Pradeep Kumar secured the bronze in the Men’s Discus Throw F43/F44/F62/F64 event at the Asian Para Games 2026 with the best throw of his own career, and the Prime Minister praised his commitment to pushing his own limits.

Devender Kumar took the gold, Rakesh the silver and Pradeep Kumar the bronze in the Men’s Discus Throw F43/F44/F62/F64 at the Asian Para Games 2026 on 20 October 2026, which accounts for every medal the event had to give.

He won the gold medal in the Men’s Discus Throw F43/F44/F62/F64 event at the Asian Para Games 2026 on 20 October 2026, and the Prime Minister described the throw as excellent and the victory as a celebration of the way Indian para sport is growing.

Para athletics groups competitors by the type and degree of their impairment and marks each group with a code, so a medal is always announced with that code attached.

Nishad Kumar had already won the long jump gold earlier at the Asian Para Games 2026, and on 20 October 2026 he added the Men’s High Jump T47 gold with a new Games Record, so he ended the meet with two gold medals.

Nishad Kumar won that title at the Asian Para Games 2026 on 20 October 2026, and the height he cleared was the best ever recorded at these Games in the event, which is why the gold is paired with a Games Record.

Nehru moved the Objectives Resolution in the Constituent Assembly on 13 December 1946, and the Assembly adopted it on 22 January 1947.

When natural gas or heavy oil burns with too little air, the carbon cannot all turn into carbon dioxide and separates as a very fine black soot, which is collected as carbon black.

Hydrated oxalic acid has a molar mass of 126 and is a dibasic acid, so its equivalent weight is 126 ÷ 2 = 63.

Iodine exists as diatomic molecules, I₂, in which two iodine atoms share a pair of electrons; so its atomicity is two, not one.

Here water only combines with calcium sulphate hemihydrate to form gypsum; no gas is given off and the paste simply sets hard.

Most carbon compounds are poor conductors of electricity, because their atoms are joined by covalent bonds and they do not form ions or free electrons that could carry a current.

Goldsmiths dip gold and silver ornaments in dilute nitric acid to dissolve the dirt, oxide layers and traces of base metals stuck to them, which brings back their shine.

Both statements are true, and the second explains the first: infrared waves are called heat waves because water molecules, present in most materials, absorb them readily and heat up.

Heat is energy in transit: it flows from a hotter body to a colder one only because their temperatures differ, and stops when they reach the same temperature.

The SI unit of inductance is the henry, symbol H, named after the American scientist Joseph Henry. Inductance measures how strongly a coil opposes a change in the current through it by producing an induced emf.

Plaster of Paris is calcium sulphate hemihydrate, CaSO₄·½H₂O, so one molecule of water is shared by two formula units of calcium sulphate, written (CaSO₄)₂·H₂O. It is made by heating gypsum, CaSO₄·2H₂O, to about 373 K (100 °C), when gypsum loses one and a half molecules of water per formula unit.

In the order visible light → ultraviolet → X-rays, the wavelength falls and the photon energy rises, so statements 1 and 2 are true and 3 is false.

In 1905 Einstein explained the photoelectric effect by treating light as made of packets of energy, later called photons, and he received the 1921 Nobel Prize in Physics for this work.

Light inside an optical fibre strikes the wall at more than the critical angle, is totally reflected back inside, and repeats this again and again along the fibre.
