Static General Knowledge makes up the rest of the General Awareness section in RRB NTPC, and the notices name its topics: General Science and Life Science up to Class 10, History of India and the freedom struggle, Physical, Social and Economic Geography of India and the world, Indian Polity and Governance, Indian Economy, Art and Culture, Indian Literature, Monuments and Places, Flora and Fauna, Famous Personalities, the UN and other world organisations, environmental issues, Transport Systems in India, Important Government and Public Sector Organisations, Common Abbreviations, and Basics of Computers and Computer Applications. RRB frames these as short factual questions: the unit of a physical quantity, the year of a battle, the article of the Constitution, the river a city stands on, the full form of an abbreviation, the headquarters of an organisation. GK24's GK notes on this page cover each topic in English and Hindi, arranged the way the syllabus lists them, with the facts RRB tends to ask placed first. Work through one topic at a time, note the lists (national parks, dances, articles, schedules, awards), and pair each topic with its quiz on GK24 to check what has stayed with you.
If a particle is moving with simple harmonic motion, the velocity is _________ at the mean position.
In simple harmonic motion the velocity is given by omega times the square root of A squared minus x squared.

Read the full explanation →A metallic wire having resistance of 20 Ω is cut into two equal parts in length. These parts are then connected in parallel. The resistance of this parallel combination is equal to
Each half of the wire has a resistance of 10 Ω, and two 10 Ω resistors in parallel give 5 Ω. The resistance of a wire is R = ρL/A, so it is directly proportional to its length when the material and thickness stay the same.

Read the full explanation →Two convex lenses have focal lengths of 50 cm and 25 cm, respectively. If these two lenses are placed in contact, then the net power of this combination will be equal to
For lenses in contact the powers simply add, and here they are +2 D and +4 D. The power of a lens is the reciprocal of its focal length in metres, P = 1/f, and its unit is the dioptre.
Read the full explanation →Deendayal Port was earlier known as :
Kandla Port in the Kutch district of Gujarat was renamed Deendayal Port in 2017 after Pandit Deendayal Upadhyaya. Kandla was developed in the 1950s on the Gulf of Kutch to replace the trade that India lost when Karachi went to Pakistan at Partition.

Soap micelles are large enough to scatter the light passing through the solution, and this scattering makes soapy water look cloudy.
Read the full explanation →Who among the following was the advisor to the Constituent Assembly?
Sir Benegal Narsing Rau was appointed Constitutional Adviser to the Constituent Assembly and prepared its first draft of the Constitution in October 1947.

The Kaleshwaram Lift Irrigation Project is built on the Godavari river in Telangana and is often described as the world's largest multi-stage lift irrigation scheme.
Read the full explanation →Which one of the following biosphere reserves comprises islands with estuaries, beaches, coral reefs, salt marshes and mangroves ?
Lying between India and Sri Lanka off Tamil Nadu, it is built around a chain of 21 small islands with estuaries, beaches, coral reefs, salt marshes, seagrass beds and mangroves.
Read the full explanation →Consider the following statements about cavalry warfare in India : 1. The iron stirrup made it possible for the armoured warrior to sit firmly on a horse without falling off. 2. The iron stirrup also allowed a cavalry charge with lances held tightly to the body, without the rider being thrown off by the shock of impact. Which of the statements given above is/are correct ?
The iron stirrup gave the rider a firm seat, and that firm seat made the lance charge possible, so both statements are correct.
Read the full explanation →Which of the following groups of planets is termed as 'gas planets' as they are composed primarily of lighter ices, liquids and gases?
These four outer planets are the gas planets, also called Jovian planets, made mostly of hydrogen, helium, ices and liquids rather than rock.
Read the full explanation →Which of the following statements about the Panchayats in India, as per the Constitution of India is/are correct ? 1. There is a provision for reservation of seats for the Scheduled Castes and Scheduled Tribes. 2. Panchayats are not authorised to collect taxes. Select the correct answer using the code given below :
The Constitution reserves seats in Panchayats for Scheduled Castes and Scheduled Tribes, and it also lets Panchayats levy and collect taxes, so statement 2 is false.
Read the full explanation →Which of the following statements regarding insolation is/are correct? 1. Insolation is predominantly short-wave radiation, with wavelengths in the range of 0.39 micrometre to 0.76 micrometre. 2. Insolation is evenly distributed across the Earth because of the Earth's curved surface. Select the correct answer using the code given below.
Insolation, the incoming solar radiation, arrives mainly as short waves centred on visible light, but the Earth's curved surface spreads it unevenly, so statement 2 is false.
Read the full explanation →Which of the following statements regarding Arc Volcanoes is/are correct ? 1. Arc volcanoes are found near divergent plate boundaries. 2. Some of the world's classical examples of cone-shaped stratovolcanoes, such as Mount Fuji in Japan, Mayon in the Philippines are Arc volcanoes. 3. Some of the highest volcanoes on Earth are of the Arc type, notably Nevado Ojos del Salado in the Chilean Andes. Select the answer using the code given below :
Arc volcanoes form above subduction zones at convergent plate boundaries, not at divergent ones, so statement 1 is false while 2 and 3 are true.
