Answer:
[tex]A=186.70\ \text{unit}^2[/tex]
Explanation:
Given that,
[tex]\angle QRS = 74^{\circ}\\\\QR = 17\ \text{units}[/tex]
We need to find the area of sector QRS. The formula for the area of a sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2[/tex]
QR = RS = r = 17 units
So,
[tex]A=\dfrac{74}{360}\times \dfrac{22}{7}\times (17)^2\\\\=186.70\ \text{unit}^2[/tex]
So, the area of sector QRS is [tex]186.70\ \text{unit}^2[/tex]

1)Prime meridian- hottest region
2)equator-green wich
3)torrid zone-poles
4)axis_great circle
Answers
Answer:
Prime meridian - Greenwich
Equator - Great circle
Torrid Zone - Hottest region
Axis - Poles
Explanation:
The Prime Meridian is a line, constructed by humans, which is cutting the world into the Western and Eastern Hemisphere. It passes through Greenwich, UK, which is why it is often referred to just as Greenwich. It is used as a zero zone or central zone for time, with every east given a -, while every zone west is given a +.
The Equator is a human-constructed line that cuts Earth into two equal parts, Northern and Southern Hemisphere. It is the line from which latitude is measured, north and south of it, and it is also the line where Earth is the widest.
Torrid Zone is a climatic generalized zone. It is occupying the tropics, thus including tropical rainforests, dry forests, savannas, steppes, and deserts. This zone can be found on five continents, North America, South America, Africa, Asia, and Australia.
The axis is an imaginary line that runs through the poles. It is a line around which Earth rotates. It is tilted by 23.4 degrees (scientifically referred to as obliquity), which has a great influence on Earth's climate.

How do you know that bipedalism and carnivory are not just Theropod traits?
Answers
Answer:
Just by observation, it can easily be noticed that bipedalism and carnivory are traits of numerous different animal groups, not to mention the fossil remains of the top of it.
Explanation:
Theropoda is a group of dinosaurs that has hollow bones and three-toed feet. They were generally dinosaurs that were bipedal, with the larger specimens have front limbs that have been significantly retracted. Most of the species were also carnivores, and some of the most famous dinosaurs fall into this category, like the T-Rex and Velociraptor.
Bipedalism and carnivory though are not traits unique to the Theropoda only. We just need to look at ourselves and we will find the first clue in us, as humans are bipedal. And it is not just humans, but we also have the kangaroos, wallabies, kangaroo rat, and many more extant and extinct species. When it comes to carnivory, again, we don't have to look far, as the two most popular pets in the world, the cats and the dogs, are carnivores. Some other examples of carnivores are the tiger, wolf, jaguar, cougar, Tasmanian devil, polar bear, leopard seal, and many more.
Which is the first step in the seafloor spreading process? A crack forms in oceanic crust. Volcanoes erupt under the ocean. Molten rock rises up through the crust. Dense plates are subducted under less dense plates.
Answers
A crack forms in oceanic crust is the first step in the seafloor spreading process.
The Red Sea-East Africa Rift System is an example of how seafloor spreading often begins in a continental land mass. The continental crust first becomes more flexible and less solid as a result of heating near the crust's base. The region being heated has the shape of a wide dome because less dense items rise relative to denser objects. Fractures start to form when the crust buckles upward and eventually develop into rifts.
The continental crust will finally attenuate as much as it can while the two active rifts keep spreading. Between the dividing pieces of the continent, basaltic oceanic crust and upper mantle lithosphere start to emerge. The rift system is filled with saltwater and transforms into a new sea when one of the rifts opens onto the surrounding ocean.
Therefore, option A is the correct answer.

What is the gradient of a volcanic cone that has a height of 5340 feet and a base of 4850 feet and the horizontal distance between these two points is 2 miles?
Answers
Answer:
245 feet per mile
Explanation:
The gradient is the same as the slope (that is the rate of change). The gradient of a volcano tells how steep the volcano is. It is the ratio of the change in the height to the change in horizontal distance. The gradient is given by the formula:
Gradient = change in vertical distance or height / change in horizontal distance. Hence:
Gradient = (5340 feet - 4850 feet) / 2 miles
Gradient = 245 feet per mile

Answers
Answer:
Correct answer is:
building an extensive network of roads
granting citizenship to people in outlying areas
Explanation:
First option is correct as throughout the Empire Romans built a large number of roads. The whole Empire was connected with these networks of road.
During the Empire citizenship was granted practically to everyone who lived in the borders of the Empire. Similar culture, religion and language were used across the Empire.
Feudalism was established in the Middle Ages after the fall of Roman Empire, therefore this option is false.
Colonization of North America started at the end of 15th and beginning of 16th Century.
