The correct answer is C) Four.
Major Indian languages belong primarily to four language families: Indo-European (specifically the Indo-Aryan branch), Dravidian, Austroasiatic, and Sino-Tibetan.
The vast majority of India’s population speaks languages from the Indo-European and Dravidian families. The Austroasiatic and Sino-Tibetan families are spoken by smaller, but significant, populations, mainly in eastern, central, and Himalayan regions. While other minor language families or isolates exist (like Andamanese), the four listed are considered the major families spoken in India.

The correct answer is D) Tripura.
Tripura shares an international border with only one country, Bangladesh, which surrounds it on its north, west, and south sides.
Let’s examine the other options:
A) Arunachal Pradesh shares borders with Bhutan, China, and Myanmar (three countries).
B) Assam shares borders with Bhutan and Bangladesh (two countries).
C) Mizoram shares borders with Bangladesh and Myanmar (two countries).
Thus, Tripura is the only state among the given options that shares an international border with only one country.

The correct answer is D) river Kavery.
The Krishna Raja Sagara Dam (KRS Dam) is built across the Kaveri (Cauvery) river in the state of Karnataka, India. The reservoir created by the dam is also known as Krishna Raja Sagara.
The dam was constructed by Bharat Ratna Sir M. Visvesvaraya, then Diwan of Mysore, during the reign of Krishnaraja Wadiyar IV of Mysore. It is a major source of irrigation water for the surrounding areas and also provides drinking water to Mysore and Bengaluru cities.

The correct answer is C) Cartagena.
The Biosafety Protocol to the Convention on Biological Diversity is officially known as the Cartagena Protocol on Biosafety. It was adopted in Montreal on January 29, 2000, and entered into force on September 11, 2003.
The protocol is named after Cartagena, Colombia, where an extraordinary meeting of the Conference of the Parties to the Convention on Biological Diversity was held in February 1999 with the aim of finalizing the text of the Protocol. Although the final agreement was reached later in Montreal, the name “Cartagena” was retained. Rio de Janeiro hosted the Earth Summit in 1992 where the Convention on Biological Diversity itself was adopted.

Which of the following statements is NOT correct regarding the travel of sound waves ?

[amp_mcq option1=”Sound waves can travel through water” option2=”Sound waves can travel through air” option3=”Sound waves can travel through steel” option4=”Sound waves can travel through vacuum” correct=”option4″]

Sound waves are mechanical waves, which means they require a medium (like solid, liquid, or gas) to travel. They cannot travel through a vacuum.
– Sound propagates through a medium by causing vibrations in the particles of that medium.
– In a vacuum, there are virtually no particles, so there is no medium for the sound waves to propagate through.
– Options A, B, and C state that sound waves can travel through water (liquid), air (gas), and steel (solid), respectively. These statements are correct as these are all forms of matter that can act as mediums for sound transmission.
– This is why sound cannot be heard in outer space, which is essentially a vacuum.

A liquid is kept in a glass beaker. Which one of the following statements is correct regarding the pressure exerted by the liquid column at the base of the beaker ?

[amp_mcq option1=”The pressure depends on the area of the base of the beaker” option2=”The pressure depends on the height of liquid column” option3=”The pressure does not depend on the density of the liquid” option4=”The pressure neither depends on the area of the base of the beaker nor on the height of liquid column” correct=”option2″]

The pressure exerted by a liquid column at the base of the beaker depends on the height of the liquid column.
– The pressure exerted by a column of liquid at a depth ‘h’ is given by the formula P = ρgh, where:
– P is the pressure
– ρ (rho) is the density of the liquid
– g is the acceleration due to gravity
– h is the height of the liquid column
– The formula P = ρgh shows that liquid pressure depends directly on the density of the liquid, the acceleration due to gravity, and the height (or depth) of the liquid column.
– It is independent of the shape of the container or the area of the base, as long as the height and density are the same (this is known as the hydrostatic paradox).

Vinegar is primarily an aqueous solution of acetic acid, which is also known by its IUPAC name, ethanoic acid.
– Acetic acid (CH₃COOH) is a weak organic acid.
– Culinary vinegar typically contains 5% to 8% acetic acid by volume.
– Acetic acid is produced industrially and also biologically by the fermentation of ethanol by acetic acid bacteria.
– It is widely used in cooking, as a preservative, and for cleaning purposes.

According to the rules governing electron shells, the maximum number of electrons in the N shell (n=4) is 32.
– Electron shells are designated by principal quantum numbers (n), starting from n=1 for the innermost shell (K shell).
– The formula for the maximum number of electrons that can occupy a shell with principal quantum number ‘n’ is 2n².
– For the N shell, n=4.
– Applying the formula 2n² for n=4: Maximum electrons = 2 * (4)² = 2 * 16 = 32.
– The distribution of electrons in shells follows specific rules, filling the lower energy shells first, but the maximum capacity is given by 2n².
