Child labour should be eliminated because it takes away from the child his childhood and the prospect of elementary education. Moreover, since the child labourers are cheap, and consequently engaged in hazardous and dangerous employment, they are often vulnerable to mental and physical illness. Entering the workforce too early diminishes a child's lifetime earning potential. Child laborers have very limited ability to take advantage of educational opportunities that would help them receive better-paying jobs as adults.

Cropping pattern refers to the proportion of land under cultivation of different crops at different points of time. This indicates the time and arrangement of crops in a particular land area. Any change in the cropping pattern would cause:
-
change in the proportion of land under different crops
-
change in space sequence and time of crops
In India, the cropping pattern is determined by rainfall, temperature, climate, technology and soil type.

An emf induced by the motion of the conductor across the magnetic field is a motional electromotive force. The equation is given by E = -vLB. This equation is true as long as the velocity, field, and length are mutually perpendicular. The minus sign associated with the Lenz’s law.
Let us take a rectangular coil, a metal rod of length L, moving with velocity V, through a magnetic field B. There is a magnetic field at some location.
Length, velocity and magnetic field should always be at a right angle with each other. The direction of the magnetic field is going inside. Assume the metal rod is frictionless that means there is no loss of energy due to friction and we apply a uniform magnetic field. The conductor rod is moved with a constant velocity and placed in the magnetic field.

For tea production -
Tea is a favorite drink all over the world today.
India is the largest producer and exporter of tea in the world. The ideal climatic conditions for the production and growing of tea are as follows:
Temperature: 21°C to 29°C is ideal for the production of tea. High temperature is required in summer. The lowest temperature for the growth of tea is 16°C.Rainfall: 150-250 cm of rainfall is required for tea cultivation.Soil: Tea shrubs require fertile mountain soil mixed with lime and iron. The soil should be rich in humus.Land: Tea cultivation needs well drained land. Stagnation of water is not good for tea plants. Heavy rainfall but no stagnancy of water, such mountain slopes are good for tea cultivation.
A huge number of women labors along with plywood, packing box industry, factory sheds etc., are required for tea cultivation.
And for coffee production -
Coffee is the second most popular beverage of India. Its cultivation is confined in South India. Favorable Geographical Conditions for the Cultivation: Coffee is grown on the tropical highlands. Coffee is a typical highland crop of the Tropics. It requires temperature between 16 degree C and 28 degree C all the year round. It is sensitive to cold and frost. Direct sunrays are injurious to the plant; it is often grown in the shades of other trees. The coffee plant needs a rainfall ranging between 125 cm and 200 cm. The rainfall should be well distributed throughout the year. Hilly slopes are suitable for coffee plantation; because, the land can be kept free from water logging. In fact, the mountain slopes at elevations varying from 500-1800 meters in the tropical highlands are the best for its plantation. The coffee plant needs deep loamy soil formed from weathered lava. Coffee soils in India belong to red and later tic soils. They are rich in iron and organic matter. Coffee cultivation needs plenty of labor for planting, seeding transplanting, plucking the coffee cherries, and processing of coffee in the factory. In India, most of the coffee grown, belongs to the Arabic or the Roberta verities. T

Chlorobenzene is less reactive towards nucleophilic substitution reaction because of the following reasons:
(1) Resonance effect: The electron pair on chlorine atom is in conjugation with the 
electrons of the benzene ring which results in the following resonance structures:
This results in delocalization of the electrons of C - Cl bond and a partial double bond character develops in the bond, which makes it difficult for the Nucleophile to cleave the C - Cl bond.
(2) Polarity of the C-Cl bond: The sp2 hybridized carbon atom involved in C-Cl bond in chlorobenzene is more electronegative than the sp3 hybrid carbon atom in alkyl halide. Therefore, this sp2 hybridised carbon atom has less tendency to release electrons to the Cl atom. Thus, lower the polarity of C-Cl, lesser is the reactivity.

Viruses are non-cellular, microscopic infectious agents that can only replicate inside a host cell. From a biological perspective, viruses cannot be classified either a living organism or non-living. This is due to the fact that they possess certain defining characteristic features of living organisms and non-living entities.
