Answer:
wavelength of the second photon emitted is 97.26 nm
Explanation:
Data provided;
Wavelength absorbed = 94.98 nm
Wavelength of the one of the emitted photon = 4052.3 nm
Now,
The energy is given as:
Energy = 
here,
h is the plank's constant
c is the speed of the light
λ is the wavelength
Now,
by the principle of conservation of energy
Initial energy = Final energy
Therefore,
= 
+ 
or
= -
or
= 
- 
or
= 0.0105 - 2.46 × 10⁻⁴
or
= 0.01028
or
λ₁ = 97.26 nm
Hence,
the wavelength of the second photon emitted is 97.26 nm
Answer:
The correct answer is letter "A": Sender encodes message.
Explanation:
Communication is the process of transmitting information from one party to another. The communication process has five (5) steps: <em>encoding, planning, medium, decoding, </em>and <em>feedback</em>. In the encoding step, the idea to be transmitted is schemed in letters, words or symbols without sending them to the channel.
Thus, <em>by writing a recommendation report, Crystal Jenkins is in the encoding stage of communication.</em>
Answer:
The criticism is true to a certain degree, and unjustified to another degree.
Explanation:
It is true in the sense that the U.S. has indeed lost a lot of manufacturing to Mexico, simply because Mexico has far lower labor costs, and U.S. manufacturers have decided to take advantage of that by taking their plants to Mexican states.
It is also true that Mexico has been running a trade surplus with the United States in recent years, mainly because of the large manufacturing sector that Mexico has been developing.
On the other hand, the criticism is unjustified because neither a trade deficit nor the moving of manufacturing to Mexico mean that the United States as a whole is in worst condition than before NAFTA. In fact, most economists agree that free trade is a good thing for the economy as a whole, and that most people benefit from the lower costs and specialization that trade brings about.
The problem lies then, in the people who lose their jobs: formerly unionized manufacturing workers from the Rust Belt, for example. These people need to be helped with government assitance, both in terms of welfare, and training, so that they can find new jobs and make ends meet in the meanwhile.
Answer:
The formula for average is =AVERAGE(E15,E16).
The formula for highest is =MAX(F15,F16).
The formula for lowest is =MIN(G15,G16).
Explanation:
In MS Excel, on the left hand side below the tool bar there is a small box which tells the cell name where the cursor is clicked, the name of the cell can be changed from here easily, click on the desired cell and then by clicking on the box you can enter the name of the cell. After a cell is renamed the formula can be written by simply putting the name of the cell instead of the original e.g. E13
The formula for average is =AVERAGE(E15,E16).
The formula for highest is =MAX(F15,F16).
The formula for lowest is =MIN(G15,G16).
The cells provided in the formula above is just an example and more than two cells can be selected.
