If the measure of a tangent chord angle is 68 degrees then what is the measure of the intercepted arc inside the angle
Answers
Answer:
136°
Explanation:
Theorem: The measure of the angle formed by a tangent and a chord is equal to one-half the measure of the intercepted arc.
In the diagram below, PR is the chord, PRS is the tangent, and PQR is the intercepted arc.
Per the theorem,
mPRS = ½mPQR
mPQR = 2mPRS = 2 × 68° = 136°
The measure of the intersected arc is 136°.
Theorem: The measure of the angle formed by a tangent and a chord is equal to half the measure of the intercepted arc.
The diagram below shows the chord PR, the tangent PRS, and the intercepted arc PQR.
This is theorized,
12mPQR = mPRS
mPQR=2mPRS=2 68°=136°
The intersecting arc has a 136° length.
What are the 5 theorems?Thales of Miletus, who lived and worked around 600 BC, is credited with some of the earliest geometric arguments that are still in use today.
In specifically, he is credited with proving the following five theorems: Any angle scribed in a circle is divided by any diameter, any angle scribed in a semicircle is a straight angle (90°), and opposite Two triangles must be congruent (of the same shape and size), the "vertical"angles created by the intersection of two lines must be equal, and isosceles triangles must have equal base angles.
The English mathematician Thomas Heath (1861–1940) presented what is now known as Thales' rectangle (see the picture) as a demonstration of (5) that would have been consistent with what was known in Thales' era, despite the fact that none of Thales' original proofs have survived.

El Niño events are characterized by: warm water piling up near Indonesia. a very strong cold current flowing along the eastern edge of South America. strengthening of the NE trade winds. pooling of unusually warm water in the eastern tropical Pacific.
Answers
The correct answer is D. Pooling of unusually warm water in the eastern tropical Pacific.
Explanation
The Niño phenomenon is a climatic event that is related to the warming of the equatorial eastern Pacific Ocean. This phenomenon usually has great effects in the continental zone of equatorial America, because it produces abundant rains and in some areas it causes the fish to move. The irruption of these warm waters is due to the atmospheric difference between the eastern or western Pacific Ocean. So, the correct answer is D. Pooling of unusually warm water in the eastern tropical Pacific.
El Niño events are characterized by unusual warming and pooling of water in the eastern tropical Pacific. This results from weakening of usually westward-blowing winds, allowing the warm water to flow back eastward. El Niño's effect ripples globally, influencing weather patterns and causing extreme conditions like droughts or floods.
Explanation:El Niño events are characterized by a pooling of unusually warm water in the eastern tropical Pacific. Unlike normal conditions, during El Niño, the prevailing winds which usually blow to the west weaken. As a result, warm water that had been piling up near Indonesia due to these winds is allowed to flow back towards the east.
El Niño does not involve a very strong cold current flowing along the eastern edge of South America. In fact, it is associated with warmer than usual sea surface temperatures in the eastern Pacific. The strengthening of the NE trade winds is also a condition for La Niña, the counterpart of El Niño, not El Niño.
It's important to note the effects of El Niño can be felt globally. It can influence global weather patterns and lead to devastating droughts or flooding in different parts of the world.

Metamorphic rocks formed during episodes of mountain building typically show textural characteristics indicative of shearing stress and deformation. True or false?
Answers
Answer:
True
Explanation:
Metamorphic rocks are changed rocks. These are rock types that have been subjected to intense pressure and temperature to have effected mineralogical changes in a pre-existing.
During mountain building processes usually at plate margins, rocks are subjected to a very high level of tectonic stress and elevated temperature resulting from frictional heating between rocks.
Stress is the force applied per unit area. In a rock body, it causes deformation. The evidence of the deformation is recorded as fabrics in metamorphic rocks. An ideal environment for shearing stress and deformation to take place is where orogenic forces(mountain building) are at work.
Final answer:
True. Metamorphic rocks formed during episodes of mountain building often display textural characteristics that are indicative of shearing stress and deformation. Such metamorphic rocks typically show foliated textures as a result of the directed pressures and high-temperature conditions they undergo.
Explanation:
Metamorphic rocks are transformed from pre-existing rocks under the influence of high temperature, pressure, or chemically reactive fluids. Characteristics like foliation occur due to directed pressure which aligns minerals perpendicularly to the main stress, resulting in a layered or banded appearance. This kind of metamorphism is common beneath mountain ranges where geological processes lead to increased pressures and temperatures as rocks are pushed to greater depths by the thickening of the Earth's crust during plate tectonics activity. Over time, rocks can be uplifted and exposed by erosion, revealing the foliated patterns. Understanding the formation of these metamorphic rocks is complex, as they may undergo multiple tectonic events leading to varied properties. Geologists classify these rocks based on the texture, mineral content, and the temperature and pressure conditions they endured during metamorphism.

What is the difference between a fracture zone and transform fault? A transform fault is a crack, but a fracture zone is a hole in the crust A transform fault is perpendicular to the mid-ocean ridge, but a fracture zone is not. They are two names for the same feature, a break in the plate formed by a slip at a transform plate boundary A transform fault has strike-slip motion in reverse of the direction that the plates move apart at the mid-ocean ridge, but a fracture zone has the opposite sense of motion. A transform has an active fault, separating two plates, whereas a fracture zone is just the “scar” formed on one plate by the transform fault
Answers
Answer:
A "transform fault" is a fault line where two tectonic plates slide against each-other. Not all faults are transform faults. Some plates separate and allow magma to seep up and like a scab, creating new ground (these are called divergent faults.) Other faults, such as convergentfaults, occur when two plates smush into each-other and one is forced below the other where it heats up and is eventually destroyed. And the fracture zone is thus the junction between oceanic crustal regions of different ages.
Explanation:
Answer:
The difference between a racture zone and transform fault Is: transform has an active fault, separating two plates, whereas a fracture zone is just the “scar” formed on one plate by the transform fault
Explanation:
All right to understand this answer we need to remember what is a fracture zone and a transform fault.
All right, first of all, Fracture zones are oceanic linear structures that are produced by platonic plaques movement. So when they move and provoke a terrain change they can be created. They can be tectonic active and preserve a crest in the edges.
Transform faults are terrain boundaries of tectonic plaques with horizontal motion, they are also connected to another transform fault and in many cases, they picture zig-zag scenarios in the bottom of the ocean.

Answers
Final answer:
Paleomagnetism studies the magnetic properties in rocks to understand Earth's past magnetic field directions and intensities, which help in determining the depositional age of sediments.
Explanation:
Paleomagnetism is the study of the recorded magnetism in rocks. When magma cools, the magnetic iron-bearing minerals align themselves with the Earth's magnetic field and record direction and intensity. Geologists can analyze the magnetic properties of sediment cores for magnetostratigraphy, which is used to help determine the age of sediment deposition. This is possible because magnetic minerals in igneous rocks crystallize in alignment with Earth's magnetic field, and even sediments can align themselves as they are deposited. Therefore, the paleomagnetic properties in these sediments can be compared to known changes in Earth's magnetic field and then used to determine the sediment's depositional age.

Answers
Answer:
Planetary orbits are almost circular, with low eccentricities.
Explanation:
Planetary motion is explained by Kepler's three laws. According to the Kepler's three laws of planetary motion, the orbits of planets are elliptical with Sun at one of its focus. These paths have low eccentricities which makes them almost circular.
The orbits are neither equally spaced nor closely together as they get further. The planetary orbits are almost along the ecliptic. (Ecliptic is the path of the Sun as observed from the Earth throughout the year).

In the urban parts of Africa more and more people are getting engaged in multiple jobs. This trend is because of several reasons.
There is an increase in the number of poor people or people living close to poverty lines. To meet their ends, they are doing multiple jobs.
Also, there is limited job job creation in the private sector. Economic growth is slow leading to lesser job creation than required.
In the public sector as well, there is no job creation, in fact retrenchment is taking place.
Though multiple jobs do not have link with government programs to reduce population.

Explanation:
The boreal forest is a biome that is found in the Northern Hemisphere. It is located between the temperate forests and the tundra. These forests are dominated by coniferous trees. The climate is continental, with the winters being very cold and snowy, while the summers are pleasant with mild temperatures. The animals that live in these forests are the elk, moose, deer, wolverines, wolves, black bears, mink, foxes, lynx, among others. All these animals have special adaptations that enable them to live in this biome. They all have thick fur for most of the year, only shedding slightly during the summer.Their paws tend to winder and have goo isolation so that they can walk easily on the snow and avoid frostbite. It is not a biome that has very big diversity in flora and fauna, but it is not a one that lacks in it as well.
Final answer:
The animals like deer, moose, elk, black bear, mink, wolves, and wolverines are typically found in the taiga and boreal forests. This biome is characterized by cold climates, coniferous forests, and animals adapted to endure long winters with behaviors like hibernation and migration.
Explanation:
The animals listed such as deer, moose, elk, black bear, mink, wolves, and wolverines are best associated with the taiga and boreal forests.
In North America, the taiga or boreal forest is a biome characterized by coniferous forests consisting mainly of pines, spruces and larches. Here, you can typically find animals adapted to colder climates. For example, the moose is a defining animal of this biome, so much so that it has contributed to the nickname "spruce-moose biome."
These animals have evolved to endure the long, snowy winters common in the boreal forest. Many of them, such as black bears, hibernate during the winter, while others, like birds, migrate to warmer areas. The biodiversity in the taiga is less than that found in tropical rainforests, but it still hosts a considerable number of species, reflecting the ecosystem's productivity during the growing season.
