Answer:
Wave speed, frequency and wavelength in refraction
Explanation:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
Wave speed, wavelength in refraction and frequency causes the wavelength of a particular beam of light change.
What is wavelength of a light?The wavelength of light is the separation between both the two crests or troughs of the light wave. It is recognized by the Greek letter lambda (). Therefore, the term "wavelength" refers to the distance between the crest or trough of one wave and the wave that follows it.
The number of waves that travel through a single location in a specific amount of time determines frequency, and the distance between two subsequent troughs or crests determines wavelength. As a result of the inverse connection between wavelength and frequency, frequency falls as wavelength increases.
The wave slows down, but because its wavelength is shorter, its frequency doesn't change. Waves' frequency does not alter as they go from one medium to another. Waves slow down and shorten in wavelength when they move through denser media.

The Old Man of the Mountain was a rock formation on the side of Cannon Mountain in New Hampshire. Scientists believe it formed 200 million years ago when the mountain was covered in glaciers. New Hampshire is known for its harsh, snowy winters. In the 1920s, scientists started noticing large cracks in the face of the mountain. In 2003, the rock formation collapsed.
The picture on the left shows the rock structure before its collapse. The picture on the right shows how the rock structure looks today. (The ghost image shows the part lost in the collapse.)
Answer:
what do you want to know?
Explanation:
Question 1
Part A: The Old Man of the Mountain is a rock formation on the side of a cliff. It was created when glaciers weathered the rock’s surface.
Part B: The cold, harsh winters of New Hampshire weathered the Old Man of the Mountain. This weathering likely led to cracks in its surface from frost wedging. The weight of snow and ice further weakened the structure, causing the rock to loosen and eventually erode.
Part C: The collapse of the Old Man of the Mountain happened quickly in 2003, like a landslide. However, the process was triggered through slow changes to the rock. The wind, ice, and snow from the New Hampshire winters gradually weathered the rock, weakening it and causing the formation to eventually collapse.
Question 2
Part A: 9.3 meters
Part B: 11.9 meters
Part C: The steepness of the line represents the rate of erosion in meters per year.
Part D: y = 1.16x
Part E: Building the Canadian hydroelectric plant reduced the rate of erosion after 1906.
Part F: Hydroelectric dams use the flow of water to create power. The building of the dam decreased the speed and force of water flow over Niagara Falls as the water was diverted to the power plant. The reduced water flow resulted in a lower rate of erosion.

What is one conclusion you can draw about changing political boundaries in africa represented on the maps?
Answer:
The main conclusion that can be determined by observing the map of Africa is that the borders of the nations of modern Africa were determined by the colonial powers that distributed the territories of the continent after the Berlin Conference. Thus, the present borders of the continent do not respect the historical nationalities that the African tribes give each other, with which ethnic conflicts occur in many of these nations, especially in central Africa. Thus, although today it is a practically impossible situation, in case of wanting to respect the historical nationalities of the peoples of the continent, the current national borders should be modified taking into account the ethnic, social and cultural differences of its inhabitants.

Explanation:
The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act, carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates, have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air.How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are:
Riding a bike or walking instead of driving.
Taking a bus or carpooling.
Buying a car that has greater fuel efficiency.
Turning off lights and appliances when they are not in use.
Using energy efficient light bulbs and appliances.
Buying fewer things that are manufactured using fossil fuels.

The sum of angles on a straight line is 180 degrees. The value of t if the angles are supplementary is 24 degrees
Line geometryThe sum of angles on a straight line is 180 degrees. From the given figure, the sum of the angles will be supplementary.
Mathematically;
68 + 5t - 8 = 180
60 + 5t = 180
5t = 180 - 60
5t = 120
t = 120/5
t = 24
Hence the value of t if the angles are supplementary is 24 degrees

List three examples of culture blending in Brazil
Answer:
La cultura de Brasil es eminentemente pluricultural, marcada por grandes y diversas corrientes migratorias provenientes de todos los continentes, sumado al intenso mestizaje. Brasil está conformado por muy diversos pueblos, lo que se refleja en su cultura, que posee elementos principalmente indígenas, africanos y europeos, sobre todo de origen animal.
La cultura popular y la cultura erudita siempre fue bastante problemática en el país. Durante un largo período de la historia, desde el Descubrimiento de Brasil hasta mediados de los siglos XIX y XX, la distancia entre la cultura erudita y la cultura popular era bastante amplia: la primera buscaba ser una copia fiel de los cánones y estilos europeos, la segunda era formada por la adaptación de las culturas de los diferentes pueblos que formaron el pueblo brasileño en un conjunto de valores, estéticas y hábitos rechazados y despreciados por las élites. Gran parte del proyecto estético modernista fue justamente el de rescatar en los campos considerados "nobles" de la cultura (las artes en general, la literatura, la música, etc.) y hasta los hábitos cotidianos, considerándola como una legítima cultura brasileña.
Question
What aspects of Latin American culture have most been influenced by the European colonization of the past?
Answer:
Language and religion are the cultural traits that have been influenced the most by European colonization.
Explanation:
Latin America is a region that spreads from Mexico through Central America and South America. The majority of this region has been colonized by Spain, with Portugal having a big chunk in Brazil and several other colonizers but on a much smaller scale. Having the region under their control, the colonizers managed to have a big influence on the population, and some of the biggest influences can be seen in the language and religion of the region.
In all of the countries of the region, the most spoken language is Europen, mostly Spanish and Portuguese, with all other languages that are presently being used locally or on a much smaller scale. The religion in this region is the same throughout it, with Catholic Christianity being by far the most dominant religion, and it has been brought and forced upon the natives by the Spanish and Portuguese.

Do the land areas around North and South Poles appear smaller or larger in size than they really are?
Answer:
larger
Explanation:
North and South pole almost always look larger on the flat maps than they are in real life when compared to other parts of the world. Antarctica – South Pole – is shown as stretching all across the downside of the map, but it is actually a circular continent, smaller than presented.
This is because from the beginning the main point of flat maps was to navigate, therefore the spaces between the continents needed to be good. Geographer Gerardus Mercator made an accurate navigation map in the 16th century, but the problem was that some elements weren’t well sized so they could be position well against the equator. Poles and their landmasses of Antarctica and Greenland were presented much larger than they are in reality. This phenomenon has a name – Mercator Projection.

What happens when heat from inside Earth is transferred to its surface
Answer:
then is turns into molten rock and creates more land
Explanation:
Answer:
Warmer material is pushed to the crust
Explanation:
Heat from inside the surface is transferred to its surface through conduction. As in conduction, there is transfer of heat from hotter substance to colder substance when placed together.
Therefore, less dense material rises towards the surface by the process of convection and more denser (colder) material remains inside the Earth.
Thus, we can conclude that warmer material is pushed to the crust.
