Answer:
It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy.
Explanation:
The photovoltaic solar panels transfer the heat energy into electrical energy. This means that the sunlight energy gets converted into electricity.
Photovoltaic cells needed an electric field to function. A magnetic field is created when contrary poles are separated, and an electric field is created when opposite charges are detached.
They do this by seeding phosphorous into the top layer of silicon, which adds extra negative-charged electrons to that layer. Meanwhile, boron is added to the bottom layer, resulting in fewer electrons and a positive charge.
All of this adds up to an electric field at the silicon layer's junction.
Therefore, the correct option is A.

Locate the state boundary between Nebraska and Iowa along the Missouri River. Why does the boundary depart from the river channel
Answer:
The original boundary between the states of Nebraska and Iowa was the Missouri River. The border departs from the river channel because the river's course moved eastward many years after the boundaries were established.
Explanation:
The boundary between Nebraska and Iowa was the Missouri River. In 1877, the river course moved, and a town called Carter Lake on the Iowa side is now on the Alaska side. Even though Alaska claimed the land, the Supreme Court stated that the area belongs to the state of Iowa. That is why the boundary departs from the river channel.

Answer:
D.
Outdoor shopping spaces located in pedestrian zones have been developed to cater to shoppers walking or biking.
Explanation:
GOT IT CORRECT ON TEST!!!!!
The work summarized in this volume focuses on suburban retail environments, particularly the suburban shopping mall, and the changes they bring about in urban organisms. Hence option D is correct .
What is suburban environment ?The growth of the modern metropolis depends greatly on the subject. Additionally, the growth of e-commerce pushes these structures to undergo spatial and functional changes, which results in a new interaction with the city.
The conceptual and methodological tools of urban morphology, notably those of the typological processual approach, are used to carry out the analytical reading, which is supported by generative and design projections.
Due to the fact that these locations are surrounded by residential areas and are therefore located on the outskirts of a city, the suburban environment requires specialized shopping centers. Unlike the rural or urban areas, theyboth have stores, however the urban stores have a greater variety of items for the community while the suburban stores stock only what is absolutely necessary.

BD is the angle bisector of ZABC
5x-Y
2x+y
14+y
(x+13y
x=[ ? ]
Enter
Answer:
x = 7, y = 2
Explanation:
Two triangles are said to be congruent if all three sides and three angles of one triangle is equal to three sides and three angles of the other triangle.
From the question:
BD ≅ BD (reflexive property of equality)
Since BD is the angle bisector of ∠ABC, hence ∠ABD = ∠CBD
∠ABD = 2x + y, ∠CBD = 14 + y. Therefore:
2x + y = 14 + y
2x = 14 + y - y
2x = 14
x = 14 / 2
x = 7
Also, ∠BAD = ∠BCD = 90° (right angled triangle)
Since ∠BAD = ∠BCD, BD ≅ BD and ∠ABD = ∠CBD, therefore ΔABD is congruent to ΔCBD by angle-angle-side congruence theorem.
The angle-angle-side congruence theorem states that if two angles and one side of one triangle is equal to two angles and one side of another triangle the both triangles are congruent.
ΔABD is congruent to ΔCBD, therefore AD = CD
5x - y = x + 13y
13y + y = 5x - x
14y = 4x
14y = 4(7)
y = 4(7) / 14
y = 2
Thunderstorms develop as a result of which process in ocean areas?
Answer:
Explanation:
To form, these storms require three basic ingredients: Moisture, unstable air and lift. Moisture in the air typically comes from the oceans—and areas near warm ocean currents evaporate lots of moisture into the air. Moisture in the air is also responsible for making clouds.
Thunderstorms develop as a result of intense, rotation updrafts are Supercells process in ocean areas.
What do you mean by the thunderstorms?Thunderstorms are ferocious, brief meteorological disturbances that are nearly always accompanied by lightning, thunder, thick clouds, significant amounts of rain or hail, and strong gusts of wind.
Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form.
Lightning that strikes the air produces thunder. The air is immediately heated and expanded by the lightning discharge.
Five times hotter than the sun's surface, the air in the lightning channel can get as hot as 50,000 degrees Fahrenheit.
Therefore, Thunderstorms develop as a result of intense, rotation updrafts are Supercells process in ocean areas.

6. One sample has a chemical composition with a ratio of two iron atoms to three oxygen atoms. Another sample has a chemical composition with a ratio of three iron atoms to four oxygen atoms. They contain the same elements: Are they the same mineral?
Answer: They are not.
Explanation:
When it comes to molecular bonding, a single additional atom can change the characteristics of the compound. This is why Carbon Dioxide is different from Carbon Monoxide even though they both contain only Carbon and Oxygen atoms albeit in different quantities.
In this scenario the compounds described are Hematite which has two iron atoms to three oxygen atoms and Magnetite which has three iron atoms to four oxygen atoms. The presence of the different number of the same atoms made these compounds different.

Do Arabs support the Zionist movement? Why or Why not?
Answer:
No
Explanation:
"In the Beginning There Was the No." The pro-Israel camp often traces the history of the conflict to 1947, when the Arabs said No to the UN partition plan, or to 1948, when the Arab countries said No by launching a war against the recently declared Jewish state. The underlying assumption is that the Arabs had no good reason to reject Zionism or the idea of Jewish self-determination in Palestine: rather, their rejection is interpreted as a consequence of their inherent anti-Semitism, natural tendency toward violence, or self-destructive intransigence.

-Define a local map.
Answer:The National Map is a collaborative effort of the United States Geological Survey and other federal, state, and local agencies to improve and deliver topographic information for the United States.
A local map is a transform that provides a hierarchical view of element transforms in a message map. You can use local maps to break up a large map into nested groups of mapping elements and process the complex elements of the whole data object. Local maps are a partial view of a larger map, rather than separate files.

(iii) In addition to direct measurements, relative sea surface temperatures can be inferred with radar measurements from satellites. Cold sea surface water will be further away from the satellite than warm sea surface water. Explain why this occurs.
Answer:
The reason cold sea surface water will be further away from the satellite than warm sea surface water is because the satellites are placed a relatively fixed height. The waters levels however are not.
Explanation:
Whenever the climate heats up, sea water level rises because:
first, the sea water expands as it is heated up;second, as the climate and the sea gets warmers, the icecaps melt. Both action give an upward spiral to the water level.So, because the satellites are fixed but the water level is rising, the distance between the satellites and the warm sea surface water is reduced.
In contrast, as the climate gets cooler, water contracts and freezes up and cause the water level to shrink thus causing the satellite to be 'farther away' from the surface of the water.
