic orbitals is described by the element's electron configuration. Atomic subshells that contain electrons are placed in a series, and the number of electrons that each one of them holds is indicated in superscript for all atomic electron configurations. For instance, sodium's electron configuration is 1s22s22p63s1.
Almost all of the elements write their electronic configurations in the same style. When the energies of two subshells differ, an electron from the lower energy subshell occasionally goes to the higher energy subshell.
This is due to two factors:
Symmetrical distribution: As is well known, stability is a result of symmetry. Because of the symmetrical distribution of electrons, orbitals where the sub-shell is exactly half-full or totally filled are more stable.
Energy exchange: The electrons in degenerate orbitals have a parallel spin and are prone to shifting positions. The energy released during this process is simply referred to as exchange energy. The greatest number of exchanges occurs when the orbitals are half- or fully-filled. Its stability is therefore at its highest.
