I hope this helps!
To solve this problem we will apply the concepts related to the wavelength of its third harmonic.
It describes that the wavelength is equivalent to

Here,

The wavelength is in turn described as a function that depends on the change of the speed as a function of the frequency, that is to say

In this case the speed is equivalent to the speed of sound and the frequency was previously given, therefore


Finally the length of the pipe would be


Atomic Number would be what you are looking for
Answer:
Option B
Wire each room in parallel with the next.
Explanation:
By having parallel circuit, it creates more than one path for energy source. That means that even if one route has been closed by one neighbour, the energy source can get another path. One advantage of parallel connection is that even if one load goes out, the rest of the bulbs within the circuit are not affected. For parallel circuit, voltage remains constant every time a new load is added or removed since each load has its own path to the energy source and will receive full voltage. Therefore, the electrician should wire each room in parallel with the next.
