In the given right-angled triangle ABC, the length of AB = 5. (Option A)

In the right-angled triangle ABC, the ∠ B is a right angle, ∠C is 30° and the length AC = 10 which is the hypotenuse. AB is the perpendicular side opposite ∠C. In a right-angled triangle, the sine of an angle refers to the  ratio of side opposite to the angle (also called perpendicular) and hypotenuse. Hence, using the trigonometric function of sine,

Sin θ = Perpendicular/Hypotenuse

Sin 30 = AB/AC

Sin 30 = AB/10

In right-angled triangle, Sin 30 = ½

1/2 = AB/10

AB = 10/2 = 5

Answer:

Because coal burns at a slow rate for a long time, it's more efficient as an energy source than other fossil fuels.

But it is weird.

: )

Explanation:

It is weird to have so many coal deposits in cold regions of the earth because there is very less temperature and coal needs a high temperature to be produced.

Coal is a more effective energy source than other fossil fuels because it burns slowly and continuously.

Due to climate change and crustal plate tectonics, which occasionally pushed ancient continental masses through subtropical and even tropical regions, substantial coal deposits can be found in areas that presently have arctic or subarctic climates.

Other problems with mining minerals in Antarctica include the fact that weathering processes that concentrate minerals in other regions of the world don't occur there. The continent is frozen and has been for millions of years, with little to no liquid water moving.

Therefore, because there is relatively little temperature and coal needs a high temperature to be created, it is strange to have so many coal resources in chilly places on the planet.

Accretion is the process when subduction continues over a prolonged period, causing the colliding of volcanic arcs, oceanic plateaus, and microcontinents into the overriding plate.

Accretionary prisms are formed from sediment accreted into tectonic plates that dive below convergent plate boundaries. Most of the material in the accretionary prism consists of marine sediments eroded from subducting parts of the oceanic plate and in some cases also from the erosion products of volcanic island arcs that formed on the overlying plate.

Subduction zones or bending occur when the oceanic plate collides with the continental plate, and slides under the continental plate into the asthenosphere. Subducting plate boundaries form between continental plates and oceanic plates. In the event of this plate collision, the oceanic plate sinks / sinks under the continental plate at an angle of 45 degrees or more.

The dose response model that requires a certain level of exposure to the chemical be reached before any detectable harm results is the Threshold model. This is in contrast to the Non-threshold model.

This model suggests that below a certain exposure level, there is no effect on health, but once that threshold is exceeded, the harmful effects increase with increasing exposure. This is in contrast to the Non-threshold model, which assumes that any amount of exposure to the chemical can cause harm, and the Toxic response model, which assumes that the severity of the harm is directly proportional to the exposure level. The Linear model assumes that there is a linear relationship between exposure and harm, while the Inverted Response Curve model suggests that low and high levels of exposure may be less harmful than moderate levels. Overall, understanding the dose response relationship is important in determining safe exposure levels to chemicals and in protecting public health.

Humans impact on soils by damaging the structure of the soil (the shape of the soil peds). When the peds of soil are rounded it gives soil a crumby structure, which is the best structure for soil fertility. Overgrazing occurs when large numbers of animals are allowed to graze in one area for too long. In the Sahel region, animal ownership is considered the main criteria for defining wealth. Nomadic farmers allowed too many animals to graze the land than it had the ability to support, resulting in desertification. This is where the soil cannot sustain the herd numbers and is therefore gone beyond its ‘carrying capacity’. Herders then moved to marginal areas, which made the situation more dire. Alongside this nomadic farmers were gradually replaced by more sedentary farming practices and villages were established. Wells were sunk to provide water for animals; however, these wells used up groundwater further reducing soil fertility in the region. With an increasing population, more pressure on the land meant that farmers were forced to farm the land more intensively and remained in the one area for a longer period. Once the grazing animals removed the vegetation, the soil was exposed to the weather (wind erosion , also known as Aeolian erosion) resulting in soil erosion and eventual desertification.

When rocks are forced out of equilibrium, they undergo a process known as rock deformation.

This can occur through various mechanisms such as pressure, temperature, and tectonic forces. The rocks may begin to fold, fracture, or even flow under the stress.

This can lead to the formation of new geological structures such as mountains, faults, and folds.

Additionally, the movement of rocks can cause earthquakes, as the built-up pressure is suddenly released. The rocks may also undergo chemical changes as a result of the altered conditions, such as increased heat or pressure.

Overall, when rocks are forced out of equilibrium, it can lead to significant geological transformations and have important implications for the landscape and environment.

Scientists propose an early period of heavy bombardment in the Solar System because the Moon is heavily cratered.

A is the correct answer.

Failed planets and smaller asteroids crashed into larger worlds between 4.5 and 3.8 billion years ago, leaving scars on their surfaces. Impacts in the solar system may have increased near the end of the conflict, during a time known as the Late Heavy Bombardment.

The large planets were responsible for the Late Heavy Bombardment because as they moved about, circling closer and further from the sun, they pushed many asteroids and other smaller solar system objects with them.

Strong evidence for a period of intense bombardment can be found in the age distribution of meteors observed on Earth, major impacts on the terrestrial planets and our Moon, clues to shock impacts in the asteroid belt, and other factors.

Scientists propose an early period of heavy bombardment in the Solar System because the Moon is heavily cratered. So, the correct option is A. the Moon is heavily cratered.

The Moon has a lot of impact craters that indicate it has been hit by a lot of objects in the past. The craters on the Moon are not all the same age. Some are older than others. However, they all indicate that there was a time when the Moon was bombarded by a lot of objects. The smooth part of the Moon is nearly as old as the heavily cratered part, which suggests that the bombardment occurred early in the Moon's history.

The early period of heavy bombardment in the Solar System is thought to have happened about 4 billion years ago. During this time, the inner Solar System was full of debris left over from the formation of the planets. This debris included asteroids, comets, and other objects. These objects collided with the Moon and other planets in the inner Solar System, causing a lot of damage. The heavy bombardment period was not limited to the Moon.

Other objects in the inner Solar System also show evidence of being hit by a lot of objects during this time. The early period of heavy bombardment was a key event in the history of the Solar System. It is thought to have played a role in shaping the planets and their moons, and may have even played a role in the origin of life on Earth. So, the correct option is A. the Moon is heavily cratered.

Explanation:

Longitudes are imaginary lines that run from the north pole to the south pole of the earth.

Most water in the atmosphere has evaporated from the ocean, and most rain falls back into the sea. about 10% of the earth's total rain falls on land.

The water cycle demonstrates how water is constantly moving both inside the Earth and in the atmosphere. It is a complicated system with a wide range of processes.

Water vapour is created when liquid water evaporates, and this water vapour then condenses to form clouds and falls back to earth as rain and snow.

Different stages of water flow through the atmosphere. Runoff, infiltration, and percolation are three ways that liquid water moves across the land and through the earth. Plants absorb groundwater, which then evaporates from the plants and enters the atmosphere. Ice and snow that is solid can instantly turn gaseous. Water vapour can also solidify in the opposite situation.

Answer:

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from water solution.

Dry soil can be considered a low-loss dielectric at all specified frequencies (60 Hz, 1 kHz, 1 MHz, and 1 GHz) based on the given parameters of € = 2.5, H = 1, and 0 = 10^(-4) S/m.

To determine the behavior of dry soil at different frequencies, we can use the following guidelines:

- Good conductor: When the conductivity (σ) of the material is very high, indicating efficient electron flow and low resistivity. Good conductors have low loss (ε") and high permittivity (ε') values.

- Quasi-conductor: When the conductivity is moderate, indicating some resistance to electron flow. Quasi-conductors have moderate loss (ε") and permittivity (ε') values.

- Low-loss dielectric: When the conductivity is very low, indicating high resistance to electron flow and high resistivity. Low-loss dielectrics have low loss (ε") and permittivity (ε') values.

Given the values € = 2.5, H = 1, and 0 = 10^(-4) S/m for dry soil, we can calculate the other parameters:

a) At 60 Hz:

Using the formulas: σ = € * 0, ε' = 0 / (2π * f * €), and ε" = σ / (2π * f), we find σ = 0.00025 S/m, ε' = 0, and ε" = 0.0000042.

Conclusion: Dry soil at 60 Hz can be considered a low-loss dielectric.

b) At 1 kHz:

Using the same formulas, we find σ = 0.00025 S/m, ε' = 0, and ε" = 0.0000042.

Conclusion: Dry soil at 1 kHz can be considered a low-loss dielectric.

c) At 1 MHz:

Using the same formulas, we find σ = 0.00025 S/m, ε' = 0, and ε" = 0.0000042.

Conclusion: Dry soil at 1 MHz can be considered a low-loss dielectric.

d) At 1 GHz:

Using the same formulas, we find σ = 0.00025 S/m, ε' = 0, and ε" = 0.0000042.

Conclusion: Dry soil at 1 GHz can be considered a low-loss dielectric.

In summary, based on the given parameters, dry soil can be considered a low-loss dielectric at all the specified frequencies (60 Hz, 1 kHz, 1 MHz, and 1 GHz).

Sunspots are dark areas on the Sun's photosphere which are caused by intense magnetic storms.

The correct option is D.

These magnetic storms are generated by the Sun's powerful magnetic fields that extend outwards into the solar system. Sunspots are temporary disturbances in the Sun's surface which appear as dark spots and are associated with strong magnetic activity. Sunspots are often accompanied by other phenomena such as solar flares, coronal mass ejections and solar winds.

Sunspots usually occur in pairs, with one spot having a positive and one a negative magnetic polarity. They vary in size, shape and number over time, but typically last for about two weeks. Sunspots are important because they are associated with the Sun’s magnetic activity, which can disrupt the Earth’s magnetic field and cause space weather events.

Seafloor spreading is a geological process that occurs at divergent plate boundaries, where new oceanic crust is formed through volcanic activity and then spreads away from the ridge.

Seafloor spreading is important for the distribution of life on Earth because it contributes to the formation and evolution of the ocean basins, which in turn affects the composition of seawater and the distribution of marine organisms. This process plays a critical role in the exchange of heat, energy, and materials between the Earth's interior and the ocean. Seafloor spreading generates new crust and brings up nutrients from the mantle, which can support life.

As new crust is created, it also moves away from the mid-ocean ridges, creating zones of varying age and composition that can be exploited by different types of organisms. For example, hydrothermal vents and cold seeps, which are associated with seafloor spreading, are habitats for unique and diverse communities of bacteria, archaea, and animals that derive their energy from chemical reactions. Therefore, seafloor spreading plays a key role in shaping the biodiversity and biogeography of the world's oceans.

The result of the proof shows that the sum of the angles will be 180°.

In the question, we are told that angle a and b are a linear pair and this means that they are angles on straight lines. An angle on a straight line is 180°.

So, this means that if we find one angle, the other can be easily found by subtracting the known angle from 180°. Thus we can prove that the angles are supplementary by virtue of their sums. Let us say that one of the angles measures 90°, we can find the other by simply subtracting 90° from 180° to have 90°.
