Answer:
2.765*10^-6
Explanation:
Simply move the decimal place to behind the 2. The number of places it moves is the power to the base (which will be always 10). The power will also be negative because it is less than 1.
distance east or west of the prime meridian is measured in degrees of?
Answer:
Longitude measure the distance east to west of the prime meridian that runs through greenwich england. Degrees are denoted by the greek word lamba.
Explanation:
Longitude gives us an angular measurement from 0 to 180 degrees. Subdivided into 60 minutes and 60 seconds. As longitude is singular at the poles. Earth's tectonic plates move relative to one another in different directions at the speed of 50 to 100mm per year so the movement sin tectonic plates influence the latitudinal rotation which changes from year to year. These vertical lines define the places on the earth with their approximate sea level surfaces. The longitudinal belt is the equator at the zero degrees largest longitude on earth.radio station broadcast at 85 megahertz what is the energy of each proton joule use 6.6times 10 to the negative 34 for the Planck constant

Q6 Is the effect of aerosols stronger or weaker than the effect of GHGs?
Stronger
Weaker
Answer:
weaker
Explanation:
Aerosol -
It is the suspension of the solid or liquid particles in the air , is known as the aerosol .
The effect of aerosol is , that it reduces the amount of the solar radiations incident on the surface of the Earth , and due to this capacity to reflect the solar radiations , it has a negative impact on the Earth .
Hence ,
The effect of aerosol is weaker than the GHG's .
Answer:
Weaker.
Explanation:
An aerosol is a fine suspension of solid or liquid droplets in air or any other gas. They can be natural or man-made. Examples include dust, fog, streams, etc. The size of particles has a major impact on their properties and diameter. Typically smaller than one micron. As compared to the impact of greenhouse gases these particles don't harm the natural environment in much extend as the GHGs have done so in the geologic period of the earth. GHGs concentration can form sooty particles and spread to larger distance the methane gas once react with the ozone can destroy it and cause hazardous problems, Impact of carbon monoxide and dioxide on the planet is seen as the impact of coal and industrial wastes.Which of the following represents 7.1×10-55 in standard notation?

Explain how political, economic, and religious forces can affect the diffusion of language.
Answer by using a minimum of 125 words.
Answer:
Explained as below
Explanation:
The political, economic, religious and other forces affect the diffusion of languages in any region as its due to the political features of the territory that the boundaries of one country that touch that of the another and this shows its location in relation to the other countries in the world. Ex of political boundaries. Economically any country on earth has its economy and which may or may not be dependent on the resource of the other nations is in direct relation to the interaction of one nation's language with those of the others. The lifestyles and ways of interactions have indirect communications on the languages in the country. Ex of trade flows. Social or religious factors have a direct bearing upon the linguistic diversity of the region as the so-called world is divided itself into 6 main religions like Christian, Muslims, Hindus, Buddhist, Jain, and jews and there are certain subclasses found within them thus, repeated Interaction of these elements leads to diffusion.Explain your interpretation of "sustainable development" as it might apply to
a)World population growth
b)The downtown core of a city
c)A thriving agricultural area
Answer:
"sustainable development"
Explanation:
Sustainable development implies that development that is based on the judicious use of resources as this implies over the entire earth. In terms of world population, this sustainable development can b understood in the form of a population explosion where the growth needs to balance and sustained in a fashion that does not affect the environment badly. A thriving agricultural area like the Ganges river system which is quite vulnerable to the changes brought in by the climatic reversals and hence needs to take care of and so that the areas don't have any drawbacks and development is not hindered. From the core of a city, it has to look at greener buildings and eco-friendly landscapes.Answer:
Explanation:
Sustainable development is the process of conservation of resources so that they remain available for present as well as for the future generations. The dynamics of the sustainable development can vary at different levels.
a)World population growth: The world population should be controlled from incremental increase every year more than the standard expected numbers. Thus resources conservation can become an issue under such conditions.
b)The downtown core of a city: A the city level the control in increase in size of the population should become the priority as well as the conservation of resources and the environment should be taken into consideration.
c) A thriving agricultural area: The agriculture area should be preserved by adding adequate amounts of minerals present in the manure and by crop rotation. This will help in preserving the quality of soil and further crops can be grown it for fulfilling the demand for future generations.
hich category of material properties does polarization fall under?
Magnetic
Optical
Electrical
Mechanical
Thermal
Answer:
optical
Explanation:
Polarization fall under optical property of material.
Polarization is a property of certain electromagnetic waves in which the direction and the magnitude of electric field are related in some way. Plane polarized light consist of waves in which direction of vibration of waves is same for all waves. Light may be polarized by reflection or by passing it through filters.
The population growth rate is a metric of how quickly a population increases in size. It is dependent upon the population's death and birth rates Human population growth rates fluctuate over time. For example, after the Industrial Revolution in the 18th century in Europe and North America, the human population growth rate soared because better health care and nutrition led to lower mortality rates. In the past few decades, human population growth has significantly decreased in some areas of the world. Despite a trend of lower birth rates in many regions during the past century, the global human population, which scientists estimated to be 7.5 billion in 2017, is increasing at a growth rate of just over 1%. the projected global human population in If Earth's population continues to grow at the current rate of 1.13%, what the year 2100? 25 billion 11 billion more than 30 billion 8-9 billion
Answer:
11 billion
Explanation:
The global population is constantly on the rise. There are significant demographic differences around the world, and i general they can be taken regionally.
Europe, the Americas, and East Asia tend to have low birthrates and low mortality rates. This leads to aging populations, and gradually the populations will start to stagnate and even decrease. On the other side, Africa, South Asia, Southeast Asia, the Middle East, are regions that have very high birthrates, and even though the mortality rates are much higher than the previously mentioned regions, they still manage to have big increase in their population. In a way, this disproportion is actually balancing the global population, so its rise is not as dramatic as in the past. It is expected that the population will continue to rise, but that the rise will constantly go down. The estimates are that by the year of 2100, the world will have a population of just above 11 billion people, 11.2 billion to be more precise.Answer:
I think the answer is, 11 billion

1. The sun is at an altitude of 30° to the horizontal. What is the corresponding air mass?
Answer:
Maritime tropical and continental tropical as they develop over the lower latitudes.
Explanation:
When the sun rays lie on in the place of 30-degree latitude in both the hemisphere the air mass acquires the characteristics of both maritime and continental. As the continental air masses are dry in nature and hence cover mostly the continental parts of the country as compared to the wet maritime air masses. These continental air masses are hot and humid nature and travel polewards. Normally monsoonal air masses reside over the ocean is and thus are cools and thus form what is called the trade winds. Other known popular places that produce these air masses are the Arabian peninsula and western landmasses. Sometimes their modification leads to the front formation and cyclone formations.Question 14(Multiple Choice Worth 3 points) Crust is recycled at hot spots. O mid-ocean ridges. trenches. rifts. transform faults.
Answer:
trenches
Explanation:
Crust recycling is the earth process by which surface matter from the land sphere is recycled into the mantle by the process of subduction or delamination. The crustal signs in mantle-derived rocks are thus a proof of the recycling. Most of this process happens through the mid-oceanic ridges. The development of whole mantle convection components and layered by mantle convection proponents. Evidence is suggested through the Seismic tomography and Stable isotopes that help in understanding the different layers on the earth and keeps track of the movements within the earth's crust. Dome group of researchers can find out that 5 to 10 % of the upper mantle is composed of recycled crustal matter.What is the long-term impact of population growth on supply and demand? Supply will decrease and demand will increase. Supply will remain constant and demand will decrease. Supply will increase and demand will decrease. Supply will increase and demand will increase. Supply will increase and demand will remain constant.
Answer:
Supply will increase and demand will increase
Explanation:
The supply and demand are connected with each other. The higher the demand, the higher the supply, and the lower the demand, the lower the supply on the market. This of course is determined by the number of consumers.
If the global population continues to grow, that means that there will be more and more consumers. The more consumers there are, the more goods will be demanded by them on the market. Since the demand will be on the rise, the producers will produce more in order to satisfy the demand, thus the supply will be on the rise.
Basically, larger population means more consumers, which in turn will result in an increase in demand, and an increase in demand will result in an increase in the supply.
Which one is the coldest layer in the atmosphere?
Question 56 options:
Troposphere
Mesosphere
Thermosphere
Stratosphere
The correct answer is B. Mesosphere.
Explanation
The mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere and below the thermosphere. Some of its main features are its thickness of 35 km, its temperature, because the mesosphere becomes colder as the distance from the Earth increases, that is, as the altitude increases. In warmer points, its temperature can reach -5 degrees Celsius, but at other altitudes the temperature can drop to -140 degrees Celsius, so it is considered the coldest of all layers.
On the other hand, the mesosphere is a protective layer for the planet, since it destroys most meteors and asteroids before they can reach the Earth's surface. So, the correct answer is B. Mesosphere.

What minerals are the most common in sediments and sedimentary
rocks? Give multiple reasons why they are most common.
Answer:
Sedimentary rocks are the rocks that are formed as a result of compaction and lithification of sediments. These are directly obtained from the sediments of the pre-existing rock. These sediments after weathering of the rocks are transported from one place to another with the help of agents such as wind, water, and ice. These sediments are then deposited at a different place. Then, it finally turns into sedimentary rocks. For example, Shale, Sandstone and Limestone.
The common minerals that are found to be present in the sedimentary rocks are feldspar, clay minerals, and mica. The sediments such as quartz and clay minerals are derived by chemical weathering of rocks that act as a cementing material holding the sediments together. These sedimentary rock-forming minerals are abundant on the earth's surface and are comparatively much stable. So, with time, they undergo compaction and solidification and forms sedimentary rocks.
2-1. Point A is at elevation 2690 feet and is located 520 feet due north of point B which is at elevation 2220 feet. Point C is at elevation 2340 feet and is located 250 feet N35°E of point B. What are the strike and dip of a unit whose upper surface was observed at each of these points?
The strike of the unit is 270° (due west) and the dip is 43° to the south.
To determine the strike and dip of the unit, we can follow these steps:
Calculate the elevation differences:
Elevation difference between A and B: 2690 ft - 2220 ft = 470 ft
Elevation difference between C and B: 2340 ft - 2220 ft = 120 ft
Determine the horizontal distances:
Distance between A and B: 520 ft (already given)
Distance between C and B: Project the 250 ft line in the N35E direction onto a line due east of B (since the strike is perpendicular to the dip direction). Using the cosine rule, we get:
BC^2 = AB^2 + AC^2 - 2 * AB * AC * cos(N35E)
BC^2 = 520^2 + 250^2 - 2 * 520 * 250 * cos(35°)
BC^2 ≈ 302,000
BC ≈ √302,000 ≈ 550 ft
Calculate the dip and dip direction:
Dip angle = tan^-1((elevation difference between A and B) / (horizontal distance between A and B))
Dip angle = tan^-1(470 ft / 520 ft) ≈ 43°
Dip direction: Since point A is north of B, the dip direction is due south (180°).
Calculate the strike:
Strike = dip direction + 90°
Strike = 180° + 90° = 270° (due west)
1. What happens in a ocean-continental collision?
a. montains form
b. continental plate subducts
c. new crust is formed
d. oceanic plate subducts
Answer:
A. Mountain forms
Explanation:
Its due to the continental plate is lighter than the oceanic plate the pale get subducted due to the slab push and slab pull effects. The continental plate further reaching the depth burns due to the pressure and intense temperature also this causing the melting of the rocks and leading to the formation of volcanoes and mountain chains of all sizes. Mountain forms and is composed of lava and basaltic matter from below. The collision of the plate leads to the formation of faults along the boundaries this led to the formation of the many large mountains on earth. The Himalayas are thereby known as the young fold mountains.What is evolution and how is natural selection related?
Answer:
Natural selection leads to evolutionary change
Explanation:
Natural selection is a process by which the species adapt to their environment. Thus individuals have a better chance of survival and evolution and transfer their traits to offsprings. As the process of evolution cannot take place without genetic mutation or diversification of genetic buildup. The occurrence of repeatedly branching events take place in which new species splits from a common ancestor producing a multi-level tree. For example, in the event of climate change, those species capable of tolerating the temperature will not die as compared to those which are not capable of tolerating and thus will not reproduce. If the same process is repeated over millions of years of the time the population will get adapted to their new climate and develop genes that combat these drastic changes.define pharmacokinetics. Name the four processes in pharmacokinetics and give an explanation of each.
Answer:
Pharmacokinetics is the analysis of how the body copes with absorption, distribution, metabolism & excretion of drugs under examination.
The four process of pharmacokinetics are absorption, distribution, metabolism and elimination.
Explanation:
Pharmacokinetics is the analysis of how the body copes with absorption, distribution, metabolism & excretion of drugs under examination. The impacts and length of the drug's action are also considered.
The four process of pharmacokinetics are absorption, distribution, metabolism and elimination.
1) Absorption - Absorption is the motion of a drug into the blood from its administration site. Many drugs are absorbed through passive absorption, but certain drugs require transportation mediated by the carrier.
2) Distribution - Distribution is the body wide motion of drugs
3) Metabolism - It is the method of transforming a drug throughout the body and make it much more hydrophilic in order for the kidneys to secrete it from the body.
4) Elimination - Excretion is the elimination from the body of the substance. Several drugs are either excreted unchanged or emit as urine or some other form.
Answer:
Answered
Explanation:
Pharmacokinetics is the branch of pharmacy which deals with the action of the body on the drug once it is administered in the body.
There are four process are followed when a drug is administered inside a body. These are absorption, distribution, metabolism and elimination or excretion.
Absorption is the movement of drug from its site of administration into the blood. Most drugs are absorbed by passive absorption but drugs need carrier mediated transport.
Distribution is the movement of drug through out body. Determined by the blood flow into tissues and cells.
Metabolism is the transformation of blood within the body to make it more hydrophilic so that it can be easily excreted out of the system.
Excretion is the removal of substances from the body. Some drugs are either excreted out unchanged and some are excreted out as metabolites.

If you have a square meter of soil with one plant and the plant photosynthesizes 2000 g of carbon per year and respires 1000 grams of carbon per year, what is the primary productivity of the square meter of soil?
Answer:
Primary productivity = 1000 gm/year/sq. meter
Explanation:
Primary productivity is defined as the difference betweeen main gross manufacturing and breathing energy. For the herbivorous, this is the energy available.
It is expressed as "gm/year/sq. meter" = gm/yr/m^2
or "kcal/year/sq. meter" = k cal/year/m^2
In the present case,
Gross primary production = 2000 gm/yr/m^2
Used for respiration purpose = 1000 gm/yr/m^2
So, Primary productivity = (2000 - 1000) gm/year/sq. meter
Primary productivity = 1000 gm/year/sq. meter
Question 7(Multiple Choice Worth 3 points) Minerals form during I. crystallization in magma. II. deposition from solution III. lithification in rocks I only Il only I and Il only I, II, and lIl
Answer:
I and Il only, crystallization in magma and dissolved in water.
Explanation:
Most of the minerals are formed due to the crystallization of lava or molten matter in due course of time when it slowly cools in contact with the land surface as in rapid cooling there is no time for the formation of crystals. Minerals are then formed from the evaporated of the solution a mix of substances dissolved in another. For example deposits of table salts. If the magma erupts to the surface and becomes a lava it tends to cool quickly and small crystals are formed. Depending upon the number of gases and chemical composition of lava.5. How do the number of miles between longitude lines at the equator compare to the same lines near the poles?
Answer:
Explanation given under.
Explanation:
A map is a two-dimensional representation of the earth and its features on the globe so, to represent this, the latitude and longitudes are imaginary lines that separate the northern and southern ends of the earth being divided the Geographic equator at 0 degrees. These alt longs create a type of grid that gives to the coordinate system of the earth. Like the circle, the latitude and longitudes are measured in degrees, minutes and seconds. The equator being in 360 degrees, the longitude values ranging from 180 degrees W to 180 E. As all longitudinal lines are equal at all places, they always cover the same distance as 60 miles. In contrast, the degrees of Latitude vary as near equator the degree of latitude is 60 miles but as you approach the poles the distance becomes zero. The range of latitude then is -90 (S) to +90 (N) degrees i.e tropic of cancer 23.5N, tropic of Capricorn 23.5S, and the Arctic and Antarctic circles at 66.5 N, S.How would changes in the average temperature of the troposphere affect the altitude of the tropopause?
Answer:
As the temperature inversion occurs around this zone
Explanation:
Troposphere The lowest layer of atmosphere found on the surface of the earth from 0 to 30 kilometers it's wider in equator i.e 18 km and narrows at poles till 6-8 km only. At this layer, 90 % of all convective activity takes place, turbulence and cloud formation like stuff. Consists of 80% of water vapor and dust particles. In troposphere the temperature in the air decrease with gain in height with a height of an overall positive lapse rate of 6.5 degrees C / km. The onset of tropopause the region where mixing stops and temperature remains constant and extends up to a layer of 11 to 20 kilometers. However, lapse rate variation sometimes occurs in between this sphere and affects the altitude of the tropopause. The seasonal effect is strongest at the mid-latitudes and varies with changes latitudes.
