Answer:
Explanation:
ASSUMING the 52° is the angle of incidence measured from the perpendicular to the surface
n₁sinθ₁ = n₂sinθ₂
1 sin52 = 1.33sinθ₂
θ₂ = arcsin(sin52 / 1.33)
θ₂ = 36°
as measured from the perpendicular to the surface
Solo dígales cómo se siente, dígales que no está contento porque está triste y no sabe qué hacer al respecto, que está deprimido, y que solo quiere que las cosas mejoren.
Answer:
Number of electrons, n = 6
Explanation:
Total charge in a single droplet, 
The measured charge of any single droplet, 
Let n is the number of excess electrons are contained within the drop. According to the quantization of charge :
n = 6
So, there are 6 electrons contained within the drop. Hence, this is the required solution.
Answer:
William Ferrel created a tide-prediction machine.
Explanation:
- William Ferrel create a machine in late 19th century that was the best combination of mechanical parts and computer coding.
- It was a mechanical analog computer that could predict the ebb of tides and even the height of tides that could be irregular.
- It was widely used for marine networks and navigation. Later on many improvisations and additional features were added on it.
- During the world war times, this tide prediction machine was of great use for military purpose.
