1. THE CLERGY

• Church was a powerful institution. The Pope, the head of the Catholic Church, lived in Rome. Bishops were religious nobility.
• The church played a major role in influencing the Medieval European society.
• They collected the tithe, a tax from the peasants.
• Church ceremonies copied several formal feudal customs.
• Some Christians chose to live in isolation in abbeys. (‘Abbey’ is derived from the Syriac abba, meaning father. An abbey was governed by an abbot or an abbess)

2. NOBILITY

• The word ‘Feudalism’ is derived from the German word ‘feud’ which means ‘a piece of land’. Feudalism was a division of society that initially developed in medieval France, then in England and southern Italy.
• It was a kind of agricultural production relationship between lords and peasants.
• The nobility had a privileged role in the social process with absolute control over his land. They raised troops that were called ‘Feudal Levies’. The King of France was linked to his people through the system of ‘vassalage’. The King was accepted as Seigneur, i.e. lord. The nobility lived in manor houses.
• The cavalry and peasant soldiers were called knights. Minstrels and bards toured France, singing tales of brave kings and knights.

3. THE PEASANTRY

• Peasants and Serfs were two kinds of cultivators in medieval Europe.
• Free peasants laboured for cultivating the lord’s fields to provide labour rent. They paid a direct tax, called taille, to the king. European monarchs were called New Monarchs.

The Anglo-Saxons had a Great Council, which the king consulted before imposing any tax. This developed into the Parliament, with the House of Lords (its members – the lords and the clergy), and the House of Commons. The English monarch, Charles the First, ruled England from 1629 till 1640 without calling the Parliament.

The number of atoms present in 100 amu of helium is 25 atoms.

To find:

Number of atoms = ?

Solution:

The number of atoms present in 100 amu of helium is to be calculated by using simple unitary method knowing that the a.m.u. is the atomic mass unit which itself represent the mass.

So thereby, we need to know the "mass of one atom" and that can be divided to know the "number of atoms".

Therefore,

The "mass of one atom" of helium is known to be 4 a.m.u.

Thereby,

Work energy theorem states that the change in kinetic energy of an object is equal to the net work done on it by the net force.

Let us suppose that a body is initially at rest and a force is applied on the body to displace it through  along the direction of the force. Then, small amount of work done is given by

Also, according to Newton's second law of motion, we have

where a is acceleration produced (in the direction of force) on applying the force. Therefore, 

Now, work done by the force in order to increase its velocity from u (initial velocity) to v (final velocity) is given by

Hence, work done on a body by a force is equal to the change in its kinetic energy.

The respiratory zone includes the structures of the lung that are directly involved in gas exchange: the terminal bronchioles and alveoli. ... This is a blood-air barrier through which gas exchange occurs by simple diffusion. In the mediastinum, at the level of the fifth thoracic vertebra, the trachea divides into the right and left primary bronchi. The bronchi branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli.

. Industrialisation changed the form of urbanisation in the modern period.
. The early industrial cities of Britain such as Leeds and Manchester attracted large number of migrants to the textile mills set up in the late 18th century.
. The city of London was a powerful magnet for migrant populations, even though it did not have large factories.
. London was a colossal city and its population expanded four-fold from 1 million to 4 million; as the Industrial Revolution attracted more and more people.

Discovering Tut - the saga continues is a historical description of the journey in finding out the truth behind death of Tutankhamun - the ruler of Egypt.
In this essay, Tutankhamun comes across as a pious man who restarted the worship of Egyptian God Amun.
He was also fond of ancient Egyptian culture and established the traditional ways once again.

Wellness : is the ability to live fully with vitality and meaning. It is dynamic & multi dimensional. Wellness incorporates physical emotional, spiritual, intellectual, inter personal, social and environmental dimensions.

Components of wellness: Physical Activity: It makes the person fit and active. It improves various system of body and improves our health. It also improves our growth and development.

Balanced Emotional life: Wellness requires a balanced emotional life and release of emotions. Moreover it should be under control.

Intellectual Attitude: Wellness requires positive intellectual attitude. It improves our behavior, intelligence, alertness, futuristic and insight thinking.

Spiritual wellness: It makes the person ethically good, morally good, peaceful more- over guides the value of life.

Occupational wellness: It makes the person to be hard worker and earn the livelihood with honesty. It helps to achieve the balance of work and leisure and gives satisfaction.

The unit of coefficient of viscosity can be understood by defining the coefficient of viscosity.

Following is the unit of coefficient of viscosity in different systems:

• SI unit: Ns.m^-2
• CGS unit: poise

Viscosity is a measure of a fluid's resistance to flow.

It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. The SI unit for dynamic viscosity η is the Pascal-second (Pa-s), which corresponds to the force (N) per unit area (m2) divided by the rate of shear (s-1).

The perpendicular axis theorem states that the moment of inertia of a planar lamina about an axis perpendicular to the plane of the lamina is equal to the sum of the moments of inertia of the lamina about the two axes at right angles to each other, in its own plane intersecting each other at the point where the perpendicular axis passes through it.

The value of 'g' that is gravity is greater at the poles because the gravitational pull is maximum at the poles and decreases as it comes down toward the equator. Because the force due to gravitational attraction between two bodies (the Earth and the object being weighed) varies inversely with the square of the distance between them, an object at the Equator experiences a weaker gravitational pull than an object at the poles.
