Answer:
0.22 m
Explanation:
We are told that the driver can survive an acceleration of 50g only if the collision lasts no longer than 30 ms. So,
The acceleration is
where the negative sign is due to the fact that this is a deceleration, since the driver comes to a stop in the collision.
First of all, we can find what the initial velocity of the car should be in this conditions by using the equation:
And since the final velocity is zero, v=0, and solving for u,
And now we can find the corresponding distance travelled using the equation:
<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.
- This energy level is expressed in the form of electron configurations.
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
- In the principle of Pauli's prohibition it was stated that there are no two electrons in one atom that can have the same four quantum numbers.
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
- The electron cloud is a visual representation of the location of electrons in an atom.
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.
