Answer:
D. Inspecting the muffler
Explanation:
HVAC/refigeration systems are sealed systems that use refrigerant not combustion. A muffler is found on combustion systems.
You would disconnect, flush, seal, and possibly replace the condenser if the condenser is found to be failing.
Answer:
The length of the open closed pipe is 12.25 cm
Explanation:
In open - open organ pipe, third harmonic has Antinode to Node, Node to Node, Node to Node and Node to Antinode.
The length of the open-open organ pipe is equal to the sum of wavelength in Antinode to Node, Node to Node, Node to Node and Node to Antinode.
L = A→N + N→N + N→N + N→A
In open-closed pipe, Fundamental frequency has Antinode to Node.
Thus, length of the open-closed organ pipe is equal to the wavelength in Antinode to Node.
L = A→N
From the information in the question, fundamental frequency of open-closed pipe is to the third harmonic of the open-open pipe.
F₀ = F
Therefore, the length of the open closed pipe is 12.25 cm
