Answer:
the frequency of this mode of vibration is 138.87 Hz
Explanation:
Given;
length of the copper wire, L = 1 m
mass per unit length of the copper wire, μ = 0.0014 kg/m
tension on the wire, T = 27 N
number of segments, n = 2
The frequency of this mode of vibration is calculated as;
Therefore, the frequency of this mode of vibration is 138.87 Hz

In an atom that has an electron configuration of 1s^2 2s^2 2p^3. The total number of electrons in its sublevel of highest energy is 3.
Electronic configuration represents the number of electrons in the excited state or in the subshells of an element.
1s^2 2s^2 2p^3 is the electronic configuration of nitrogen i.e. N7.
The atomic number of nitrogen is 7 and the atomic mass is 3. Hence, the electrons are in the 's' and 'p' subshells of the main shell.
This electronic configuration shows that nitrogen is in an exciting oxidation state and has 3 electrons in its highest energy level.
