In uniform circular motion the body covers equal arcs in equal times, so its speed, a scalar, does not change; its kinetic energy and its angular velocity are constant too.

When a body rolls, the surfaces in contact change continuously and the irregularities have no time to interlock deeply, so rolling friction is very much smaller than sliding friction; this single fact is the reason the wheel was invented and the reason a ball bearing is fitted wherever a shaft…

The coefficient of friction is the ratio of the limiting or kinetic frictional force to the normal reaction, and since both are forces the ratio is a pure number; the same reasoning applies to other ratios such as the refractive index and relative density.

Friction is defined as the force that opposes the relative motion, or the tendency of relative motion, between two surfaces in contact; it acts along the surfaces and always against the direction of motion.

. The Act of 1919 did not make the Central Executive responsible to the Legislature; the Governor-General and his Executive Council stayed answerable only to the British Parliament.

. Under MPLADS an MP only recommends works; the district authority sanctions, executes and completes them.

The Moderates never demanded universal adult franchise; they asked only for a larger share for educated Indians in the legislative councils.

Annie Besant founded the Central Hindu College (with its school) at Benaras in 1898, and it later became the nucleus of Banaras Hindu University.

The Occupational Safety, Health and Working Conditions Code, 2020 brought together the Factories Act, 1948, the Plantations Labour Act, 1951 and other laws on safety and working conditions.

Only statement 3 is correct: the acid must be added slowly to water, and dilution lowers the concentration of hydronium ions per unit volume.

. The National Recruitment Agency was created to hold a Common Eligibility Test to shortlist candidates for Group B and Group C (non-technical) posts of the Central Government.

Gandhiji regarded Gopal Krishna Gokhale as his political guru, his Rajya Guru. Gandhi first met Gokhale in 1896 and they grew close when Gokhale visited South Africa in 1912.

Planck's constant has the same dimensions as angular momentum, [M L² T⁻¹].

Biogas is mainly methane and carbon dioxide. Biogas is produced when bacteria break down animal dung, crop waste and kitchen waste in the absence of oxygen, a process called anaerobic digestion.

Punjab has the highest share of Scheduled Castes in its population among the States, about 31.9 per cent in Census 2011.

Pradhan Mantri Gram Sadak Yojana, launched on 25 December 2000, is the oldest of the four schemes. PMGSY was started to give all-weather road connectivity to unconnected rural habitations, and it is fully centrally sponsored.

The Prati Sarkar, a parallel government of the Quit India period, was set up in Satara district of Maharashtra. During the Quit India Movement that began in August 1942, people in some areas threw off British authority and ran their own governments.

The Indian federation was not formed by an agreement among the States, so "the federating units consented to form a union" is not a feature of Indian federalism.

Goa became the first State in India where every rural household had a functional tap water connection.

A soda-acid extinguisher uses sodium hydrogen carbonate (baking soda) solution and sulphuric acid, which react to release carbon dioxide. In this extinguisher the sulphuric acid is kept in a separate container inside a cylinder filled with sodium hydrogen carbonate solution.
