Answer:
Closely fits into the connector.
Explanation:
It's one of the steps used for the splicing of aluminium conductors in the underground connections. Where we do the strip insulation to splice the conductors by using compression type connectors.
careful observation, curiosity, logic, creativity, skepticism, and objectivity
Length of the pipe = 0.39 m
Third harmonic frequency = 1400 Hz
For the third harmonic:
Wavelength =
The center of the open pipe will host a node and the nearest anti - node from the center will be at the 0.25 × wavelength
Distance from center = 0.25 × wavelength
Distance =
Plugging the value of the length of the pipe (L) = 0.39 m = 39 cm
Distance =
Distance from the center to the nearest anti - node = 6.5 cm
Hence, the nearest distance to the anti - node from the center = 6.5 cm
So, option C is correct.
I think these two variables are sufficient to completely specify the state.
In an isolated room with air only ,the volume is fixed.Mass ,density and its specific volume can be easily known.
Other thermodynamic properties like entropy, enthalpy etc are also fixed at a given temperature & pressure.
