The difference in the readings on the dry and wet bulb thermometers is used to determine?
Detalles de la respuesta
The difference in the readings on the dry and wet bulb thermometers is used to determine the relative humidity of the air. The dry bulb thermometer measures the ambient temperature of the air, while the wet bulb thermometer measures the temperature with the effect of evaporative cooling. The difference between the two temperatures, known as the "wet bulb depression," is a function of the humidity in the air. By comparing the wet bulb depression to a chart or calculator, you can determine the relative humidity of the air. Relative humidity is the amount of moisture in the air compared to the maximum amount the air can hold at a given temperature. So, the difference in readings on the dry and wet bulb thermometers can tell you how much moisture is in the air, which allows you to calculate the relative humidity.

The most prominent feature of River Haba downstream of the bridge is a
Detalles de la respuesta
A levee is a man-made embankment designed to prevent flooding. A knickpoint is a steep slope or waterfall that interrupts a river's longitudinal profile. A meander is a winding curve or bend in a river's course, caused by erosion and sediment deposition. A braid is a complex network of river channels separated by small, often temporary, islands or sandbars. Given the context of the question, the most likely answer is a meander, as downstream of a bridge is often where meanders can be found in a river's course. Meanders are common in rivers with low gradients and high sediment loads, where the river erodes the outer bank of a bend and deposits sediment on the inner bank, causing the channel to migrate over time.

Pregunta 8 Informe
A government policy which is likely to encourage massive importation of goods into a country is the?
Detalles de la respuesta
A government policy that is likely to encourage massive importation of goods into a country is the relaxation of currency control. This policy involves easing restrictions on the movement of currency in and out of a country, which makes it easier for businesses to import goods from foreign countries. When currency controls are relaxed, it becomes easier for businesses to access foreign currencies, which they can use to pay for imports. As a result, there is a higher likelihood of massive importation of goods into the country. This policy can be detrimental to local industries, as it can lead to increased competition from foreign goods, which may be cheaper and of higher quality, leading to the decline of local industries.

In river transport, the problem of irregular levels of water can be overcome by?
Detalles de la respuesta
In river transport, irregular levels of water can cause problems for ships or boats to navigate safely. Therefore, a solution is needed to overcome this issue. Building locks and canals is a solution to the problem of irregular water levels. Locks are structures that are built in rivers to raise or lower boats or ships from one water level to another. Canals are artificial waterways that are built to provide a navigable route between two bodies of water, usually at different elevations. By using locks and canals, boats and ships can navigate through a river system that has different water levels and avoid getting stuck or damaged. Changing the direction of flow, clearing water weeds, or controlling the current are not direct solutions to the problem of irregular levels of water in river transport.
Pregunta 15 Informe
The feature is one of the landforms association with
Detalles de la respuesta
The feature mentioned in the question is most likely associated with river erosion. Rivers are powerful agents of erosion that shape the land by carrying sediment, cutting through rocks, and carving out valleys. River erosion can create distinctive landforms such as waterfalls, canyons, and meandering channels. Therefore, the feature being referred to is likely a landform created by the erosive action of a river. Wind deflation, wave erosion, and wind deposition are not directly related to river erosion and do not typically produce similar landforms.

The survival of an organism in a natural ecosystem depends largely on?
Detalles de la respuesta
An organism's survival in a natural ecosystem depends largely on its adaptation to prevailing conditions. This means that the organism must have physical and behavioral traits that enable it to survive in its environment. For example, an organism may have a specialized digestive system that allows it to break down certain types of food found in its habitat, or it may have evolved camouflage to help it blend in with its surroundings and avoid predators. Without these adaptations, an organism would be unable to thrive and reproduce in its natural environment.
Pregunta 17 Informe
The difference between towns and villages is that?
Detalles de la respuesta
The difference between towns and villages is that towns typically perform more tertiary functions than villages. Tertiary functions refer to services such as banking, education, healthcare, entertainment, and other non-primary and non-secondary economic activities. Villages, on the other hand, are typically more focused on primary activities such as agriculture and fishing, and may have limited access to tertiary services. Therefore, towns are generally more developed and have a higher concentration of infrastructure and services than villages.

Some of the physical properties of soils are?
Detalles de la respuesta
Some of the physical properties of soils include texture, structure, and porosity. Soil texture refers to the size of the particles that make up the soil. Soil can be classified as sandy, loamy, or clayey depending on the predominant particle size. Soil structure refers to how the particles are arranged and aggregated. Soil can be granular, blocky, or platy, depending on the way the particles are arranged. Porosity refers to the amount of space between the soil particles, which affects the soil's ability to hold water and air. Other physical properties of soil can include things like color, which can indicate the presence of certain minerals, and alkalinity or acidity, which can affect plant growth. However, texture, structure, and porosity are three of the most important physical properties of soil, as they can have a significant impact on the soil's fertility, water-holding capacity, and overall health.

An example of a rock formed by wood subjected to pressure and heat is?
Detalles de la respuesta
An example of a rock formed by wood subjected to pressure and heat is lignite. Lignite is a type of coal that is formed from peat, which is partially decomposed plant material. Over time, peat can be buried and subjected to high pressure and temperature, causing it to undergo a process of coalification. During this process, the plant material in the peat is gradually transformed into coal. Lignite is the lowest rank of coal, and is characterized by its brownish-black color and relatively low energy content. Lignite is formed from the compression and heating of wood, which is a type of plant material. So, lignite is an example of a rock formed by wood subjected to pressure and heat.

The proportion of workers in the iron and steel industry in relation to the total number of workers in the town is
Detalles de la respuesta
To find the proportion of workers in the iron and steel industry, we need to first determine the actual number of workers in that industry. We can do this by multiplying the total number of workers in the town (25,000) by the percentage of workers in the iron and steel industry (115.2/360 x 100 = 32%). Number of workers in iron and steel industry = 25,000 x 32% = 8,000 The proportion of workers in the iron and steel industry in relation to the total number of workers in the town is therefore: Proportion = Number of workers in iron and steel industry / Total number of workers in town Proportion = 8,000 / 25,000 Proportion = 0.32 Therefore, the answer is 0.32.

What is the birth rate of a country with a total population of 150,000,000 and registered births of 3,000,000 in a given year?
Detalles de la respuesta
The birth rate of a country is the number of births per 1,000 people in a given year. To calculate the birth rate of the country with a total population of 150,000,000 and registered births of 3,000,000 in a given year, we need to divide the number of registered births by the total population and then multiply by 1,000. So, the birth rate of the country is: (3,000,000 / 150,000,000) x 1,000 = 20 This means that for every 1,000 people in the population, there were 20 births in that year. To convert this into a percentage, we can divide the birth rate by 10, which gives us: 20 / 10 = 2% Therefore, the birth rate of the country is 2%.
