Explanation:
Elements can be differentiated on the basis of their spectral lines. As the spectra of any element is obtained when the electrons in the orbits of an atom change their states. When they move from lower to higher orbits they absorbs the radiation or energy. When the fall back from higher energy state to lower state they emit the radiations. Thats how the spectra of radiation is obtained. Now coming towards your question, as the different elements have different atomic numbers, they have different number of electrons in their shells. That's why the presence of the number of electrons in the shells of different elements vary. So the different number of electrons in different elements lead to the production of different numbers of spectral lines.
Answer:
La intensidad del campo eléctrico es 70312.5 
.
Explanation:
La perturbación que crea en torno a ella una carga eléctrica se representa mediante un vector denominado campo eléctrico.
Se dice que un campo eléctrico es uniforme en una región del espacio cuando la intensidad de dicho campo eléctrico es el mismo en todos los puntos de dicha región.
El campo eléctrico E creado por la carga puntual q en un punto cualquiera P se define como:
donde q es la carga creadora del campo, k es la constante electrostática y r es la distancia desde la carga fuente al punto P.
En este caso, los datos son:
- k= 9*10⁹
- q= 5*10⁻⁶ C
- r= 0.8 m
Reemplazando:
Resolviendo:
E= 70312.5
<em><u>La intensidad del campo eléctrico es 70312.5 </u></em><em><u>.</u></em>
An aptitude test is a systematic means of testing a job candidate's abilities to perform specific tasks and react to a range of different situations. The tests each have a standardised method of administration and scoring. The results are quantified and compared with all other test takers.
Answer:
