  1. The first industrial revolution was the technological revolution launched from Britain in 1760s, a great revolution in the history of technological development, which created an era of machines instead of manual labor. This is not only a technical reform, but also a profound social change.
  2. The first industrial revolution began with the birth of the machine, and the steam engine was widely used as a symbol. This technological revolution and its related social relations are called the first industrial revolution or industrial revolution.
  3. The first industrial revolution made the factory system replaced by hand workshops and replaced manual labor by machines; from social relations, the industrial revolution disappears the peasant class attached to the way of backward production, and the industrial bourgeoisie and the industrial proletariat grow and grow.
  4. The first industrial revolution greatly strengthened the links between the world, changed the face of the world, finally established the ruling position of the bourgeoisie to the world, took the lead in completing the industrial revolution, and soon became the world's hegemon.

In the periodic table each period begins with the filling of principal quantum number (n). The value ofnfor the sixth period is 6. Forn= 6, azimuthal quantum number (l) can have values of 0, 1, 2, 3, 4. In the 6thperiod, electrons can be filled in only 6s, 4f, 5d,and 6psubshells. Now, 6shas one orbital, 4fhas seven orbitals, 5dhas five orbitals, and 6phas three orbitals. Therefore, there are a total of sixteen (1 + 7 + 5 + 3 = 16) orbitals available. According to Pauli’s exclusion principle, each orbital can accommodate a maximum of 2 electrons. Thus, 16 orbitals can accommodate a maximum of 32 electrons. Hence, the sixth period of the periodic table should have 32 elements.

Mass

Weight

Mass can never be zero. Weight can be zero. As in space if no gravity acts upon an object, its weight becomes zero.
Mass is a scalar quantity. It has magnitude. Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well.
Mass is commonly measured in kilograms and grams. Weight is commonly measured in Newtons.
Mass doesn’t change according to location. Weight varies according to location.
The mass may be measured using an ordinary balance. Weight is measured using a spring balance.

Weight is a quantity in which gravity included while in mass there is no includation of gravity where weight is equal to mass multiply with acceleration due to gravity

Muscles are the structures which in coordination with bones bring about movement in an organ. Muscle contraction is clearly explained by sliding-filament theory. Muscles are made up of 2 types of proteins namely Actin and Myosin filaments.

  •  Muscle starts to contract when it receives information from motor neurons.
  •  Neuromuscular junctions are formed by the junctions between motor neuron and sarcolemma of individual muscle fibre.
  •  As the neural signal reaches neuro-muscular junction, acetyl choline is released at this place.
  •  Acetyl choline causes an action potential in the sarcolemma and releases calcium ions in the sarcoplasm.
  •  Calcium ions bind to the troponin of the actin and bring a change in its structure. This causes a movement in tropomyosin.
  •  This structural change exposes myosin binding sites on actin filaments. Myosin binds to actin forming a cross bridge.
  •  These cross bridges pull the attached actin to the centre of the A band. Z-line is also pulled inwards. This causes shortening of sarcomere which is termed as muscle contraction.
  •  During contraction, I bands are reduced, A bands retain their length. Actin and myosin filaments slide over one another during contraction.
  •  Myosin releases ADP and pi and returns to its original state. New ATP binds to myosin head and the cross bridge is broken.
  •  Myosin head hydrolyses ATP to form a cross bridge.
  •  These events are repeated till calcium ions return into sarcoplasmic reticulum. Calcium ions are released till acetyl choline is present. Acetyl choline is released till the muscle fibre receives signal from motor neurons.

Returns to a factor refers to the change in output when an additional unit of variable input is employed.
The Law of Variable Proportion can be regarded to as 'Returns to a Factor'. According to this law, as more and more of variable factor (labour) is combined with the same quantity of fixed factor (capital), then the total product increases though gradually after a point, the total product becomes smaller and smaller.
The second stage of Law of Variable Proportion is referred as diminishing returns to a factor. Following are the reasons for diminishing returns.

Turbulent flow:- When the velocity of liquid becomes greater than the critical velocity, the particles follow zig-zag path, such a disordered is called turbulent flow. Laminar flow:- The flow in which liquid moves in the form of layers. Streamline flow:- It is an orderly flow of fluid in which all the molecules of the fluid passing through a certain point have same velocity.

Electrons are able to move between electrodes because the chemical reaction is a redox reaction. A redox reaction occurs when a certain substance is oxidized, while another is reduced. During oxidation, the substance loses one or more electrons, and thus becomes positively charged. E° cell = E° cathode - E° anode Where E° value represents the standard reduction potential of the electrode

Because of presence of one sigma and one pi bond in CH2 double bonds and one sigma and two pi bonds in CH triple bonds. We can whole conclude that pi bonds are the weakest bonds and it plays a major in more reactiveness and less reactiveness as CH2 double bond and CH triple bonds .
