In one or two paragraphs, explain why identifying the point of view of a political communication is important. Why should informed citizens consider multiple points of view of the political information they are reading, watching, or sharing?
please help
Political communication is important, because it helps politcal parties and people in genral express how they feel and their opinions. Citizens who consider multiple points of views can see the many opinions of every party. Having multiple views, especially in polotics, can help shape one's opinion. Being a citizen in a country where polotics and news are spread around helps inform and tell the citizen the different views of each party. This is especially important when it comes to voting.

In a Compton scattering experiment, scattered photon is found to have its wavelength three times of the incident photon for the scattering angle of 180°. Calculate Wavelengths (in nm) of the incident, scattered photon, and Compton shift.
Answer:
Two of Einstein’s influential ideas introduced in 1905 were the theory of special relativity and the concept of a light quantum, which we now call a photon. Beyond 1905, Einstein went further to suggest that freely propagating electromagnetic waves consisted of photons that are particles of light in the same sense that electrons or other massive particles are particles of matter. A beam of monochromatic light of wavelength \lambda (or equivalently, of frequency f) can be seen either as a classical wave or as a collection of photons that travel in a vacuum with one speed, c (the speed of light), and all carrying the same energy, {E}_{f}=hf. This idea proved useful for explaining the interactions of light with particles of matter.
prove p = hdg
please give answer if you know
P = Force/Area
= Weight/Area
= Mass × gravitational field strength/Area
= Density × Volume × gravitational field strength/Area
= Density × Area × height × gravitational field strength/Area
P = height × density × gravitational field strength
Hence, P = hdg
The pressure is the force applied on per unit area of an object. It can also be described as the product of height, density, and gravitational field strength.
What is Pressure?Pressure is the force applied perpendicular to the surface area of an object over which that force is applied. Gauge pressure is the pressure that is relative to the ambient pressure on an object. Various units of power are used to express pressure of an object. The SI unit of pressure is Pascal (Pa).
Pressure of an object can be calculated by the formula:
P = Force/Area
P = Weight/Area
P = Mass × gravitational field strength/Area
P = Density × Volume × gravitational field strength/Area
P = Density × Area × height × gravitational field strength/Area
P = height × density × gravitational field strength
Hence, P = h × d × g
Therefore, the pressure of an object can be calculated as the product of height, density, and gravitational field strength.

Answer:
A), C), and E)
Explanation:
Because i'm built different
Options A and C are the noble gases because their outer shell is complete and they do not react with anyone.
What are noble gases?All seven of the chemical elements that make up Group 18 of the periodic table are considered noble gases. Helium, neon, argon, krypton, xenon, radon, and oganesson are the constituent components (Og). Noble gases are inert, tasteless, odorless, and nonflammable gases. Since it was initially thought that these elements could not link to other atoms, that is, that their atoms could not combine with those of other elements to create chemical compounds, they were typically given the Group 0 designation in the periodic table.
The more suitable name, Group 18, has been given to them as a result of their electrical structures and the discovery that some of them do in fact form compounds.

A diver jumps off of the platform and accelerates towards the water at 9.8 m/s2. The diver has a mass of 54 kg. At what force, will the diver jump into the water?
Answer:
The answer is 529.2 N
Explanation:
The Formula for Force is F=M*A
Force equals mass times acceleration,
The mass is 54kg and you multiply that by the acceleration which is 9.8m/s^2
54*9.8= 529.2N
All you have to do is multiply the two numbers when it comes to finding the force.

When the rudder moves to the left the plane will move to the right or left?
To turn the aircraft, the pilot uses all three flight controls. The rudder is controlled in the cockpit by foot pedals. When the pilot presses the left pedal, the rudder deflects to the left. This deflection creates more lifting force on the right-hand side of the rudder, which moves the plane's nose to the left.
Answer:
The rudder will move to the right
Explanation:
This is using opposite forces and aircraft speeds to identify the modules used to make the rudder move the plane. If the rudder moves right, the plane goes left. If the rudder goes left, the plane goes right.

What can you infer about a wave with a long wavelength?
CHOICES:
- It has a high amplitude
- It has a low amplitude
- It has a high frequency
- It has a low frequency
Answer:
It has a high frequency
Explanation:
A wave is the form of sine wave which has crests and troughs. A wave with a long wavelength has a low frequency.
What is the wavelength?Wavelength is the distance between the adjacent crest or trough.
Wavelength is inversely related to the frequency as
f = v / λ
This shows that longer the wavelength, low will be the frequency.
Thus, a wave with long wavelength infers that is has a low frequency.

Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory? A) It was not published until his death. B) It was not understood by scientific world. C) It lacked sufficient evidence and explanation. D) It lacked practical examples in supporting theory.
