Sodium hydroxide dissolves in water and splits completely into Na+ and OH- ions; the ions carry current and the hydroxide ions make the solution strongly basic.

Powers of lenses in contact simply add, so the combination has a power of 2 + 2 = 4 dioptre, and its focal length is 1/4 m, that is 0.25 m. The power of a lens is the reciprocal of its focal length in metres, P = 1/f, and is…

Naneghat is a mountain pass in the Western Ghats of Maharashtra, known for Satavahana cave inscriptions, not for a Chola Shiva temple.

Parenchyma is the basic packing tissue of plants, and it is also present in both xylem (xylem parenchyma) and phloem (phloem parenchyma).

Oxidising power of the halogens falls as we go down group 17, so iodine is the weakest and fluorine the strongest oxidising agent.

Urea, CO(NH2)2, contains about 46 per cent nitrogen, the highest of any common solid fertiliser, and is the main nitrogen fertiliser used in India.

The primary structure of a protein is simply the linear order of amino acids joined one after another by peptide bonds.

This statement is false: diamond is an electrical insulator because it has no free electrons. In diamond, every carbon atom uses all four of its valence electrons to form strong covalent bonds with four other carbon atoms in a rigid three-dimensional network.

The live demonstration of Shrutlekh at the symposium showed speech being written down as it was spoken and translated at the same moment, a capability intended for lecture halls, research seminars, conferences and academic discussions.

The figures placed before the symposium were that BHASHINI supports 36 Indian languages for text, 23 Indian languages for voice and 35 international languages, that it has recorded over 10 billion cumulative AI inferences, and that its website translation plugin works on more than 800 government websites.

BHASHINI Pragati is a document translation workbench that the Digital India BHASHINI Division built for the CAG, and it was put before the symposium as an example of translating structured documents, including files that run from 100 to 500 pages, with quality checks and data-security safeguards.

The 29th International Symposium on Electronic Theses and Dissertations, shortened to ETD-2026, was held at the Indian Institute of Technology Delhi from 23 to 25 October 2026, and the Digital India BHASHINI Division took part in it with a session on its multilingual artificial intelligence tools.

The name comes from the Greek words for naked and seed: gymnosperms bear seeds that are not enclosed in a fruit, and most of them are woody, evergreen trees.

Clean sand is made almost entirely of quartz, which is silica or silicon dioxide, and silica is the main ingredient of glass.

A magnetic field pushes a moving charge sideways, and the push on a negative charge is opposite to that on a positive one, so the two kinds bend away from each other.

In rusting, iron combines with oxygen in the presence of water to form hydrated iron oxide, and the addition of oxygen is oxidation.

When muscles run short of oxygen, the pyruvate formed from glucose is converted into lactic acid instead of being broken down fully.

Water gas is a mixture of carbon monoxide and hydrogen, made by passing steam over red-hot coke. The reaction is C + H2O → CO + H2, carried out at about 1,000 degrees Celsius.

At the boiling point, water turns into vapour inside the liquid itself, and these pockets of steam are the bubbles that rise and burst at the surface.

Light travels fastest in vacuum and almost as fast in air, so in any material medium it moves more slowly than in air, and the ratio of the two speeds is greater than one.
