Article 17 abolishes untouchability and forbids its practice in any form, making it a fundamental right enforceable against private individuals as well as the State. Article 14 guarantees equality before law and Article 15 prohibits discrimination on specified grounds, but neither uses the word untouchability.
The Director General of Police is the senior-most officer of the state police force and heads the Odisha Police organisation. Inspectors General, Deputy Inspectors General and Superintendents command ranges or districts under the DGP's overall control.
The Brahmani is formed by the union of the South Koel and Sankh and flows wholly within Odisha before draining into the Bay of Bengal near Dhamra. The Mahanadi rises in Chhattisgarh and the Subarnarekha passes through Jharkhand and West Bengal as well.
The Konark Sun Temple is ascribed to Narasimhadeva I of the Eastern Ganga dynasty and is dated to the thirteenth century CE. It is designed as a colossal chariot with wheels and horses, and is a UNESCO World Heritage Site.
The Kalinga war is generally dated to about 261 BCE in the thirteenth year of Ashoka's reign, and the suffering it caused led him to adopt Dhamma. The rock edicts, particularly the Thirteenth Major Rock Edict, record his remorse.
Deomali, located in the Koraput district in the Eastern Ghats, is the highest peak in Odisha at over 1,600 metres. Mahendragiri is a prominent peak in Gajapati district but is lower than Deomali.
The 42nd Amendment Act of 1976 inserted Part IVA containing Article 51A, listing the Fundamental Duties of citizens on the recommendation of the Swaran Singh Committee. A later amendment added the duty of parents to send children to school.
Recruitment to the post of Sub-Inspector of Police in Odisha is conducted through the Odisha Police Recruitment Board, which issues notifications and conducts the written examination and physical tests. The OPSC handles civil service posts, while the OSSC handles several group C posts.
Ahmedabad was inscribed as a UNESCO World Heritage City in 2017, becoming the first Indian city to receive that status. Jaipur was inscribed later, in 2019, for its planned walled city.
The Right to Information Act was enacted in 2005 and came into force on 12 October 2005, giving citizens a statutory right to seek information from public authorities. It replaced the earlier Freedom of Information Act, which was never fully operationalised.
Similipal in Mayurbhanj district is a biosphere reserve and also a tiger reserve, noted for its sal forests and melanistic tigers. The Nilgiri, Sundarbans and Nokrek biosphere reserves lie in other states.
MGNREGA guarantees at least 100 days of unskilled manual wage employment to every rural household whose adult members volunteer to do so. The Act was enacted in 2005 and renamed after Mahatma Gandhi in 2009.
Among the states adjoining Odisha, Chhattisgarh shares the longest boundary, running through the western districts. Andhra Pradesh lies to the south, West Bengal to the north-east and Jharkhand to the north.
Madhusudan Das, known as Utkal Gourab, founded the Utkal Sammilani in 1903 to press for the unification of Odia-speaking tracts. The organisation played a major role in the creation of a separate Odisha province in 1936.
Part IV, comprising Articles 36 to 51, contains the Directive Principles of State Policy, which are fundamental in the governance of the country but are not directly enforceable in courts. Part III contains the enforceable Fundamental Rights.
The Sambar deer is the state animal of Odisha, while the state bird is the Indian roller and the state tree is the sacred fig. The elephant is the state heritage animal, which is a separate designation.
Chilika is Asia's largest brackish water lagoon, connected to the Bay of Bengal and known for its migratory birds and Irrawaddy dolphins. Its salinity varies with the sea mouth and the inflow of rivers.
The writ of habeas corpus commands the person detaining another to produce the detainee before the court and justify the detention. It protects personal liberty and can be sought against both state and private action.
The Union Cabinet conferred classical language status on Odia in 2024, along with several other languages, recognising its ancient literary heritage. The earlier classical languages included Tamil, Sanskrit, Telugu, Kannada and Malayalam.
A constable is the entry-level rank, above which comes the Sub-Inspector, then the Inspector, and then officers of the deputy superintendent level. This hierarchy determines who supervises whom in a police station and subdivision.
Under Article 155 the Governor is appointed by the President, and under Article 156 holds office during the pleasure of the President, normally for a term of five years. The Governor is not elected by the state legislature.
Barabati Fort stands in Cuttack on the bank of the Mahanadi and was built by the Ganga rulers, later serving as a seat of the Gajapati kings. Its ruins and the adjoining stadium are well-known landmarks of the city.
The dispute centres on dams and barrages built upstream in Chhattisgarh, which Odisha argues reduce water availability in the lower basin and affect irrigation and flood patterns. A tribunal was constituted to adjudicate the sharing of waters.
The Swaran Singh Committee recommended the addition of Fundamental Duties, which were then incorporated by the 42nd Amendment in 1976. The duties are drawn from the Indian tradition and the Constitution of the erstwhile USSR.
Above the Deputy Superintendent of Police comes the Additional Superintendent of Police, followed by the Superintendent of Police. This ordering reflects the gazetted hierarchy of the state police force.
Article 315 of the Constitution mandates that there shall be a Public Service Commission for the Union and a Public Service Commission for each State. It is the foundational provision for bodies such as the Odisha Public Service Commission, which conducts recruitment for state services including the post of Sub-Inspector of Police.
The Odisha Special Armed Police is a reserve force of the Odisha Police that provides armed assistance to district police for law and order duties, riot control, and counter-insurgency operations. It is not tasked with economic crime investigation, traffic regulation, or prison management, which are handled by other specialized wings.
The Kalinga Ratna is the highest civilian award of the Government of Odisha, instituted in 1992. It recognizes individuals for outstanding achievements in fields such as literature, art, science, and public service. The other options are either not state awards or are lesser-known honors not officially designated as the highest civilian award.
Community policing is a strategy that emphasizes collaboration between the police and citizens to identify and solve local problems, thereby reducing crime and enhancing public confidence. It is not about infrastructure expansion, VIP protection, or traffic enforcement, which are separate functions.
The Odisha Human Rights Commission was constituted in 2000 under the Protection of Human Rights Act, 1993, which applies to states. It has the power to inquire into complaints of human rights violations by public servants, among other functions. Therefore, both statements are correct.
Rods are the photoreceptor cells of the retina that respond to very low light intensity and support night (scotopic) vision, though they do not distinguish colour. Cones need brighter light and provide colour and sharp detail. Hence dim-light detection is chiefly a function of the rods.
Skeletal muscle is striated and under voluntary control through somatic motor nerves, which is why it drives rapid limb movement in sprinting. Smooth muscle is involuntary and found in the walls of internal organs, while cardiac muscle is confined to the heart. Connective tissue does not contract.
An element is a pure substance made of only one kind of atom and cannot be decomposed into simpler substances by chemical reactions. A compound contains two or more elements chemically combined and can be broken down. Mixtures and colloids contain more than one component.
The ampere is the SI base unit of electric current, defined in terms of the flow of electric charge per unit time. The volt measures potential difference, the ohm measures resistance, and the watt measures power. Hence current is recorded in amperes.
In the liquid state, intermolecular forces hold particles close enough to give a fixed volume, but the particles can slide past one another, so the liquid takes the shape of its container. Solids have both definite shape and volume, while gases have neither. Plasma is an ionised gas and also lacks a definite shape or volume.
Vitamin C (ascorbic acid) is required for the synthesis of collagen, so its deficiency causes scurvy, marked by bleeding gums, delayed wound healing and weakness. Rickets results from vitamin D deficiency, beri-beri from thiamine deficiency, and night blindness from vitamin A deficiency. Each deficiency therefore produces a distinct disorder.
Using the kinematic equation s = ut + ½at² with initial velocity u = 0, acceleration a = 4 m/s² and time t = 5 s, we get s = 0 + ½ × 4 × 25 = 50 m. The zero initial velocity removes the ut term entirely. Thus the body covers 50 m in the first five seconds.
The work done against gravity is mgh = 50 × 10 × 2 = 1000 J. Average power is work divided by time, so P = 1000 J / 5 s = 200 W. The time factor converts energy into power, which is why the answer is not simply the work value.
This is the Doppler effect for sound: when the source moves towards a stationary observer, successive wavefronts are emitted from progressively closer points, so the wavelength shortens and the observed frequency rises. The emitted frequency is unchanged, but the received frequency is higher. The shift depends on relative motion, not on any change in the siren itself.
By the law of conservation of mass, the mass of the compound equals the mass of hydrogen plus the mass of oxygen that combines with it. A 1:8 ratio means 1 g of hydrogen combines with 8 g of oxygen, giving a total of 9 g of the compound (water). The combined mass, not the oxygen mass alone, is the answer.
Plant cells possess a rigid cell wall made chiefly of cellulose outside the plasma membrane, which gives shape and mechanical support; animal cells lack this wall. Both plant and animal cells are eukaryotic with a nucleus and mitochondria, and both have a plasma membrane. The cell wall is therefore the reliable distinguishing feature.
In the AB blood group, both A and B antigens are present on the red blood cell surface, and the plasma contains neither anti-A nor anti-B antibodies. This is why AB individuals are called universal recipients of red cells. The presence of an antigen is matched by the absence of its corresponding antibody.
Ohm's law states that current equals voltage divided by resistance, I = V/R. Substituting V = 5 V and R = 10 Ω gives I = 5/10 = 0.5 A. The result is less than one ampere because the resistance is larger than the voltage in magnitude.
Common table salt is sodium chloride, formed by the ionic combination of one sodium ion (Na⁺) with one chloride ion (Cl⁻), giving the formula NaCl. Sodium carbonate, sodium bicarbonate and sodium hydroxide are different compounds with distinct uses. Hence NaCl is the correct formula for table salt.
Vitamin D promotes the absorption of calcium from the intestine and its deposition in bone. A combined deficiency therefore reduces calcium available for mineralisation, producing soft, weak bones such as rickets in children and osteomalacia in adults. The two nutrients act together, so deficiency of either compounds the effect.
Metallic bonding involves a lattice of positive metal ions surrounded by a sea of delocalised electrons, which are free to move and carry current in the solid state. Ionic solids conduct only when molten or dissolved, and covalent molecular solids generally do not conduct. Hence metallic bonding explains conduction in the solid.
For two equal resistors in parallel the equivalent resistance is half of one resistor, so R = 6/2 = 3 Ω. The total current is then I = V/R = 12/3 = 4 A. Equivalently, each branch carries 12/6 = 2 A and the branch currents add to 4 A.
In a perfectly inelastic collision, total momentum is conserved: m₁u₁ + m₂u₂ = (m₁ + m₂)v. Here (2 × 6) + (4 × 0) = 6v, so 12 = 6v and v = 2 m/s. Kinetic energy is not conserved in such a collision, but momentum is.
A group B person carries anti-A antibodies, so group A blood would be agglutinated and cannot be given, while group O red cells lack A and B antigens and are accepted. Group A and AB recipients could receive group A blood, and group O could receive only group O. Thus the victim is most probably group B.
Boyle's law states that at constant temperature the pressure of a fixed mass of gas is inversely proportional to its volume (PV = constant). Halving the volume therefore doubles the pressure, because the same number of molecules strikes a smaller wall area more frequently. The relationship is inverse, not linear or squared.
