Answer:
joule
Explanation:
Let m = mass of the car and v1 = initial velocity and v2 = final velocity
Given.
Initial velocity = 100 km/h
final velocity = 50 km/h
What is work done in the car to slow it from 100km/h to 50km/h?
The work done in the car to slow it from v1 to v2.
w=Δk
joule.
Therefore, the work done is joule
<em>An electron has the same amount of energy in all orbitals is not true</em>
In an atom there are levels of energy in the skin and sub skin.
Writing electron configurations starts from the lowest to the highest sub-shell energy level.
So electrons that occupy the orbitals in the lowest sub-skin have the lowest energy level
So suppose that there are two electrons occupying one orbital can have the same main quantum number (n), azimuth (l) and magnetic (m), then the last quantum number that is the quantum spin number (s) must be different.
So that the two electrons are different from just the quantum spin number, even though the other quantum numbers are the same.
So in one orbital only a maximum of 2 electrons is occupied, because if there is a third electron, this third electron will have the same quantum spin number as the previous electron
Orbital is the place around the nucleus where electrons may be found
Electron clouds show the state of electrons in their orbitals
So electron clouds can show the condition of all orbitals in an atom
The lowest energy level of an electron occupies a sub-skin of 1s which has only one orbital
Charging electrons in the sub skin uses the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.
