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.
Answer:
H = 1/2 g t^2 no original vertical velocity
t = (2 * 2000 / 9.8)^1/2 = 20.2 s
Sx = 100 m/s * 20.2 s = 2020 m
