After they have gathered enough information by testing the theory.
Im pretty sure that the first modle had the atom fully solid with no gaps!
Answer:
Puesto que la energia cinética traslacional es mucho mayor que la capacidad del chaleco antibalas, la bala atravesaría el chaleco antibalas.
Explanation:
Un chaleco antibalas soporta el disparo de una bala disipando la energía de esta última a través de su propio material. Si sabemos que el chaleco antibalas soporta 120 joules de energía, cabe saber si la energía cinética traslacional es igual o inferior a ese límite, significando que la bala no atravesaría el chaleco.
La energía cinética traslacional de la bala (
), in joules, queda expresada con la siguiente fórmula:
(1)
Donde:
- Masa de la bala, en kilogramos.
- Rapidez de la bala, en metros por segundo.
Si sabemos que
y
, entonces la energía cinética traslacional de la bala es:
![K = 7472.5\,J](https://tex.z-dn.net/?f=K%20%3D%207472.5%5C%2CJ)
Puesto que la energia cinética traslacional es mucho mayor que la capacidad del chaleco antibalas, la bala atravesaría el chaleco antibalas.
From the calculation, the wavelength of the waves is about 264 nm and belongs to the ultraviolet spectrum.
<h3>What is photoelectric effect?</h3>
The term photoelectric effect can be used to describe the loss of electron from the surface of a metal. Given that; KE = E - W, where;
KE = kinetic energy of the emitted photoelectron
E = energy of the photon
W = work function of the metal
![2= E - 2.71\\E = 2 + 2.71\\E = 4.71ev or 7.5 * 10^-19 J](https://tex.z-dn.net/?f=2%3D%20E%20-%202.71%5C%5CE%20%3D%202%20%2B%202.71%5C%5CE%20%3D%204.71ev%20or%207.5%20%2A%2010%5E-19%20J)

Dispersion
Explanation:
The best word that describes the phenomenon that gives rise to rainbow is dispersion of light.
Dispersion is the process by which white light is separated into different colors or radiation according to their different wavelength.
- In the atmosphere, rainbow is an arc of different colors that forms in the sky.
- Rainbow forms when light is dispersed by water in the atmosphere.
- When rainbow forms light is separated into its different colors and it can be seen in the sky.
