A thermite reaction is basically iron oxide (rust) reacting with aluminum to produce molten iron. The products are aluminium oxide, elemental iron, and a large amount of heat. The reactants are commonly or thermite mixture is aluminum powder and iron oxide (rust) powder. When the mixture is heated, it starts reacting as the aluminum is more reactive than the iron and aluminium forms stronger and stable bonds with oxygen than iron.

The thermite reaction is an exothermic reaction between the metal and metal oxide.

We are familiar with air current and water current. We know that flowingwater constitute water current in rivers. Similarly, if the electric chargeflows through a conductor (for example, through a metallic wire), wesay that there is an electric current in the conductor. In a torch, weknow that the cells (or a battery, when placed in proper order) provideflow of charges or an electric current through the torch bulb to glow. Wehave also seen that the torch gives light only when its switch is on. Whatdoes a switch do? A switch makes a conducting link between the cell andthe bulb. A continuous and closed path of an electric current is called anelectric circuit. Now, if the circuit is broken anywhere (or the switch of thetorch is turned off), the current stops flowing and the bulb does not glow.How do we express electric current? Electric current is expressed bythe amount of charge flowing through a particular area in unit time. Inother words, it is the rate of flow of electric charges. In circuits usingmetallic wires, electrons constitute the flow of charges. However, electronswere not known at the time when the phenomenon of electricity was firstobserved. So, electric current was considered to be the flow of positivecharges and the direction of flow of positive charges was taken to be thedirection of electric current. Conventionally, in an electric circuit thedirection of electric current is taken as opposite to the direction of theflow of electrons, which are negative charges.

The free electrons flow inside it

Electric Current: The flow of electric charge is known as electric current. Electric current is carried by moving electrons through a conductor. By convention, electric current flows in opposite direction to the movement of electrons.

In a democratic government the citizens of the country have right to select their representatives while in any other form of government citizens doesn't have any right to select their representatives. In a democratic country people have several rights such as right to speech, right against exploitation, right to freedom etc. While in any other form of government people doesn't have these rights. In a democratic country the representatives are changed after a fixed year but in other forms of government the representatives are not changed a fixed time. The most important thing in a democratic government is that people have the right to vote but in any other forms people doesn't have right to vote. Democracy is a government which us for the people, by the people and of the people, but no any other form of government contains these features. That's why it is said that democracy is the best form of government... Hope it helps you..

(i) Economic growth depends on the size of the population of a country. We can see that in our country economic growth cannot cope with the problem of a bursting population of more than a billion people.
(ii) It also depends on the global situation and cooperation from other countries. All developing countries need help of the rich and developed nations to grow.
(iii) The policies of the government also affect economic growth of country.

Increase in employment Increases GDP of country Growth of health and education system

Merits of dictatorship:
1) Establishment of a strong Government:
(2) Stable and efficient Government:
(3) Economic Prosperity:
(4) Social Reforms:
(5) Facing the crisis boldly:
Demerits of dictatorship:
1) Curtailment of the rights and liberties of the people:
2) Establishment of Absolute Government:
3) Dictators lead the country to war:
(4) Dictators do not leave behind capable successors:
(5) No importance of individual:

(i) In a democracy, elections are held at regular intervals and are fair and free.
(ii) A democracy has a multi-party system and elections are held on the basis of universal adult franchise.
(iii) Freedom of speech, expression and thought is another feature of democracy. The media also helps in building a sound public opinion.
(iv) Democracy gives to its citizens a sound political system based on social equality.
(v) Another feature of a democracy is a strong opposition which keeps in check, the ruling party or the government.
(vi) Besides these, we also know how in a democracy, the dignity of the individual is recognised and one can correct one’s mistakes in a democracy and avoid conflicts.

(i) The wealth and means are accumulated in hands of a few people and their share in the total income of the country has been increasing.
(ii) However, the people at the bottom of society find it difficult to meet even their basic needs of life such as food, clothing, house, education and health.Not only that, their incomes have been declining.
(iii) The deprived people are a large ratio of voters and no party will like to lose their votes.
(iv) Yet democratically elected governments do not appear to be attentive to the cause of the poor. Thus democracies do not appear to be very successful in reducing economic inequalities.

Following are the points on basis of which a nation can claim to follow Democratic Governments:

1. Presence of Fundamental rights: by giving the fundamental rights the government delivers freedom of expression, freedom of speech to every citizen. Moreover, democracy allows the media to work freely.  

2. Periodic elections: periodical elections are must in the democratic countries as it ensures the rule of people. It is important to change the government peacefully.  

3. Independent Judiciary: it is necessary to have a sovereign judiciary which serves as the custodian of our fundamental rights.

Democracies are based on political equality. All individuals have equal right in electing representatives. Parallel to the process of bringing individuals into the political arena on an equal footing, find growing economic inequalities. A few number of rich enjoy a highly disproportionate share of wealth and incomes. Not only that, their share in the total income of the country has been increasing. Those at the bottom of the society have very little to depend
upon. Their incomes have been declining and sometimes they find it difficult to meet their basic needs of life such as food, clothing, house, education and health.

• A democratic government is elected by people and the head of the country is elected for a fixed period of time. The head of the state in a non-democratic government is not the representative of the people (as he is not elected by the people) and may continue to remain in power for unspecified period of time.
• Democracy is based on the idea of deliberation and negotiation. As a result, democratic political systems take time in executing decisions. In a non-democratic government, the leaders need not bother themselves with public opinion, and hence, decision making process in such systems is quicker.
• In a democracy, decisions of the Government are acceptable to the people and are more effective in redressal of the public’s concerns. Dictators can take decisions that are not acceptable to the public at large.
• While a democratic government is a legitimate, responsible and accountable to the people, a non-democratic government is not accountable to people.

The story ‘The Hack Driver’ is the story of a hack driver called Oliver Lutkins. He lived at New Mullion. He was an important witness in a court case. The law firm wrote many letters to him but he did not appear before the court. At last, the firm sent a young lawyer to New Mullion to issue summons to Lutkins. The junior assistant clerk did not recognise Lutkins. Lutkins met him at the station. He took the assistant clerk all over the town in search of Lutkins although he himself was Lutkins. He could not serve the summons to Lutkins. He had to return back to the city. But the owner of the legal firm sent him back to New Mullion. He could serve the summons to Lutkins this time`The Hack Driver’ is the story of a very cunning manipulator Bill (Oliver Lutkins). It also shows that appearances are often deceptive. Once, the narrator, a junior clerk in a law firm, had to go to New Mullion to serve a summon to Oliver Lutkins. There he met Bill (Oliver Lutkins), the hack driver. When the narrator asked about Oliver Lutkins, Bill took him to Fritz who replied that Oliver had been there a little while ago. Bill, who was Oliver Lutkins himself, made a plan to befool the narrator. In a very friendly but subtle way, Bill manipulated the tour, taking the lawyer around the village. He arranged meetings with Fritz, Gustaf’s shop owner, a barber etc. Then Bill took him to Oliver Lutkins’ mother who was a terrible, huge woman who threatened to beat them. At last, he returned disappointed. He couldn’t trace Oliver Lutkins. His boss rebuked him badly and asked him to go back to New Mullion with a person who knew Lutkins. When they reached there, he found Bill and Lutkins’ mother together. The man recognised Lutkins. He told that Bill no one but Lutkins himself.

It can be said that the lawyer was gullible. He could have avoided being taken for a ride if he had noticed what the hack driver was doing.The lawyer could have taken control of the proceedings by asking the hack driver to step aside and by doing his work himself.

Factors the number,

LCM is the least common multiple,

Therefore, LCM of 30240 and 29700 using prime factorisation method is 1663200.

Let
P(4, m) = (x, y)
A(2, 3) = (x1, y1)
B(6, -3) = (x2, y2)
By using section formula in this points, we get.
Let the ratio in which P divide the line segment A and B be = k:1
Therefore,
x = kx₂ + x₁(1)/k + 1
=> 4 = 6k + 2 /k + 1
=> 4k + 4 = 6k + 2
=> 2k = 2
=.> k = 1
So, the ratio = 1:1
Now,
y = k(y₂) + 1(y₁) / k + 1
=> m = -3 + 3 /1 + 1
=> m = 0/2
=> m = 0.

I think two types

There are no major difference between total resistance and equivalent resistance

The equivalent resistance is where the total resistance connected either in parallel or in series. Electrical resistance shows that how much energy will be required when we move the charges i.e. current through the circuit. If we need lots of energy, then the resistance necessary should also be high. The equivalent resistance of a network is the single resistor which can replace the entire network in such a way that for a certain applied voltage as V we will get the same current as I.

Defection refers to changing part allegiance from the party on which s person got elected to a different party.
The constitution was amended to prevent MLAs and MPs from changing parties. This was done by these representatives in order to become ministers or for cash rewards.
Now the law says that if any MLA or MP indulges in defection, he or she will lose the seat in the legislature.thsi new law has brought defection down but this has also made some MPs and MLAs to accept whatever the party decides.
