The chemical reaction needs to be balanced as, it is only rearrangement of atoms.
Atoms are neither created nor destroyed during a chemical reaction.
Therefore, the chemical reaction needs to be balanced to follow the law of conservation of mass.

The magnetic field produced due to current flowing in a coil or a solenoid can be used to magnetise a material like soft iron temporarily. The insulated copper wire is wrapped on a soft iron piece. When current is passed through the coil using a battery and a key the iron piece behaves like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet.

The political conditions of Europe as follows : (i) The first half of the nineteenth century saw an enormous increase in population all over Europe.
(ii) In most countries, there were more job seekers than employment. Population from rural areas migrated to the cities to live in overcrowded slums.
(iii) Small producers in towns were often faced with stiff competition from imports of cheap machine made goods from England, where industrialisation was more advanced than on the continent.
(iv) In these regions of Europe where the aristocracy still enjoyed power, peasants struggled under the burden of feudal dues and obligations.
(v) The rise of food prices or a year of bad harvest led to widespread pauperism in town and country

[ i ] sinA in terms of cotA :
sinA = 1 / cosecA
We know that: cosec²A = 1 + cot²A
sinA = 1 / √1 + cot²A
[ ii ] secA in terms of cotA :
We know that: 1 + tan²A = sec²A
secA = 1 + tan²A
secA = 1 + 1 / cot²A
secA = √(cot²A + 1 ) /cotA
[ iii ] tanA in terms of cotA :
tanA = 1 / cotA

A reflex arc is a neural pathway that controls an action reflex. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex action occurs. There are two types of reflex arc: autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles).
A reflex action is an automatic and inborn response to a stimulus that involves a nerve impulse passing from a sensory nerve cell to a muscle or gland without reaching the level of consciousness. Simple reflexes include sucking, swallowing, blinking, scratching, and the knee jerk. Most reflexes consist of complex patterns of many unconsciously coordinated muscular actions that form the basis of much instinctive behavior in animals. Examples include walking, standing, the cat's righting reflex, and basic sexual acts.

x²-3√5x+10=0
Splitting the middle term, we get
=> x²-2√5x-√5x+10=0
=> x²-2√5x-√5x+2×5=0
=> x²-2√5x+√5x +2×√5×√5=0
=> x(x-2√5)-√5(x-2√5)=0
=> (x-2√5)(x-√5)=0
=> x-2√5 =0 Or x-√5 = 0
=> x = 2√5 Or x = √5
Therefore,
Roots of given Quadratic equation are:
2√5 Or √5

The Vedas are a collection of hymns and other ancient religious texts written in India between about 1500 and 1000 BCE. They are divided into four groups, Rigveda, Yajurveda, Samaveda, and Atharvaveda.
Rigveda: It is a collection of 1,028 Vedic Sanskrit hymns and 10,600 verses in all, organized into ten books.
Yajurveda: It consists of archaic prose mantras and also in part of verses borrowed from the Rig-Veda.
Samveda: It is the "Veda of chants" or "Knowledge of melodies". The name of this Veda is from the Sanskrit word saman which means a metrical hymn or song of praise.
Atharvaveda: It contains first-class poetry coming from visionary poets, much of it being a glorification of the curative powers of herbs and waters.

Decomposition is a type of chemical reaction. It is defined as the reaction in which a single compound splits into two or more simple substances under suitable conditions. It is just the opposite of the combination reaction.
For example: The digestion of food in our body is accompanied by a number of decomposition reactions. The major constituents of our food such as carbohydrates, fats, proteins, etc.,decompose to form a number of simpler substances. These substances further react, releasing large amounts of energy, which keeps our body working.
