Answer:
-8
Explanation:
sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.
X-ray formation
Energy difference in the first ionization of the same group of elements
Differential linear emission spectra of different elements
Explanation:
The formation of x-ray, energy difference in the first ionization of the same group of elements and differential linear emission spectra of different elements can be justified by the Bohr model of the atom.
- According to Neil Bohr, in an atom, the extranuclear part consists of electrons in specific spherical orbits around the nucleus.
- Bohr's model explained the discrete lines in atomic spectrum of different elements.
- Due to excitation of electrons, some rays are given off. Some of these are energetic like x-rays.
- The energy difference between the first ionization of the same group of elements is a proof that electrons are in specific spherical orbits.
- The higher the energy the level, the ease at which electrons can be removed and the lower the ionization energy.

Electric Field Strength E = Force F/ Charge q
E = F/q
Force , F = E*q
But charge on an electron q = 1.6 * 10⁻¹⁹ C
E = 3 * 10³ N/C from the question.
Force F = 3* 10³ * 1.6 * 10⁻¹⁹
F = 4.8 * 10⁻¹⁶ N.
Electrostatic force F = 4.8 * 10⁻¹⁶ N
