Answer:
"The lowest energy configuration for an atom is the one having the maximum number of unpaired electrons allowed by thePauli principle in a particular set of degenerate orbitals" is known as Hund's rule.
Explanation:
Pauli's Exclusion principle states that "two or more electrons can not have the same values of the set of all quantum numbers in an atom or a molecule".
So, the given statement <em>is not</em> Pauli's Exclusion principle.
Hund's rule states that the lowest energy configuration of an atom is that one in which the maximum number of parallel spins of the electrons are present.
The given statement is "The lowest energy configuration for an atom is the one having the maximum number of unpaired electrons allowed by the Pauli principle in a particular set of degenerate orbitals", which is same as the Hund's rule.
Thus, the given statement is Hund' rule.
Heisenberg's uncertainty principle states that the momentum and position of an object can not be measured exactly at the same time.
So, the given statement <em>is not</em> Heisenberg's uncertainty principle.
Aufbau principle tells about the filling of the electrons in subshells of an atom. Therefore, the given statement <em>is not </em>Aufbau principle.
Answer:
Smaller by 7 times
Explanation:
Rotational mass is called moment of inertia
So, initial moment of inertia, I1 = I
initial angular velocity, ω1 = ω
Final moment of inertia, I2 = 7I
Final angular velocity, ω2 = ω/7
The kinetic energy in rotational motion is given by
So, initial kinetic energy of rotation
So, final kinetic energy of rotation
Thus, teh kinetic energy becomes smaller by 7 times.
Answer:
Increasing the number of slits not only makes the diffraction maximum sharper, but also much more intense. If a 1 mm diameter laser beam strikes a 600 line/mm grating, then it covers 600 slits and the resulting line intensity is 90,000 x that of a double slit. Such a multiple-slit is called a diffraction grating.
I believe the correct answer from the choices listed above is option C. <span>If January corresponds to x = 0, the volume of water (in gallons) in the tank be in June would be 75 gallons. </span>
Hope this answers the question. Have a nice day.
