Answer: An expansion valve.

Explanation:
The expansion valve is a copper tubing that contains a small orifice. The orifice restricts the flow of the refrigerant and makes it undergo a severe drop in pressure and temperature when it exits the orifice.
The temperature drop provides the cooling required in the cooling coils of the refrigerator.

Sabiendo que el indice de refracción dela gua es 1,33 calcula el ángulo de refracción resultante para un rayo de luz que incide

Kaylis [27]

Answer:

35.16 degrees

Explanation:

Knowing that the index of refraction of the guide is 1.33, calculate the resulting angle of refraction for a ray of light that falls on a pool with an angle of incidence of 50º

Refractive index, n = 1.33

The angle of incidence, i = 50°

We need to find the angle of refraction. let it is r. It can be calculated using Snells law as follows:

$n=\dfrac{\sin i}{\sin r}\\\\\sin r=\dfrac{\sin i}{n}\\\\r=\sin^{-1}(\dfrac{\sin i}{n})\\\\r=\sin^{-1}(\dfrac{\sin 50}{1.33})\\\\r=35.16^{\circ}$

So, the angle of refraction is 35.16 degrees.
