UPSC Civil Services GK Questions 2026

The correct answer is B, pascal second, equal to a newton second per square metre, which follows from Newton's law of viscosity, where the shearing stress in pascals is divided by the velocity gradient in reciprocal seconds.

Pascal's law says that pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid and to the walls of the vessel, so a modest push on the brake pedal creates a pressure in the brake fluid that is passed to the wider pistons at every…

In a capillary tube the height of rise is directly proportional to the surface tension of the liquid and inversely proportional to its density and the radius of the tube.

In such a fluid the shearing stress is directly proportional to the rate of shear, so the coefficient of viscosity, which measures the resistance to deformation, keeps the same value whatever the stress applied; water, air, petrol and thin oils behave in this way.

The upthrust on a body is the resultant of the pressure forces of the fluid around it, and that resultant acts through the centre of gravity of the fluid the body has pushed aside, which is why the point is called the centre of buoyancy.

A floating body displaces its own weight of fluid, so the fraction of its volume that lies below the surface equals the ratio of its density to the density of the fluid, here 920 divided by 1000, which is 0.92.

By Archimedes' principle the upthrust on a body equals the weight of the fluid it displaces, and that weight is the volume of the body actually immersed multiplied by the density of the fluid and by the acceleration due to gravity.

The Vice-President traced the institution’s journey from a Sanskrit Vidyapeetha to a Central University and said the time had come for it to fulfil its founder’s vision by establishing itself as a leading international centre for Sanskrit studies.

The mission is meant to preserve and document India’s manuscript heritage and to bring it within reach of readers in the country and abroad, and the Vice-President cited it while asking teachers and students to seek out unpublished Sanskrit manuscripts, preserve them, edit them critically and publish them.

The Vice-President praised the university for securing it and for carrying out research across the many domains of the Indian knowledge tradition, and he urged the institution to go further and become a leading international centre of excellence for Sanskrit studies.

The Union Minister of that ministry, Dr Mansukh Mandaviya, announced it with the remark that Yuva Shakti is the strength of a developed India.

The copy handed over is hardbound and carries the signature of the Minister of State for Youth Affairs and Sports.

At that count the portal carries the achiever in a dedicated Digital Hall of Fame, showing the name, the MY Bharat identity number, a photograph and a short profile taken from the public profile.

The board meeting is convened by the Indian Coast Guard under the chairmanship of its Director General, Paramesh Sivamani, and takes up national preparedness for rescue at sea, the management of distress alerts and faster movement of rescue assets through technology and coordination between agencies.

The number of observers is slightly larger than the number of countries because some nations have sent more than one representative, and the Ministry of Defence treats this international presence as a highlight of the drill, since it points to shared rescue protocols and the ability of different navies and…

The exercise is being held off the Paradip coast of Odisha and is inaugurated by the Minister of State for Defence, with the search and rescue demonstration at sea following a day later.

The two armies first climbed together on Mt Aconcagua at 6,962 metres in Mendoza, Argentina, in January 2025, then on Mt Kun at 7,077 metres in the Suru valley of Ladakh in August 2025, and the Uttarakhand outing of this year was therefore the third in the series.

He headed the party of 35 climbers, of whom 25 belonged to the Indian Army and 10 to the Argentine Army, and the group was flagged off from the Manekshaw Centre in New Delhi on 21 August 2026.

Mt Kamet stands in the Chamoli district of Uttarakhand and is the third-highest mountain within India, which places exactly those two peaks above it.

The vehicle set up to build and run the zone gives the Madhya Pradesh government the controlling share and the Department of Telecommunications the rest, which makes the project an example of a Centre-state partnership where the state leads on the ground while the Centre funds the first phase.
