Heating weakens the attraction between the molecules of a liquid, so its surface pulls less tightly. Surface tension arises because molecules at the surface are pulled inward by their neighbours, making the surface behave like a stretched skin.

For any real object, a convex mirror forms a virtual, erect and smaller image behind the mirror, between the pole and the focus.

A metal filament's resistance rises as it heats up, so the current falls and the resistor gets a smaller share of the voltage.

The stinging hairs of the nettle plant inject methanoic acid, also called formic acid, into the skin. Each nettle hair is a fine, brittle tube that breaks on touch and pushes its contents into the skin like a tiny needle.

These low-pressure systems travel east from the Mediterranean region and bring winter rain and snow to Kashmir and north-west India.

It contains hydrochloric acid and has a pH of about 1.5 to 2, the lowest of the four, so it has the most hydrogen ions.

A nanometre is 10⁻⁹ m and an ångström is 10⁻¹⁰ m, so one nanometre holds ten ångströms.

A plane mirror forms an image behind the mirror where light only seems to come from, with left and right swapped.

The lithosphere is the rigid outer shell of the Earth, made of the crust and the uppermost, solid part of the mantle.

Electric power equals voltage times current, so the current is 60 W ÷ 240 V = 0.25 A. The relation P = VI comes straight from the definitions: voltage is energy per unit charge and current is charge per second, so their product is energy per second, or power.

Its density is about 0.86 g/cm³, less than that of water, so it floats while it reacts. Potassium is an alkali metal, soft enough to cut with a knife.

Bacteria have peptidoglycan walls and animal cells have no wall, but fungal walls are made of chitin, not cellulose. Statement 1 is correct: peptidoglycan, also called murein, is a mesh of sugars cross-linked by short peptides; penicillin works by blocking its formation.

Meiosis halves them in the gametes, and fertilisation restores them in the offspring. Each parent makes gametes by meiosis, so a human egg or sperm carries 23 chromosomes instead of 46.

Two vanadium atoms must balance five oxide ions, each of charge −2, so each vanadium carries +5. In a neutral compound the oxidation states add up to zero.

As Viceroy, he issued the Resolution on Local Self-Government of 18 May 1882, remembered as its Magna Carta. Ripon, Viceroy from 1880 to 1884, wanted local boards and municipalities with a majority of elected, non-official members and an elected chairman where possible.

A liquid boils when its vapour pressure rises to match the pressure of the air above it. As a liquid is heated, more molecules escape as vapour and its vapour pressure climbs.

When light enters a denser medium, its wavelength is divided by the refractive index of that medium. The frequency of light is fixed by its source and does not change on refraction.

The summit was held there over two days, and the Secretary in the Ministry of Information and Broadcasting, Shri Chanchal Kumar, addressed its inaugural session before also opening the WAVES Global Investor and Investee Meet in the same city.

The white paper released by the Confederation of Indian Industry outlines a roadmap for India's media and entertainment sector to reach that size by the early 2030s, and it argues that faster reforms, stronger regional markets and measurable implementation are what would get the sector there.

The white paper was released at the CII Big Picture Summit held in Mumbai, and it lays out a roadmap for the Indian media and entertainment sector along with calls for quicker reform, stronger regional markets and implementation that can be measured.
