Answer:

[tex] r^\frac{1}{2}[/tex]

Explanation:

Angular momentum, L = m v r

areal velocity = [tex]\frac{dA}{dt}[/tex]

according to kepler's 2nd law

[tex]\frac{dA}{dt}=\frac{L}{2m}[/tex]

since, we know that

[tex]v=\sqrt{\frac{Gm}{r} }[/tex]

areal velocity= [tex]\frac{mvr}{2m} = \frac{vr}{2}[/tex]

now substituting value of v in areal velocity we get

[tex]\frac{1}{2}\sqrt{GMr}[/tex]

hence from above equation of rate of change of area swept i.e. areal velocity is proportional to   [tex] r^\frac{1}{2}[/tex]

Answer:

TRUE

Explanation:

The scientists examine the change in the magnetic field of the earth to determine the age of the ocean floor. Once in a while, the currents in the core of the ocean which create the magnetic field on the earth, are reversed. This is known as a geomagnetic reversal.

When the magnetic data of the sea floor was studied, they discovered about the normal and the reversed magnetic stripes.

The geomagnetic reversals records was matched with the stripes of the normal and the reverse magnetic fields, to determine the age of the ocean floor.

Therefore, the give statement is TRUE.

Answer:

TRUE

Explanation:

    In the early twentieth century several scientists, including Bernard Brunhes in France (in 1906) and Motonari Matuyama in Japan (in the 1920s), discovered that rocks can be divided into two groups: those with normal polarity (ie , where magnetic minerals are oriented according to the Earth's magnetic field): and those with reverse polarity (ie, the alignment of magnetic minerals is contrary to Earth's magnetic field).

    When the magma cools, the ferric elements orient themselves according to the existing magnetic field, "fossilizing" it. Thus, the existence of volcanic rocks with normal polarity and others with inverse polarity, presupposes that, in the geological past, there were periods when the terrestrial magnetic field was inverse from the present one, and others in which it was analogous to the present one, that is, occurred. magnetic field inversions. The geomagnetic reversals records was matched with the stripes of the normal and the reverse magnetic fields, to determine the age of the ocean floor.

Answer: Most countries in Sub-Saharan Africa are in stage 2 of the Demographic Transition, which means that the population is increasing incredibly rapidly, even though the average death age in most countries is still relatively low. This increase in birthrate is due to increased economic activity.

1. c. 100,000 years

There has been multiple glaciations during the geological past of the Earth, but while they have all been separated by millions of years and have appeared randomly, this is not the case in the Pleistocene. The glaciations in the Pleistocene have started to have a cyclic pattern. This pattern is approximately 100,000 years, which is actually the period from the beginning to the peak of the glaciation, thus in general the peak of the Pleistocene glaciations is in about 100,000 years since the beginning of the glaciation.

Q 68. b. Huronian

The Huronian is the first glaciation known to the scientists. It has occurred between 2.4 to 2.1 billion years ago. The reason for the appearance of this glaciation is thought to be the quietness of the volcanoes for millions of years. Because the volcanoes were not erupting, or it was very little, the CO2 levels in the atmosphere dropped, resulting in significant weakening of the greenhouse effect, sot he Earth cooled off, and became a snow/ice ball. This glaciation occurred when there was only unicellular organisms, thus before the explosion of life.r

Q 69. c. Glacial erratics are blocks of rock that are too large for the glacier to move

The glaciers are very powerful, and as they move they manage to move lot of things with them. The things that are moved by the glaciers and later deposited vary from very small sand grains to enormous blocks of rocks. The big blocks of rock that weigh several tons are called glacial erratics. Despite their weight, the glaciers were able to move them over long distance, tens or even hundreds of km away. These rocks are easy to notice, as they stick out in the landscape, having different composition that the native rocks, and looking like they don't belong there.

Q 70. c. About 35 million years ago

Antarctica is a frozen continent in the present, but this has not been the case always. In the past, Antarctica has actually been a continent that was covered with dense forests, having tropical and temperate climate types. This started to change with the breakup of Gondwanaland. As Antarctica was moving away from South America and Africa, it was moving toward the South Pole, and as it was getting closer, the climate started to change. Around 35 million years ago, the first glaciers started to form on Antarctica, and over the next 20 million years, this continent gradually was becoming more and more covered in ice until it got almost completely frozen.

Q 71. d. icy comets

The glaciers on Earth depend on numerous factors in order for them to form and exist. Some of those factors are the precession, eccentricity, and obliquity, all of which have very big impact on Earth's climate, making it warmer and wetter at times, and than making it colder and drier. When the climate is becoming colder and drier, the glaciers start to form, and they start to expand from the poles toward the lower latitudes, as well as occupying the higher mountains around the globe. The icy comets though have nothing to do with the formation of glaciers. While they may have impact with our planet and cause changes, they will be very short lived, and the ice they carry will melt down immediately at the moment of the impact.

Out of the of the following options available, the sun is the largest, measuring at about 432,170 mi.

1. The media outlets often know to misrepresent the fact, which comes out because of two major reasons, the insufficient knowledge of the topic, or trying to get more viewers/readers by pumping up the story. In this case, the media outlets took the lowest temperature, while neglecting the average for the period, thus they used it to say that it was the coldest period in the last decades. Also, by using the title that it was the coldest weather in decades, the people are automatically triggered to read it, thus the media will get more turnout.

2. The statisticians on the other hand, disagreed with the claims of the media outlets. The reason for this was that the media outlets were taking in consideration only a single lowest minimum. That is not the manner in which the lowest temperature in a given period is calculated, but it is the average for of the temperatures for the given period that give a proper picture about the weather conditions.

The media outlets claimed the weather in Baltimore was the coldest in decades, but this was based on a specific event and not the entire pattern of weather data over time. Many statisticians argue that focusing on isolated events can be misleading. It is important to analyze the entire data set and consider long-term trends and patterns.

The media outlets claim that the weather in Baltimore between January 6 and 8, 2014, was the 'coldest weather in decades' because they were focusing on a specific event rather than looking at the entire pattern of weather data over time. While it may have been the coldest weather in Baltimore in recent years, there was a period in 2009, January 15 to 17, that had even colder temperatures. Many statisticians argue that looking at isolated events or specific records can be misleading when trying to understand the typical weather patterns. Instead, it is important to analyze the entire data set and consider long-term trends and patterns.

Explanation:

The desertification is a process that has become a very big concern in numerous places around the world. With the climate becoming warmer, and with the destruction of the vegetation, this process has become a major environmental concern. Some places though do not have any problem with desertification, like Japan and the Korean Peninsula. In fact, it would be pretty hard to make these two places deserts even if the humans wanted too, and the main reason is that they are under heavy influence of the sea, so they get solid amounts of rainfall and snowfall throughout the year.

a. Its consideration of environment impact (such as accommodation for fish) became a model for future dam projects on western rivers

Explanation:

The Columbia River project was a project of great significance for the whole region, especially for the state of Washington. This project had many positive impacts such as production of electricity, irrigation for more than half of the farmlands, development of the area, opening up new jobs. One very big problem though was the impact on the species of fish in the river. As most of them are migratory species, with the building of the dam they were stopped in their movement, thus they became restricted to the upper part of the river. Also, the water and composition of the water changed, and all of these things contributed to significant reduction of the populations of the native species of fish.

Answer:

volcanic island arcs caused by ocean-ocean convergent boundaries.

Explanation:

The geological features that are found in the continent-ocean convergent plate boundary are the deep sea trenches and continental volcanic arc .

Continental volcanic arc is that arc shaped volcanic mountain chain formed due to the subduction of oceanic plate within the continental plate.

While Volcanic island arc are formed when both the plates are oceanic and one subducts inside the other. The arc shape of the mountain chains is formed due the spherical shape of the earth.  

Volcanic Island arc caused by ocean-ocean convergent boundaries. In this convergence, the denser oceanic plate get subducts below the less denser oceanic plate forming a trench along the boundary .

Answer:

Minerals Available in Rock

Texture

Color

Chemical composition

Explanation:

There are different criteria that could be used to classify rocks that are igneous. These are:

1) Minerals Available in Rock: The minerals in a rock and their relative proportions in the rock mainly rely on the magma's chemical composition.

2) The Rock's texture: Rock texture largely relies on the magma's cooling history. Thus rocks with the same chemical composition and presence of the same minerals could have very distinct textures.

3) Color: A rock's color relies on the minerals and the size of the grain. Generally speaking, rocks containing lots of feldspar and quartz are light colored, and rocks containing lots of pyroxenes, olivines and amphiboles (minerals of ferromagnesium) are dark colored. But when applied to rocks of the same structure but distinct grain size, color can be misleading.

4) Chemical composition: The most distinctive characteristic is the chemical composition of igneous rocks. The structure generally represents the magma's structure, thus providing data about the rock's source.

Answer:

d) nationalism/race or ethnicity

Explanation:

World War One was primarily about, nationalism , while World War two largely concerned race or ethnicity.

Explanation:  John Locke (1632-1704), was an English philosopher and political theorist. He is considered to be the founder of the British Empiricism, and his idea of ​​overseeing and controlling the liberal government by the citizens they have chosen is also known. Locke's empiricism is the theory by which every knowledge is the result of experience, so that when someone is born his knowledge is a blank board as Locke argued. So there is no innate knowledge, every knowledge is acquired by experience, and experience is sensation and reflection. The human mind gathers information based on experience, and it creates ideas that then compares, analyzes and combines. Thus combined ideas create a certain kind of relationship between them in the human mind, which is knowledge.

Final answer:

John Locke is an empiricist because he believes that all knowledge comes from sensory experience. According to Locke, our ideas originate from the experiences we gather through sensation and reflection, and we are born with minds like a blank slate, or tabula rasa, without any innate knowledge. This perspective counteracts the notion of inherent ideas or concepts being present at birth, positing that our understanding and ideas develop as we interact with the world.

Explanation:

Locke's empiricism is detailed in his work, An Essay Concerning Human Understanding, where he describes the mind at birth as a tabula rasa. This blank slate is then shaped by experiences obtained through the senses—sight, sound, taste, touch, and smell—and through reflection upon these sensory inputs, we form simple ideas that evolve into complex ideas. Locke's innovative view was fundamentally opposed to the prevailing notion of innate knowledge existing from birth. Instead, Locke posited that knowledge and ideas are the outcomes of empirical evidence and logical reasoning, underpinning the modern scientific method and influencing subsequent philosophical inquiry.

Answer:

Yes, the other lamps will be affected.

Explanation:

Since lamp is connected in series circuit and in series the same current flows throughout the supply and the current is not divide and flows through a particular path.

So, if the supply across any one  circuit element is interrupted then this result in the interruption of supply to the whole circuit. In series current is same throughout but the voltage or potential difference across each circuit element varies as the resistance or reactance of that element varies and remain independent of the current.

Thus if one lamp in series burns out, all other lamps will also be disconnected due to the discontinuity of the current as the circuit is interrupted as a result of burn out.

Answer:

D. river current exceeds the oceanic current

Explanation:

The bird's foot delta type of deltas occur at places where the river current exceeds the oceanic current. This is the case with the Mississippi River and its delta. The current of the Mississippi River exceeds the currents from the Gulf of Mexico which are very weak. Because the currents of the Gulf of Mexico are very weak, the river is depositing lot of sediments at its final part. The accumulation of this sediment results in splitting up of the river in a triangular manner at its delta, giving it an appearance of the bird's foot, thus the name bird's foot delta.

A "bird's foot" delta configuration develops when the river current surpasses the oceanic current (option D). This is caused by the river's high silt content discharging into oceans with minimal currents and wave action, resulting in delta formations.

A "bird's foot" delta configuration, such as the one displayed by the Mississippi River delta, forms when the river current exceeds the oceanic current, option D. This happens because as a river reaches the ocean or a large lake, the water typically slows dramatically causing any silt in the river water to settle. Rivers with high silt content that discharge into oceans with minimal currents and wave action can build deltas. Deltas are low-elevation areas of sand and mud, formed as the silt settles onto the ocean bottom. Conversely, rivers with low silt content or in areas where ocean currents or wave action is high create estuarine areas, where fresh and salt water mix.

According to Orientalism -

1. The academic study of the orient , teaching and writing about them .

2. The way of thinking based on the ontological and epistemological distinction between the Western and eastern countries . orientals and Occidentals differ greatly and only westerns can produce knowledge of the orient.

3. A way of defining and commanding the orient . Western states dominates the orients on matter of intellect and economics.

Orientalism does not distinguish between different peoples in the east . This leads to a static view of the orient - opposite to the progress in the west.

Hence ,

Correct option is ( c ) both a and b.

During the Enlightenment, European thinkers used the Orient as both a critique of their own societies and as a means to demonstrate their superiority, a dual approach embodied by the concept of Orientalism.

During the Enlightenment, Western European thinkers utilized the concept of the Orient as both a means of critiquing their own society and a means of demonstrating the superiority of their society. This process is encapsulated by the term Orientalism, a concept put forth by literary critic Edward Said. Said argues that orientalism portrayed non-European societies, particularly those in Asia and the Middle East, in a way that emphasized their perceived irrationality and mystique. This served not only as a juxtaposition to the rational, moral, and democratic ideals in European societies, but also provided a critical mirror through which Europeans could reflect on their own societal practices and philosophies.

Enlightenment thinkers were diverse in their ideas, but they collectively emphasized the use of reason and the scientific method to understand the world. They also grappled with concepts of natural rights and social contract theory, which influenced Western legal and political structures. However, the depiction of the Orient by European thinkers was often done in a manner that reinforced European ethnocentrism while simultaneously using the Orient as a critical lens for European societal flaws.
