CDS Previous Year GK Questions

This is the full form of SWAYAM, the Government of India's free online course platform. SWAYAM was launched in 2017 by the Ministry of Education (then the Ministry of Human Resource Development).

Resistivity equals resistance multiplied by area and divided by length, which leaves the unit ohm × length.

Under Article 56, the President resigns by writing to the Vice-President of India, not to the Speaker of the Lok Sabha, so this statement is not correct.

Fiscal deficit is total expenditure minus total receipts other than borrowings, so it shows how much the government must borrow in a year.

Jointed legs are the mark of the phylum Arthropoda, to which insects belong; an earthworm has no legs at all.

These gases react with water in the air to form sulphuric and nitric acids, which fall as acid rain. Sulphur dioxide comes mainly from burning coal and oil in power plants and smelters, and nitrogen oxides from vehicle engines and high-temperature furnaces.

Resistance varies inversely with the area of cross-section, and doubling the diameter makes the area four times larger. The resistance of a wire is R = ρl/A, where ρ is the resistivity of the metal, l the length and A the cross-sectional area.

At about 5,895 m, it is the highest peak in Africa and the tallest free-standing mountain in the world. Kilimanjaro is a dormant volcano in north-eastern Tanzania, close to the Kenyan border.

Bacteria and fungi cannot break down most plastics, so plastic waste stays in soil and water for hundreds of years.

With the velocity changing steadily from 5 m/s to 7 m/s, the average velocity is 6 m/s, and 6 m/s × 3 s = 18 m. For uniform acceleration, displacement s = ((u + v)/2) × t. Here u = 5 m/s, v = 7 m/s and t = 3…

This is the taxonomic hierarchy for animals, going from the broadest group down to the most specific. Linnaeus built this ladder of ranks, and each rank contains one or more ranks below it.

A temperature in kelvin is the Celsius temperature plus 273 (more exactly 273.15). The Kelvin and Celsius scales have degrees of the same size, so a change of 1 °C equals a change of 1 K; only their zero points differ.

When actual (equilibrium) real GDP is below the output the economy could produce at full employment, the shortfall is called a recessionary gap.

Common fertilisers supply nitrogen, phosphorus and potassium (NPK); iron is a micronutrient that is usually not part of them. Plants need nitrogen, phosphorus and potassium in large amounts, so these are called primary macronutrients, and fertilisers such as urea, DAP, MOP and NPK mixtures are made to supply them.

Litmus is a natural dye extracted from certain lichens, especially species of Roccella. A lichen is a partnership between a fungus and an alga (or a cyanobacterium): the alga makes food by photosynthesis, while the fungus gives shelter and absorbs water and minerals.

An ammeter measures the electric current flowing in a circuit, in amperes. An ammeter is always connected in series with the part of the circuit whose current is to be measured, so that the whole current passes through it.

Convergence of different schemes and the use of ICT for real-time monitoring are both core strategies of POSHAN Abhiyaan. POSHAN Abhiyaan (Prime Minister's Overarching Scheme for Holistic Nourishment), also called the National Nutrition Mission, was launched on 8 March 2018 at Jhunjhunu in Rajasthan.

By origin, resources are either biotic, which come from living things, or abiotic, which come from non-living things. Biotic resources are obtained from the biosphere and have life: plants, animals, fish, livestock and human beings.

The ozone hole is a sharp seasonal thinning of the stratospheric ozone layer over Antarctica, caused mainly by chlorine from chlorofluorocarbons.

If you hold a current-carrying straight wire in your right hand with the thumb pointing along the current, your curled fingers show the direction of the magnetic field lines around it.
