In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media. Mathematically, this is:
n₁sin(∅₁) = n₂sin(∅₂)
Where n is the refractive index. Substituting the values given into the equation:
1.0003 * sin(20°) = 1.33 * sin(∅)
∅ = 14.91

The angle of the refracted ray is 15°.

How does a swimmers form affect the kinetic and potential energy’s?
oee [108]

When a swimmer is submerged into the water, the Gravitation energy is transformed into Kinetic Energy instead. Consequently, this also means that when the diver/swimmer chooses to get out of the water and becomes free from the water again, Potential Energy is restored. This is because it allows the swimmer to do further tasks.

a water balloon is thrown a target at 18 m/s. if the water balloon has a mass of 0.4 kg, what is the momentum?
Arada [10]

The momentum of the water balloon at the given speed is 7.2 kgm/s.

The given parameters:

  • <em>Speed of the water balloon, v = 18 m/s</em>
  • <em>Mass of the balloon, m = 0.4 kg</em>

The momentum of the water balloon is calculated as follows;

P = mv

<em>Substitute the given values of </em><em>mass </em><em>and </em><em>velocity </em><em>as follows;</em>

P = 0.4 x 18

P = 7.2 kg m/s.

Thus, the momentum of the water balloon at the given speed is 7.2 kgm/s.

Descreva sucintamente como ocorre a formação do raio x pela ampola ou tubo
Umnica [9.8K]

Um tubo de raios-X é um tubo de vácuo que converte a energia elétrica em raios-X. A disponibilidade dessa fonte controlável de raios-X criou o campo da radiografia, a imagem de objetos parcialmente opacos com radiação penetrante. Em contraste com outras fontes de radiação ionizante, os raios X são produzidos apenas enquanto o tubo de raios X estiver energizado. Os tubos de raios-X também são utilizados em scanners de tomografia computadorizada, scanners de bagagem de aeroportos, cristalografia de raios-X, análise de materiais e estrutura e para inspeção industrial.
