Answer:
Ionization potential of C⁺⁵ is 489.6 eV.
Wavelength of the transition from n=3 to n=2 is 1.83 x 10⁻⁸ m.
Explanation:
The ionization potential of hydrogen like atoms is given by the relation :
.....(1)
Here <em>E</em> is ionization potential, <em>Z</em> is atomic number and <em>n</em> is the principal quantum number which represents the state of the atom.
In this problem, the ionization potential of Carbon atom is to determine.
So, substitute 6 for <em>Z</em> and 1 for <em>n</em> in the equation (1).
<em> E = </em>489.6 eV
The wavelength (λ) of the photon due to the transition of electrons in Hydrogen like atom is given by the relation :
......(2)
R is Rydberg constant, n₁ and n₂ are the transition states of the atom.
Substitute 6 for Z, 2 for n₁, 3 for n₂ and 1.09 x 10⁷ m⁻¹ for R in equation (2).
= 5.45 x 10⁷
λ = 1.83 x 10⁻⁸ m
I believe the answer is: Nation
Groups of people who live in a nation had to follow a set of regulations that created by their ruling government with clear border that separate one nation with the other.
In the earlier period, these groups might gather with different culture and language. After interacting together for a long period of time, assimilation will occurs and they start to use same language and develop a unique culture that does not exist in other nations.
Answer:
EMF of the power source, E = 19.34 volts
Explanation:
It is given that,
Voltage at which computer sensor is operated, V = 11.7 V
Power, P = 26.37 W
Total resistance of the power source, R = 2.23 Ohms
Firstly, calculating the current in the circuit. It is calculated as :
I = 3.43 A
Let E is the emf of the power source. It is given by,
E = 19.34 volts
Hence, the EMF of the power source is 19.34 volts. Hence, this is the required solution.
Answer:
B
Explanation:
A detailed solution to the problem is shown in the image attached. You could study it. The half life, and percentage of C-14 compared to present living sample was given as 13% of that of a living sample.
Answer:
c). Easier setup
Explanation:
As per the question, <u>'easier setup' cannot be characterized as the advantage of using Access because it comprises of plenty of steps that must be followed in the sequential order to establishing a database or carrying transactions based on time</u>. However, there are plenty of advantages of using Microsoft access like 'enhanced and increased storage of data,' 'hassle free database systems,' 'easy importing of data,' 'highly economical,' 'capability to allow multiple users,' 'extra features for reporting,' and much more. Hence, <u>option c</u> is the correct answer.
