\(\dfrac{w}{2}-12=18\)
The value of w can be solved as follows :
Add 12 to both sides,
\(\dfrac{w}{2}-12+12=18+12\\\\\dfrac{w}{2}=30\)
Cross multiplying, we get :
\(w=2\times 30\\\\w=60\)

Note that the area of the windshield that is swept by the wiper blade is approximately 54π² or 1696.5in² (Option A)
What is the explanation for the above response?To find the area swept by the wiper blade, we need to know the length of the path that the wiper blade follows as it moves across the windshield. We can use the length of the swinging arm and the angle of rotation to calculate this.
When the arm rotates 120 degrees, the wiper blade sweeps out an arc of a circle with a radius of 24 inches (the length of the swinging arm). The length of this arc can be found using the formula:
length of arc = (angle in radians) x (radius)
To convert the angle in degrees to radians, we multiply by π/180:
120 degrees x π/180 = 2π/3 radians
So the length of the arc swept by the wiper blade is:
length of arc = (2π/3) x 24
= 16π inches
Now we can use the length of the arc and the length of the wiper blade to find the area swept by the wiper blade. The area swept by the wiper blade is approximately equal to a sector of a circle with radius 18 inches and central angle 120 degrees. The area of this sector can be found using the formula:
area of sector = (angle in radians) x (radius)² / 2
Again, we need to convert the angle to radians:
120 degrees x π/180 = 2π/3 radians
So the area swept by the wiper blade is:
area of sector = (2π/3) x (18)^2 / 2
= 162π/3
= 54π in² or 1696.5in²

At the june solstice, day length varies from ________ hours at the equator to ________ hours at the north pole.
Answers
At the June solstice, day length varies from 12 hours at the equator to 24 hours at the North Pole. The summer solstice, also known as the June solstice, is the longest day of the year. The date varies from year to year, but it always falls between June 20 and June 22.
The June solstice is the point on the calendar when the sun's path in the sky is farthest north. As a result, it is the northern hemisphere's summer solstice and the southern hemisphere's winter solstice. During this time, the day is longer than the night. The closer you are to the equator, the less variation you'll see in day length throughout the year. At the equator, the day length is roughly 12 hours all year
. However, as you move closer to the poles, day length becomes more variable. At the North Pole, the sun never sets during the June solstice, resulting in 24 hours of daylight. In contrast, during the winter solstice, the North Pole experiences 24 hours of darkness.

Answers
From west and east compass directions the greatest differential stress coming.
All changes in mineral composition and rock texture that occur in rocks within the Earth's crust as a result of chemical reactions under conditions of high temperature and differential stress are referred to as metamorphism.
There are two basic categories of metamorphic rocks: those with foliation because of environments with directed pressure or shear stress, and those without foliation because of environments without directed pressure or with very little pressure at all as compared to the surface.
A rock is likely to be deformed during metamorphism when it is crushed under directed pressure, and this might cause the minerals to elongate in a direction perpendicular to the main stress. Foliation is formed as a result of this.
Differential stress is the ability of materials like rocks to withstand stresses of various intensities and orientations. Differential stress is the term used to describe the difference between the biggest and smallest stress.
Always acting at right angles are the highest and lightest stresses. The plane containing the largest and smallest stress behaves normally in the presence of an intermediate stress.

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?
Answers
(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.

Define Passive Margin .The locations where continents have rifted apart and separated by an ocean are marked as passive margins, also known as rifted margins. In other words, passive margins are wedges of continental crust that taper toward the sea, are split by faults, covered by sedimentary basins, and abut oceanic crust.
What traits distinguish a passive margin?The Atlantic and Gulf coasts exhibit the traditional characteristics of a passive continental margin, including a low-lying coastal plain, a wide continental shelf, a steep continental slope, a mild continental rise, and a flat abyssal plain.

Answers
Spits and baymouth bars are formed through the deposition of sand and other sediments by longshore currents, beach drift, and wave action.
A spit is a long, narrow ridge of sand or gravel that extends from the mainland into a body of water. It is formed by the deposition of sediment by longshore currents and beach drift, which transport sand along the shoreline. As the sediment is deposited, it gradually builds up and extends further out into the water. Spits are often curved or hooked at the end, due to changes in the direction of the currents or changes in wave energy.
A baymouth bar is a sandbar that completely or partially blocks the entrance to a bay or lagoon. It is formed when sediment is deposited across an inlet or bay by longshore currents and beach drift, creating a barrier that separates the bay from the ocean. The bar can be formed from a combination of both erosion and deposition, as wave action cuts away at both sides of a long sand bar, leaving a sand ridge aligned parallel to the shore.
