Answer:
Image result for what does charles law state
The physical principle known as Charles' law states that the volume of a gas equals a constant value multiplied by its temperature as measured on the Kelvin scale (zero Kelvin corresponds to -273.15 degrees Celsius).
Explanation:
Answer:
The height of the pyramid is approximately 104 Ft. See the graphic attached.
Explanation:
First, you have to plot to realize that you have two rectangle triangles, formed by the different elevation points of view. From there you can have a system of two equations, with two unknown values.
Equation (1)
Equation (2)
![tan 18^{o}10'=\frac{Ph}{x+183} \\\\Ph=[tan 18^{o}10'][x+183]=[0.3281][x+183]](https://tex.z-dn.net/?f=tan%2018%5E%7Bo%7D10%27%3D%5Cfrac%7BPh%7D%7Bx%2B183%7D%20%5C%5C%5C%5CPh%3D%5Btan%2018%5E%7Bo%7D10%27%5D%5Bx%2B183%5D%3D%5B0.3281%5D%5Bx%2B183%5D)
Matching (1) and (2)

Answer:
21.5°
Explanation:
Given,
Refractive index of water, n₁ = 1.33
Refractive index of polystyrene, n₂ = 1.49
Angle of reflection = ?
Angle of refraction = 19.1°
Using Snell's law
n₁ sin θ₁ = n₂ sin θ₂
1.33 x sin θ₁ = 1.49 x sin 19.1°
sin θ₁ = 0.366
θ₁ = 21.5°
According to law of reflection angle of incidence is equal to angle of reflection.
Angle of reflection = 21.5°
The electrons stop flowing
