A Dangerous Ride. You and your exploration team are stuck on a steep slope in the Andes Mountains in Argentina. A dead y winter storm is approaching and you must get down the mountain before the storm hits. Your path leads you around an extremely slippery. horizontal curve with a diameter of 88.0 m and banked at an angle of 40.0
∘
relative to the horizontal. Youget the idea to unpack the toboggan that you bave been using to haul supplies, load your team upon it, and ride it down the mountain to get enough speed to get around the banked curve. You must be extremely careful, however, not to slide down the bank: at the bottom of the curve is a steep cliff. (a) Neglecting friction and air resistance, what must be the speed of your toboggan in order to get around the curve without sliding up or down its bank? Express your answer in m/s and m. ph. (b) You will need to climb up the mountain and ride the toboggan down in order to attain the speed you need to safely navigate the curve (from part (a)). The mountain slope leading into the curve is at an angle of 30.0
∘
relative to the horizontal, and the coefficient of kinetic friction between the toboggan and the surface of the slope is (μ
mountain
=0.17). How far up the mountain (distance along the slope, not elevation) from the curve should you start your ride? Note: the path down the mountain levels off at the bottom so that the toboggan enters the curve moving in the horizontal plane (i.e, in the same plane as the curve). (a) Number Units m/5 Number: Units m.ph. (b) Number Units
Given data:The diameter of the curve = 88.0 m
The angle of the curve = 40 degrees = 40°The coefficient of kinetic friction between the toboggan and the surface of the slope = 0.17
(a)To find:The speed of the toboggan in order to get around the curve without sliding up or down its bankConcepts used:Banked curveLet, v be the speed of the toboggan and R be the radius of the curve.As the banked curve is frictionless,The centripetal force required to overcome the gravitational force is provided by the normal force acting on the toboggan. Therefore,N = m * v² / RR = D / 2 = 88.0 / 2 = 44.0 mN = m * g = m * 9.8 m/s²∴ m * v² / R = m * g∴ v² / R = g∴ v = √(gR) = √(9.8 × 44.0) = 19.6 m/s
Therefore, the speed of the toboggan is 19.6 m/s. (b)To find:The distance along the slope from where you should start your ride.Concepts used:Work-energy theorem Let, h be the height at which the toboggan is started from rest, L be the distance along the slope to the start of the curve, and M be the mass of the toboggan and its team.The potential energy at the height h is M * g * h.The initial kinetic energy is zero. The final kinetic energy is M * v² / 2.The work done by the force of kinetic friction is -μ * M * g * L. (negative sign as the force of friction is opposite to the direction of motion)
By conservation of energy,M * g * h = M * v² / 2 - μ * M * g * L∴ L = (M * v² / (2 * μ * M * g)) + h∴ L = v² / (2 * μ * g) + hLet's substitute the given values,v = 19.6 m/sμ = 0.17g = 9.8 m/s²h = L * sin(30°) = L / 2L = (19.6² / (2 * 0.17 * 9.8)) + (L / 2 * 2)∴ L = 483.3 mTherefore, the distance along the slope from where you should start your ride is 483.3 m.

The development of a glacial period requires:
cool summers so that snow doesn't melt and ice sheets can
build.
cold autumns
extra cold winters so there is more snow.
cold springs
The development of a glacial period primarily requires cool summers, where temperatures remain low enough to prevent the melting of snow and allow for the accumulation of ice sheets.
These cool summers play a crucial role in building and sustaining glaciers. Additionally, cold autumns and winters contribute to the formation and growth of glacial ice by providing prolonged periods of cold temperatures and facilitating the accumulation of snow. The extra cold winters are particularly important as they ensure the preservation of snowfall and prevent it from melting. While cold springs are not directly essential for the development of a glacial period, they can contribute to the overall persistence of the icy conditions. Together, these factors create the necessary climate conditions for the formation and expansion of glacial periods.In conclusion, the development of a glacial period is primarily dependent on cool summers, which prevent snow melt and enable the formation of ice sheets.

ni
Answer:
A. extremely cold, dry winter months
Explanation:
Got a 100% on edge
The extremely cold, dry winter months are not a characteristic of a tropical wet and dry climate. Option A. is correct.
Tropical wet and dry climates are characterized by warm temperatures year-round, with a distinct wet season and a dry season.
The wet season is typically longer than the dry season, and it is during this time that most of the annual precipitation falls. The dry season can be quite dry, but it is not typically as cold as other tropical climates.
The characteristic that is not a characteristic of a tropical wet and dry climate is extremely cold, dry winter months. This is because tropical wet and dry climates are located in the tropics, where the temperatures are typically warm year-round.
So, Winters that are extremely cold, dry winters are not typical of a tropical wet and dry environment.

Think of an H-O world consisting of Chile and Australia, both of which make agricultural (A) and manufactured (M) goods with two factors of production, capital (K) and land (T). Australia is more land abundant (bigger T/K) than Chile, and A is the land-intensive industry compared to M.
(a) According to the H-O theorem, which country is going to have a comparative advantage in agriculture? In manufacturing? Explain why, in terms of the pre-trade price of T and K in each country.
(b) Draw an illustration of each country’s PPF if they are not trading, with A on the horizontal axis in each case. Given the assumptions of the H-O model, make sure to show how these two countries’ PPFs are different from each other.
(c) Pick an appropriate price of A relative to M for each country before trade (you can assume a 50-50 ratio in goods consumption in each country if you wish), and a reasonable international price that might be established once they began to trade. On a fresh pair of fully-labelled graphs, illustrate and explain how each economy would adjust output and consumption to the opening of trade.
(d) Who in Australia gains from trade when Australia opens to trade? Who loses? In Chile?
(a) Australia has more land relative to capital, the price of land (T) would be relatively lower in Australia compared to Chile, (b) Both countries have different PPFs due to their different factor endowments, (c) Its consumption of M will increase, and it will consume a combination of goods that lies beyond its initial PPF, (d) Consumers in Chile gain access to a wider variety of agricultural goods (A) at lower prices through imports.
(a) According to the Heckscher-Ohlin (H-O) theorem, a country will have a comparative advantage in producing the good that intensively uses its abundant factor of production. In this case, Australia is more land abundant (larger T/K ratio) than Chile.
Since agriculture (A) is the land-intensive industry, Australia would have a comparative advantage in agriculture. Conversely, Chile, being less land abundant, would have a comparative advantage in manufacturing (M), which is less land-intensive.
The pre-trade price of land (T) and capital (K) in each country will reflect their relative abundance.
Since Australia has more land relative to capital, the price of land (T) would be relatively lower in Australia compared to Chile.
On the other hand, the price of capital (K) would be relatively lower in Chile compared to Australia.
(b) Here is an illustration of each country's Production Possibility Frontier (PPF) if they are not trading:
Chile:
|
A |
| *
| *
| *
| *
| *
| *
|*________________________
0 M
Australia:
|
A | *
| *
| *
| *
| *________________________
0 M
In this illustration, A represents agricultural goods, and M represents manufactured goods.
Both countries have different PPFs due to their different factor endowments.
Chile, being less land abundant, has a relatively steeper PPF for agriculture (A) and a flatter PPF for manufacturing (M). Australia, with more land abundance, has a relatively flatter PPF for agriculture (A) and a steeper PPF for manufacturing (M).
(c) Let's assume that before trade, the price ratio of agricultural goods (A) to manufactured goods (M) in Chile is 1:2, and in Australia, it is 1:1.5. Also, assume that the international price ratio of A to M is 1:1.8.
Chile's adjustment to trade:
Before trade, Chile produces and consumes a combination of goods along its PPF.
After trade, since Chile has a comparative advantage in manufacturing (M), it will specialize in producing M and export it. With the international price ratio favoring M, Chile will increase its production of M and shift resources from agriculture (A) to M. Its PPF will expand outward in the M direction.
Chile will import more A due to its comparative disadvantage in agriculture. Its consumption of A will increase, and it will consume a combination of goods that lies beyond its initial PPF.
Australia's adjustment to trade:
Before trade, Australia produces and consumes a combination of goods along its PPF.
After trade, since Australia has a comparative advantage in agriculture (A), it will specialize in producing A and export it. With the international price ratio favoring A, Australia will increase its production of A and shift resources from manufacturing (M) to A. Its PPF will expand outward in the A direction.
Australia will import more M due to its comparative disadvantage in manufacturing.
Its consumption of M will increase, and it will consume a combination of goods that lies beyond its initial PPF.
(d) In Australia, those who gain from trade are the producers and exporters of agricultural goods (A).
Due to their comparative advantage in A, they can expand production and benefit from exporting to other countries at higher international prices. Consumers in Australia also gain from trade as they can access a wider variety of manufactured goods (M) at lower prices through imports.
On the other hand, those who might lose from trade in Australia are the producers of manufactured goods (M).
Due to the comparative disadvantage in manufacturing, some domestic manufacturers may face increased competition from imports, which could lead to a decrease in their production and potential job losses.
In Chile, the situation is reversed.
Those who gain from trade are the producers and exporters of manufactured goods (M) due to their comparative advantage. They can expand production and benefit from exporting M at higher international prices.
Consumers in Chile gain access to a wider variety of agricultural goods (A) at lower prices through imports.
Those who might lose from trade in Chile are the producers of agricultural goods (A).
Due to their comparative disadvantage in agriculture, they may face increased competition from imports, which could lead to a decrease in their production and potential job losses.

Hydrothermal Metamorphism involves chemical reactions between the oceanic lithosphere and warm fluids near mid-ocean ridges.
It is the result of the interaction of a rock with a high-temperature fluid of variable composition and occurs along mid-ocean ridge spreading centers where heated seawater percolates through hot, fractured basalt. The difference in composition between an existing rock and the invading fluid triggers a set of metamorphic and metasomatic reactions. Chemical reactions between the heated seawater and basalt result in metamorphism of the basalt.

The average sea level air pressure is 1013 millibars (mb) which
registers as 29.92 inches of mercury (in. Hg) on a barometer. If on
a given day the sea level pressure is 1003.00 mb, how many inches
of
On a given day when the sea level pressure is 1003.00 mb, we can convert this value to inches of mercury using the conversion factor.
To convert from millibars (mb) to inches of mercury (in. Hg), we can use the average value of 29.92 inches of mercury for 1013 millibars.
So, we can set up a proportion:
1013 mb = 29.92 in. Hg
1003 mb = x in. Hg
To solve for x, we can use cross multiplication:
1013 mb * x in. Hg = 1003 mb * 29.92 in. Hg
Simplifying the equation:
x in. Hg = (1003 mb * 29.92 in. Hg) / 1013 mb
Now, let's calculate the value of x:
x in. Hg ≈ 29.22 in. Hg
Therefore, on a given day when the sea level pressure is 1003.00 mb, it would be approximately 29.22 inches of mercury on a barometer.

referring to the figure, why did the well at point x dry up? choose one: a. the well at point x went dry because a sinkhole developed at point y, draining the aquifer. b. the well went dry at point x due to natural processes. over time, all wells go dry. c. overpumping of the well at point y caused drawdown. d. the well at point x went dry because many years of drought did not replenish the groundwater.
The reason why the well at point x dried up could be any of the options mentioned. However, the most likely cause is option C, overpumping of the well at point y caused drawdown.
Drawdown is the lowering of the water table in the area surrounding a well when water is pumped out faster than it can be replenished. This creates a cone of depression around the well, which can extend to neighboring wells, causing them to dry up. In the figure, we can see that the well at point y is located near the center of the cone of depression, indicating that it is being overpumped. As a result, the water level in the aquifer is lowered, causing the well at point x to go dry.
Option A, a sinkhole developing at point y and draining the aquifer, is possible but less likely. Sinkholes are typically caused by the collapse of underground caves and are not common in areas with a shallow water table like the one in the figure.
Option B, all wells going dry over time due to natural processes, is not accurate. While it is true that wells may eventually run dry, this typically takes many years and is not a natural process. It is usually caused by overpumping or drought.
Option D, many years of drought not replenishing the groundwater, could also be a contributing factor. However, the figure does not provide information on the climate or weather patterns in the area, so it is difficult to determine if drought is the sole cause of the well drying up.
In conclusion, the most likely reason why the well at point x dried up is due to overpumping of the well at point y causing drawdown.

what is the primary energy source that drives the hydrologic cycle and most other cycles on earth?
The Sun is the primary energy source that drives the hydrologic cycle and other cycles on Earth. The primary energy source driving the hydrologic cycle and other Earth cycles is the Sun.
Its energy causes water evaporation, cloud formation, and precipitation, and influences interconnected cycles like the carbon cycle. The Sun's energy plays a crucial role in powering various Earth processes. In the hydrologic cycle, the Sun's heat causes water bodies to evaporate, forming water vapor. This vapor then rises into the atmosphere, where it cools and condenses to form clouds. The energy from the Sun continues to drive the cycle as precipitation occurs, with rain, snow, or hail falling back to the Earth's surface. This water then flows into streams, and rivers, and eventually returns to the oceans, where the cycle begins again. The Sun's energy also influences other cycles, such as the carbon cycle and the water cycle, which are interconnected and vital for maintaining Earth's ecosystems.
