Answer:
20 degrees.
Explanation:
From Snell’s law of refraction:
sinθ1•n1 = sinθ2•n2
where θ1 is the incidence angle, θ2 is the refraction angle, n1 is the refraction index of light in medium1, and n2 is the refraction index for virgin olive oil. The incidence angle of the red light is θ1 = 30 degrees.
The red light is in air as medium1, so n1 (air) = 1.00029
So, to find θ2, the refracted angle:
sinθ1•1.00029 = sinθ2•1.464
sin(30)•1.00029 / 1.464 = sinθ2
0.5•1.00029 / 1.464 = sinθ2
sinθ2 = 0.3416291
θ2 = arcsin(0.3416291)
θ2 = 19.976 degrees
To the nearest degree,
θ2 = 20 degrees.
Answer:
The ion has fewer electrons
Explanation:
As Rubidium forms a positive ion Rb⁺ the number of electrons becomes fewer for the atom.
- A positive charge on an ion indicates that the number of protons for the atom is greater than the number of electrons.
- This leaves a net positive charge on the atom.
- For a negatively charged ion, the number of electrons is more than the number of protons because they have gained additional electrons.
- In a neutral atom, the number of protons and electrons are the same.
Answer:
Reflection is simply the property of a light that rebounds or bounces back after hitting a surface.
Refraction is when the light, which passes through a surface, undergoes some changes in appearance whenever it usually passes through a medium.
Answer:
Explanation:
We shall apply Gauss's Law to find the solution .
flux entering the cube = E X A
= 46.8 X 147.1 X 147.1 Weber
flux going out of cube
= 114 x 147.1 X 147.1 Weber
Net flux going out
= ( 114 x 147.1 X 147.1 - 46.8 X 147.1 X 147.1 )
= 1454101.15 weber .
according to Gauss's law
q / ε₀ = 1.4541 x 10⁶ , q is required charge inside the cube.
q = 8.85 x 10⁻¹² x 1.4541 x 10⁶
= 12.868 x 10⁻⁶ C
= 12.868 μC.
