Questions that students in your age group are asking from across India

The atomic masses of all the atoms in a formula unit of a compound are added to determine the formula unit mass of a substance. Ions are the component particles of the formula unit mass, whereas atoms are the component particles of the formula molecular mass.

During the First World War, the British army engaged in forced recruiting from India's rural districts. High customs tariffs and income taxes were levied to pay for the cost of the military. Additionally, harvests in many areas of India failed between 1918 and 1919 and again between 1920 and 21. This led to severe food shortages. All of this greatly fueled resentment and hostility toward British colonial authority, and the national movement in India moved in that direction.

Echo is the term for the recurrence of sound brought on by its reflection from a solid surface. To achieve a clear echo, the following factors are crucial: A minimum of 17 metres should separate the sound's source and reflector. The reflector's size needs to be sufficient about the sound wave's wavelength.

Three types of heat transmission exist; Conduction: Heat is transmitted from an object's hotter end to its cooler end through the process of conduction. Convection: Convection is the method through which heat is transferred through a fluid (such as a liquid or gas). Radiation: Using radiation, heat may be transferred without the use of a medium.

A smooth or uniform surface produces a regular reflection. In a typical reflection, all reflected rays for parallel incident rays are parallel to one another. An uneven surface causes irregular or dispersed reflection. For parallel incident rays, diffused reflection results in rays that are not parallel to one another. This occurs as a result of the existence of erratic tiny surfaces. Therefore, incident parallel rays reflect in various directions. Each ray does, however, abide by the rules of reflection. Diffuse or irregular reflections do not, therefore, break the principles of reflection.

While serving as the Governor-General of India from 1848 to 1856, Lord Dalhousie mostly adhered to the Doctrine of Lapse, an annexation strategy. According to this, the East India Company would seize any princely state if the sovereign lacked a legitimate male successor and was under its direct or indirect (as a vassal) power. No son of the Indian monarch who had been adopted could be declared the heir to the throne. This questioned the Indian king's long-held right to choose his or her successor.

More than 85% of the net planted land of Punjab, Haryana, and Western Uttar Pradesh is irrigated. In these states, irrigation is mostly used to cultivate wheat and rice. In Punjab, 76.1 per cent and in Haryana, 51.3 per cent of the total net irrigated area is watered by wells and tube wells, respectively. This demonstrates that these states have used a significant percentage of their groundwater capacity, leading to groundwater depletion.

When it has recently rained, and the water droplets are suspended in the air, a rainbow may be seen in the sky opposite the sun. The sun's light ray enters the water droplet and experiences surface refraction, which reaches the other end and is internally reflected, revealing dispersion into seven colours. Consequently, the combined effects of refraction, internal reflection, and dispersion result in rainbow production.

Connective tissue has several purposes, including insulating, aiding in the binding and support of the organs, supporting them, giving the body form, retaining body heat, and storing energy.

The two most crucial causes for this were as follows: The Mughals did not want Turks and Iranians to unite and overthrow the emperor. The Mughals also desired to involve the military castes of the subcontinent in the administration of the mansabdri system. As a result, the Mughals hired mansabdars from the Rajput, Sikha, Marathas, Dessani, Afghan, and Indian Muslim castes in addition to the Turani and Irani groups.

The central bank of India is the Reserve Bank of India (RBI). A statutory entity, RBI. It is in charge of controlling the flow of money into the Indian economy as well as issuing currency notes. By the RBI Act of 1934, RBI was created on April 1st, 1935. The banker's bank, the custodian of foreign reserves, the controller of credit, and managing the printing and supply of currency notes throughout the nation are some of the key responsibilities of the RBI.

The muscles work in pairs. Muscles move body parts by contracting and then relaxing. Muscles can pull bones but can't push them back to their original position. When one of them contracts, the bone is dragged in the same direction, and the other muscle in the pair relaxes in response. To move the bone in the opposite direction, the relaxed muscle contracts to pull it towards its original position while the first relaxes. All a muscle can do is pull.

The Parliament enacted the RTI Act, which applies to all governmental institutions established by the States and Union Territories as well as government agencies at the federal level. The Act applies to the Panchayati Raj Institutions (Part IX) of the Indian Constitution. It provides citizens with the right to access Panchayat information. Governmental works, records, and papers are open to public inspection.

(i) Mercury is a metal that is liquid at room temperature. (ii) Sodium is a metal that can be cut with a knife easily. (iii) Silver is the finest metal for transferring heat. (iv) Metals that are poor conductors of heat are mercury and lead

The high-powered money is the total liability of the country's monetary authority and RBI. It refers to the money produced by the RBI and the government of India. It includes; currency in the hands of the public, cash reserve of commercial banks and other deposits with RBI. H = C+ R Where, H = high-powered money C = currency and R = cash reserves with commercial banks

With a 50 million-year margin of error, the age of the Earth is calculated to be 4.54 billion years. Scientists have scoured the Earth, searching for the oldest rocks to date radiometrically. They found rocks that were 4.03 billion years old in northwest Canada. Then scientists found minerals in Australia that were around 4.3 billion years old. Because the rock cycle makes it clear that rocks are continually recycled, researchers kept looking for information elsewhere. Scientists examined moon rocks gathered during the moon mission and even meteorites that have crashed on Earth since it is believed that the bodies in the solar system may have originated at comparable times. These two minerals have an age of 4.4 to 4.5 billion years.

When molten rock rises to the surface, volcanoes erupt. When the Earth's mantle melts, magma is created where tectonic plates separate or are driven beneath one another, and melting may occur. This magma rises towards the Earth's surface because it is lighter than rock. Gas bubbles develop inside the magma as it rises. Runny magma erupts from cracks or vents in the Earth's crust, then turns into lava and rises to the surface. Gas bubbles cannot easily escape from thick magma, which results in pressure building with rises magma. An explosive eruption may occur under excessive pressure, which can be harmful and devastating. When water below the surface mixes with heated magma and produces steam, an eruption can also occur.

The Russian Revolution of 1917 ended with the October Revolution, the second and last significant component of the revolution. The Bolshevik Revolution is another name for it. Trotsky commanded the Military Revolution Committee, which was able to get the backing of the Petrograd Garrison and Kronstadt sailors. In October 1917, the Prime Minister ordered the arrest of Bolshevik leaders, which sparked an armed rebellion in Petrograd on October 25th. The Bolsheviks spearheaded the revolution, occupying government buildings on October 25th. The Winter Palace was taken the next day. It was the headquarters of the Provisional Government, which was formed when the Tsars were deposed. The Bolsheviks eventually evolved into the Communist Party of the Soviet Union. Vladimir Lenin was in charge of the new government.

The sun and the weather combine to create a rainbow. As light passes through a water droplet, it slows and bends as it passes from air to denser water. The light bounces off the interior of the droplet, separating the wavelengths—or colours—that make up the droplet. A rainbow is created as light exists in the droplet.

The moon's gravity has helped slow Earth's rotation from a six-hour day to our present 24-hour day, as well as maintaining the tilt of our planet's axis and so regulating the seasons. As a result, life forms on a moonless Earth would have diverse activity patterns depending on the short days and nights. Without it, life may never have emerged. Living creatures would have very different behaviour patterns to deal with the six-hour day and significant temperature fluctuations that a moonless Earth would experience.

There are now 195 nations around the globe. This figure includes 193 United Nations member nations and two non-member observer states, the Holy See and the State of Palestine. Around 54 countries in Africa, 48 in Asia, 44 in Europe, 33 in Latin America and the Caribbean, 14 in Oceania and 2 in Northern America total makes up the 195 countries in the world.

Rayleigh scattering is responsible for the sky's blue colour. The scattering of electromagnetic radiation (of which light is a kind) by particles with a considerably shorter wavelength is referred to as this scattering. In basic words, the sky is blue because blue light from the Sun is scattered over the sky and down to our eyes by the air. Air is made up of a zillion microscopic things, the most of which being nitrogen molecules. When sunlight travels millions of kilometres across our atmosphere, these things disperse a little quantity of light. Blue light is scattered more by nitrogen molecules than by other colours. As a result, a small amount of blue light bounces about in the sky before entering our eyes. The sky seems to be blue as a result of this.

The countries such as Pakistan, Afghanistan, China, Nepal, Bhutan, Myanmar and Bangladesh share the land boundaries with India. The following is the shortcut trick to learn the countries’ names easily. Short cut trick: Ba Ch Pa N mei M B A ( Bangladesh, China, Pakistan, Nepal, Myanmar, Bhutan and Afghanistan)

These are the polymers nucleotide composed of hydrogen, oxygen, carbon, nitrogen, and phosphorus. It controls the basic function of the cell. It was first reported in 1971 by Friedrich Miescher from the nucleus of a pus cell. For the first time, Altmann referred to it as nucleic acid. They are discovered in the nucleus and help transmit genetic data.

In Chemical Kinetics, a chemical reaction is the conversion of one or more compounds (reactants) into one or more distinct substances (products). Chemical elements or compounds are examples of substances. A chemical reaction rearranges the component atoms of the reactants to produce various products.

Combustion is the process of releasing carbon dioxide, water, heat, and light from a carbon molecule in the air. Carbon and its components create carbon dioxide, vapor, heat, and light when they are burnt in the air. Heat energy = Hydrocarbon + Oxygen The combustion reaction is represented by the formula above. The majority of carbon compounds burn in the atmosphere, producing a great deal of heat. When alkanes, for example, burn in the air, they create a lot of heat, making them ideal fuels.

The Union Home Minister Amit Shah inaugurated the National Tribal Research Institute in New Delhi to celebrate the Azadi ka Amrit festival. The institute will offer all the resources to the tribal community. It will provide the policy input to the Minister of Tribal Affairs and State Welfare Department to introduce the program and studies which support the socio-economic development of the tribes.

India has fertile land which is favorable for the cultivation of crops. Around two-thirds of the population depended upon agriculture as they acquire the skills from their ancestors. Favorable climatic conditions such as temperature, rainfall, humidity, and monsoon climate all these factors led the agriculture as a primary activity in the country.

Mansabdars were paid by income assignments known as jagirs, which were similar to iqtas. The Mansabdars did not live in or govern their jagirs; instead, they merely had rights to the money generated by their assignments, which was collected for them by their servants when the mansabdars themselves were serving elsewhere in the nation.

These are the organic molecules produced by living organisms and act as a building block of life. It performs an important function in living organisms and is composed of carbon, hydrogen, oxygen, Sulphur and phosphorous. Proteins, Nucleic acids, Lipids and Carbohydrates are the most common biomolecules.

Ashoka wanted to solve numerous problems. People in the empire followed different religions, which sometimes led to conflicts. Salves and servants were ill-treated. Animals were sacrificed, and there were quarrels between the family and the neighbours. He felt it was his duty to solve these problems.

Atom is the smallest unit of the element, which is extremely small and cannot be predictable through the naked eyes. It consists of the three fundamental types of particles: protons, neutrons, and electrons. For example, N, H, He, O, K, etc.

Amine has basicity of 23.5. This is due to the amines' lone pair of electrons on nitrogen atoms.

The presence of the -OH group in ethanol allows it to create hydrogen bonds with water molecules, which makes it soluble in water. In other words, because ethanol is a polar solvent, it dissolves in water.

The Nile River is thought to be the world's longest river. The "Father of the African River" is another name for it. It stretches about 6650 kilometres. The river's source is thought to be Lake Victoria. The river's two tributaries are the Blue and White Niles, and it flows through 11 countries.

The Sun is around 150 million kilometres away and even being on top of the Everest only brings you 9 kilometres closer to the Sun, which makes a small difference to make you feel warmer. When you pressurise air (or any other gas), it becomes hotter, and when you let off the pressure, it becomes cooler. As a result, the pressure drops as the air rises. The cooler temperature on top of a mountain is due to the reduced pressure at higher elevations.

Fossil fuels are combustible geologic deposits of organic matter, such as dead plants and animals, that have been buried beneath thousands of feet of sediment. Due to the intense heat and pressure inside the earth's crust, these deposits decomposed over time and were changed to natural gas, coal, and petroleum. They are also regarded as non-renewable energy sources since they require a long time to refill.

National Education Policy is based on the recommendation of the Kasturirangan and T.S.R. Subramanian committees. It is built on the four foundational pillars that are Access, Quality, Equity and Affordability. It aims to implement several changes in the education system of India from school to college level and focus on making “India a global knowledge of superpower”. Before the introduction of NEP 2020, there were two earlier policies brought in the years 1968 and 1986.

The purpose of the Directive Principle of State Policy is to lay down the positive instructions which will guide the state policy at all levels.

A figure of speech is a means of clearly and creatively describing something or someone. The words or phrases may not imply precisely what they indicate, but they create a vivid image in the reader's or listener's mind. A phrase or a single word can be used as a figure of speech. Rhetorical figures are sometimes known as figures of speech.

Given, D= 945 km T= 7 hours Distance covered by car in 1 hour = 945/7 = 135km Thus, Distance covered by car in 9 hours = 135 x 9 = 1215 km

When a conductor carrying current is subjected to an external magnetic field, it feels a force, according to Fleming's left-hand rule. This force is perpendicular to both the magnetic field and the direction of current flow. Fleming's left-hand rule does not determine the magnitude; rather, it just reveals the direction of the parameter – current, magnetic field, and force – when the direction of the other two parameters is known.

Average Speed can be defined as the total distance covered by the object at a particular time interval. It is a scalar quantity which means it doesn’t have a direction it is mainly represented by the magnitude.

Granite is the most common igneous rock. When magma cools beneath Earth’s surface, it forms granite. It consists of minerals such as mica, quartz and feldspar. It is usually white, grey or pink in colour. Mainly used for making statues, floors, kitchen and counters.

Solar and lunar are the two types of eclipses. Solar eclipses happen when the Moon passes between the Earth and the Sun, casting a moving shadow on the planet's surface. When the Earth passes between the Sun and the Moon, a lunar eclipse occurs, creating a shadow on the Moon.

The Greek terms phos (pronounced "fos") and σύνθεσις(pronounced "synthesis") are combined to form the phrase "photosynthesis." Phos is a Greek word that signifies "bright" and "combines." This is defined as "combining with the aid of light."Photosynthesis is the conversion of sunlight, carbon dioxide (CO2), and water into food (sugars) and oxygen by plants, algae, and some microorganisms. The formula for photosynthesis, would look like this: 6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2

In the early 1970’ s some timber contractors went to cut the trees in the Terai forest of Garhwal in Uttrakhand. Some local women decided to prevent this deforestation and were ready to give up their lives to prevent them from being cut. This movement is called Chipko Movement and it gradually spread to the entire country. Sundrlal Bhugana, Gaura Devi and Chandi Prasad Bhatt are some famous leaders of this movement.

Ozone is the molecule formed by the three atoms of oxygen known as isotopes of oxygen. The primary purpose of the ozone layer is to shield the earth's surface from the sun's harmful UV radiation. These rays are toxic to living things and can cause skin cancer.

Corbett National Park, sometimes known as Jim Corbett National Park, is a national park in Uttarakhand India.

Genes are DNA segments that are tightly coiled into chromosomes. A gene is made up of a particular nucleotide sequence. A nitrogenous base, a sugar molecule, and a phosphate group make up a nucleotide.

There is a two-hour time difference between Gujarat and Arunachal Pradesh. As a result, the time along India's Standard Meridian (82° 30' E) passing through Mirzapur (in Uttar Pradesh) is used as the country's standard time. Otherwise, different parts of India would have different timings, causing complications; so, a single universal standard time for the whole country has been chosen and named Indian Standard Time (IST).

Capillaries are the thinnest blood vessels. Small, thin blood vessels that link the arteries and veins are known as capillaries. Their thin walls enable oxygen, nutrients, carbon dioxide, and waste products to flow through.

The renowned Chola dynasty's temples represent their mastery in building, art, and bronze casting. These temples were built by Raja Raja Chola I and Rajendra and are mainly famous for their architectural and sculptural marvels. These temples have conferred the title of UNESCO world heritage site in 1987.

Kabaddi is the national game of Bangladesh. It is also known as Ha-Du-Du or the "game of rural Bengal," and is played according to different rules depending on where it is played.

The heat produced by a 100 W heater in 2 minutes will be given by Energy = P× =100 × 2 × 60 = 12000 J = 12.0 kJ

Higher the oxidising potential, higher is the tendency to lose an electron, and higher is the reducing nature, so the order is Y>Z>X.

Mitoplasts are mitochondria with their outer membrane peeled away while retaining their inner membrane intact.

Ionic compounds are generated when one or more electrons are transferred from one atom to another, and these ions have a stronger attractive force than their repulsive forces. The ions form a crystalline structure by arranging themselves so that they have the least amount of potential energy. As a result, the ions can't move and can't conduct electricity.

The new national flag of the Republic of South Africa was unfurled at midnight on April 26, 1994, marking the birth of a new democracy in the world. It resulted in a foundational change in political scenery and ushered in a new constitutional legal order unprecedented in the country's history.

The addition is affected by the associative property. As a result, you can add three or more numbers in any order and get the same result. "As per associative property: A + (B + C) = (A + B) + C A × (B × C) = (A × B) × C"

Banking is a process whereby the outer edges of a road are raised to a certain height while the inner edges are kept at a lower level. The angle of inclination of the road is usually about 2 degrees. Banking is done so as to minimise the wear and tear of the tyres while in curved motion. When a vehicle traces a circular path, a centripetal force acts towards the centre, thereby increasing the friction between the road and the tyres. On banking the road, however, some component of gravity (due to inclination) compensates for the centripetal force. This minimises the friction, thereby reducing the wear and tear of the tyres.

Specific heat is defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1-degree Celsius. In other words, we can say that on being supplied with external heat energy, a substance with a high value of specific heat will absorb more heat energy in order to reflect a temperature increase as compared to another substance that has a lower specific heat value. In a power plant, the job of a coolant is to keep the system cool by absorbing as much heat energy as possible. Therefore, the value of specific heat for a coolant must be high.

States of matter are represented by the changes in the macro and micro properties of a substance with changing external conditions (primarily temperature and pressure). Typically, we know of four primary states of matter that can easily be observed. These include Solids, Liquids, Gases, and Plasma. However, scientists believe there can be as many as 22 states of matter in existence! These states are not found under normal conditions but can be found in the extremities of the universe and some of them can even be observed in a laboratory. Some of these include: Bose-Einstein Condensate (BEC), Super Critical Fluid, Super Solid, Quantum Spin Liquid, etc.

As we know, free electrons in a conductor get attracted to the positive end of the conductor. When electricity conducting material is subjected to an external electric field, positive and negative elements within the conductor get separated. The velocity with which the negative elements (electrons) drift towards the positive end of the conductor is known as drift velocity. Mathematically, it is defined as: vd = (eE/m).T where, vd = Drift Velocity e = Electron Charge E = Strength of the external electric field m = Mass of the electron T = The average relaxation time

Steam has more heat content than liquid water at 100 degrees. This is because of something known as the latent heat of evaporation. As liquid water approaches a temperature of 100 degrees, it does not immediately get converted into steam. It is simply water at 100 degrees. Now, when we further heat the liquid water beyond this point, the temperature of the water does not change. This is because the heat energy being supplied is spent in weakening the molecular bonds, which helps water transit from liquid to gaseous state. Therefore, the steam present has a heat content equivalent to that contained by liquid water at 100 degrees plus the latent heat required to convert liquid water into steam.

Sulphurous acid two acidic radicals can be derived.

Russia has the largest deposits of iron in Europe.

The scientific study of how people's ideas, feelings, beliefs, intentions, and aspirations are formed in a social environment via actual or imagined interactions with others is known as social psychology.

An earthquake is a strong surface shaking caused by movement in the earth's mantle or volcanic activity.

(2,3)R; (1,2)R; (1,2)R; (1,2)R; (1,2)R; (1,2)R; (1,2) If (2,1),(3,2)R, R is symmetric. R=(1,1),(2,2),(3,3),(2,1),(3,2),(2,3),(1,2) is now equal to R=(1,1),(2,2),(3,3),(2,1),(3,2),(2,3),(1,2) If (3,1);(1,3)R, R is transitive. As a result, R becomes and (1,1)(2,2)(3,3)(2,1)(3,2)(1,3) equivalence relation by adding (1,1)(2,2)(3,3)(2,1)(3,2)(1,3) (1,2). Hence, There are a total of seven ordered pairs.

Whenever a bacterial population comes into contact with a specific antibiotic, those sensitive bacteria perish. However, certain bacteria develop resistance to the antibiotic due to mutations. As the competitive bacteria die, such resistant bacteria survive and reproduce swiftly. Resistance-producing genes increase quickly, and the entire bacterial population becomes resistant. Hence they are pre-existing variations in the population.

Planck's constant is one of the fundamental physical constants of the universe. It is defined as the change in energy of a substance with respect to a unit change in it's frequency. Mathematically, this can be expressed as h = E/f, or E = hf (where E = Energy, f = frequency, h = Planck's constant). The magnitude of Planck's constant (h) is 6.626 x 10^-34 Js.

Significant digits in a quantity include all the digits included in a quantity that carry a well-defined meaning. The given quantity here is 0.0060320 m. We can express this as 6.0320 x 10^-3 m. Since all non-zero numbers in any quantity are significant, 6, 3, 2 are significant. Also, all zeroes that are placed between non-zero digits (i.e which are neither leading nor trailing) are also significant. Additionally, all zeroes to the right of a decimal place are counted as significant digits as they specify a meaning (they may be used to signify the measuring ability of the measuring system). Therefore, the total number of significant digits is 5.

Isotropic amorphous materials have the same thermal and optical characteristics in all dimensions. Hence are They are anisotropic is incorrect.

Ernst Mayr proposed the "Biological Species Concept," which helped develop the present synthesis of evolutionary theory. According to which species is the most fundamental unit of life and the only one that exists.

Albert Einstein discovered the Theory of Relativity. The theory of relativity usually refers to two connected ideas devised and published by Albert Einstein in 1905 and 1915, respectively: special relativity and general relativity

For someone unfamiliar with the concept, the very first instinct would be to say a^2 + b^2. However, this is incorrect. Let us understand this through a simple example. Let there be two numbers: 3 and 5. (3 + 5)^2 = 82 = 64 But, 3^2 + 5^2 = 9 + 25 = 34 This clearly suggests that (a + b)^2 is not equal to a^2 + b^2. But why does this happen? (a + b)^2 simply means (a + b) * (a + b) = a*a + a*b + b*a + b*b = a^2 + ab + ba + b^2 = a^2 + 2ab + b^2 Therefore, the correct interpretation of (a + b)^2 is a^2 + 2ab + b^2.
