Statements 1, 3 and 4 describe Shankardeva correctly; statement 2 is wrong because Gaudiya Vaishnavism was founded by Chaitanya Mahaprabhu of Bengal.

Inside a long current-carrying solenoid the magnetic field has the same strength and direction at every point, shown by parallel, evenly spaced field lines.

The standard account of Mughal-era agriculture records that maize came into India via Africa and Spain, and by the seventeenth century it was listed among the major crops of western India.

Work is W = F × d × cos θ, and when the angle θ between force and displacement is 90°, cos 90° = 0, so the work done is zero.

Panchsheel says nothing about nuclear weapons; its five principles concern sovereignty, non-aggression, non-interference, equality and peaceful coexistence.

Planck's constant has the dimensions [ML²T⁻¹], exactly those of angular momentum. From E = hf, h = E / f. Energy has dimensions [ML²T⁻²] and frequency has [T⁻¹], so h has [ML²T⁻²] ÷ [T⁻¹] = [ML²T⁻¹], with the SI unit joule-second.

Most members of the Rajya Sabha are elected indirectly by the elected members of the State Legislative Assemblies through proportional representation by means of the single transferable vote.

A telescope's objective must gather as much light as possible from a distant object and form a large image, so it is both wide and of long focal length.

X-rays have wavelengths from about 0.01 nm to 10 nm, so 1 nm lies well inside the X-ray band. In the electromagnetic spectrum, wavelength decreases from radio waves through microwaves, infrared, visible light and ultraviolet to X-rays and gamma rays.

The 73rd Amendment gave panchayats constitutional status. The Constitution (Seventy-third Amendment) Act, 1992 came into force on 24 April 1993, the date now marked as National Panchayati Raj Day.

One pascal is defined as a force of one newton acting on an area of one square metre. Pressure is force per unit area, and its SI unit, named after the French scientist Blaise Pascal, is the pascal (Pa): 1 Pa = 1 N/m².

Vinoba Bhave asked every landowner to treat him as a son and give him a son's share, one-sixth of the land, for the landless.

Gravity is a conservative force, so the work it does never depends on the path. The work done by gravity on a body of mass m is mgh, where h is the vertical height between the start and the end.

This law let the government imprison people suspected of political activity without trial for up to two years. Officially the Anarchical and Revolutionary Crimes Act, it was passed in March 1919 on the advice of the Sedition Committee headed by Justice S.A.T.

One kelvin and one degree Celsius are the same size, so a rise of 30 K is also a rise of 30°C. The Kelvin and Celsius scales differ only in their starting point: T(K) = t(°C) + 273 (more exactly 273.15).

The shalabhanjika, a woman holding the branch of a tree, comes from popular fertility beliefs, not from Buddhist teaching. The gateways of the Great Stupa at Sanchi carry rich carvings.

Force depends on how fast momentum changes, not on the momentum itself. Newton's second law states that the rate of change of momentum of a body is proportional to the net force on it and takes place in the direction of the force.

The Vajji mahajanapada was a gana-sangha, ruled by an assembly of clan chiefs rather than by a single king. Of the sixteen mahajanapadas named in Buddhist texts such as the Anguttara Nikaya, most were monarchies, but Vajji and Malla were ganas or sanghas.

One parsec equals about 2,06,265 astronomical units, which rounds to 2 × 10⁵ A.U.

Most Harappan seals were carved from steatite, a soft soapstone that hardens when fired. Steatite is easy to cut, so craftsmen could carve fine animal figures and signs of the Harappan script on it.
