The Green Revolution, or the Third Agricultural Revolution, is the set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production in parts of the world, beginning most markedly in the late 1960s.[1] The initiatives resulted in the adoption of new technologies, including high-yielding varieties (HYVs) of cereals, especially dwarf wheat and rice. It was associated with chemical fertilizers, agrochemicals, and controlled water-supply (usually involving irrigation) and newer methods of cultivation, including mechanization. All of these together were seen as a 'package of practices' to supersede 'traditional' technology and to be adopted as a whole.[2] The key elements of the revolution include: 1) Use of the latest technological and capital inputs, 2) adoption of modern scientific methods of farming, 3) use of high yielding varieties of seeds, 4) proper use of chemical fertilizers, 5) consolidation of land holdings.

Law Incorporation [45]

Answer: 4500 metres

Explanation:

Echo is a reflection of sound wave. It is the sound heard after it has been reflected off the surface of a wall or cliff.

Time = 6 seconds

Speed of sound in water = 1500m/s

distance =?

From the relationship ;

Speed = distance / time

Distance = speed * time

Distance = 1500 * 6 = 9000 metres

Distance here represents the total distance traveled by the pulse that is distance to the seafloor and back to the surface.

Therefore the depth of the water is given by;

Depth = distance / 2

Depth = 9000 / 2 = 4500metres.
