When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. Magnetic force obeys an inverse square law with distance. ... If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. (F/4) If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value.

The tidal force acting on an astronomical body, such as the Earth, is directly proportional to the diameter of that astronomical body and inversely proportional to the cube of the distance from another body producing a gravitational attraction, such as the Moon or the Sun.
The formula for the force of attraction is articulated as,
G is the gravitational constant (6.67 × 10-11 Nm2/kg2), the mass of object 1 is m1 , the mass of object 2 is m2 , the distance between two objects is d.

A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. A theory does not change into a scientific law with the accumulation of new or better evidence. A theory will always remain a theory; a law will always remain a law. Both theories and laws could potentially be falsified by countervailing evidence. Theories and laws are also distinct from hypotheses.

The production of electricity from magnetism is known as electromagnetic induction.
Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.
Let us move the wire AB upward rapidly between the poles of the horseshoe magnet. When the wire is moved up, there is deflection in the galvanometer pointer shows a current is produced in the wire AB momentarily which causes the deflection in galvanometer.

Law of floatation is a special condition of Archimedes' Principle which states that the weight of a floating body is equal to the weight of the displaced liquid. Legend says that Archimedes discovered the principle of displacement while stepping into a full bath. He realized that the water that ran over equaled in volume the submerged part of his body. Through further experiments, he deduced the above mentioned Archimedes' principle.

Falling drop of a liquid is always spherical in shape due to surface tension. The inward forces on the surface molecules of the liquid droplet tend to cause the surface to volume ratio as small as possible. Liquid drops are spherical because of surface tension. Hence when small amount of liquid is separated from rest in the form of drop, the whole amount of liquid gets in the most energy efficient shape i.e. sphere due to the attraction of atoms/molecules, which we call surface tension.

After the failure of non-cooperation-khilafat movement, muslims felt alienated from the congress. The reason was, from the mid 1920s, congress started associating itself with Hindu religious nationalist groups like the Hindu Mahasabha.
There were religious processions organised by each community with militant fervour provoking Hindu-Muslim communal clashes and riots.
Although there were efforts by the Congress and Muslim league to renegotiate an alliance in 1927, but as Jinnah had put up the demand for seperate electorates, the hope for resolving the issue at the All Parties Conference in 1928 shattered when M.R.Jayakar of Hindu Mahasabha refused to compromise.
When the Civil Disobedience movement started there was an atmosphere of distrust b/w the communities. Muslim leaders feared that the identity of muslims will be lost under the domination of a Hindu majority.

The angle of deviation is the angle between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another. The emergent ray is bent at an angle with the direction of the incident ray. This angle is called the angle of deviation. The phenomenon of splitting of white light into its constituent seven colours on passing through a glass prism is called dispersion of light. The smallest angle through which light is bent by an optical element or system. In a prism, the angle of deviation is a minimum if the incident and exiting rays form equal angles with the prism faces. The angle is important relative to prism spectroscopes because it can be easily determined.

The Human Development Index HDI is defined as the composite statistics used to rank countries by levels of human development. The HDI is a measure of health, education and income. It measures the average achievements in a country in these three basic dimensions of human development, calculated into an index.
Health - Life expectancy at birth
Education - expected years schooling for school-age children and average years of schooling in the adult population
Income - measured by Gross National Income (GNI) per capita.

An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current. The major difference between the ammeter and the voltmeter is that the ammeter measures the flow of current, whereas the voltmeter measures the emf or voltage across any two points of the electrical circuit. For example, an analog voltmeter with a ±3% accuracy is set to the 0 to 100-V range. Based on this accuracy, its pointer can be 3 volts (100 V x 0.03 = 3 V) below or above the true reading. If the true measured value is, for example, 90.0 V, the meter might read between 87 V and 93 V or ± 3.3% of reading.

The caricaturists is trying to depict the true nature of conservative monarchies of the 19th century Europe, which did not allow the ideas of liberalism and individual freedom to flourish. In the picture the club has thinkers but they do not have power to express their thought. This is the right way to depict that the people did not have the freedom of speech or freedom of press.

Ernst Renan was a French philosopher, who outlined the attributes of a nation which are as follows (t) A nation is not formed by a common language, race, religion or territory.
(ii) To form a nation, social capital, common glories and deeds of the past and common will are necessary. A nation is the culmination of a long past of endeavours, sacrifice and devotion.
(iii) Nation is a large-scale solidarity, its existence is a daily plebiscite and ts inhabitants have the right to be consulted.
(iv) The existence of a nation is not only a good thing, but also a necessity.
(v) A nation has never any real interest in annexing or holding on to a country against its will.
Nations are important because existence of the nation is a guarantee of liberty. Liberty would be lost if the world had only one law and only one master.

The ratio of potential difference and current is known as Resistance.....
I = V/R.
R= V/I.
Where l is current, V is potential difference and R is resistance.
