Explanation:
Given :
Force,
.
Force is acting at point A( 2 m, 3 m ) and B( 3 m, 5 m )
To Find :
The work done by force F .
Solution :
Displacement vector between point A and B is :
![\vec{d} = (3-2)\hat{i} + (5-3)\hat{j}\\\\\vec{d} = \hat{i} + 2\hat{j}](https://tex.z-dn.net/?f=%5Cvec%7Bd%7D%20%3D%20%283-2%29%5Chat%7Bi%7D%20%2B%20%285-3%29%5Chat%7Bj%7D%5C%5C%5C%5C%5Cvec%7Bd%7D%20%3D%20%5Chat%7Bi%7D%20%2B%202%5Chat%7Bj%7D)
Now, we know work done is given by :
![W = \vec{F}.\vec{d}\\\\W= (2\hat{i} + 5\hat{j}).(\hat{i}+\hat{2j})\\\\W = (2\times 1) +( 5\times 2) \ kJ\\\\W = 12 \ kJ](https://tex.z-dn.net/?f=W%20%3D%20%5Cvec%7BF%7D.%5Cvec%7Bd%7D%5C%5C%5C%5CW%3D%20%282%5Chat%7Bi%7D%20%2B%205%5Chat%7Bj%7D%29.%28%5Chat%7Bi%7D%2B%5Chat%7B2j%7D%29%5C%5C%5C%5CW%20%3D%20%282%5Ctimes%201%29%20%2B%28%205%5Ctimes%202%29%20%5C%20kJ%5C%5C%5C%5CW%20%3D%2012%20%5C%20kJ)
W = 12000 J
Therefore, work done by force is 12000 J .

Answer:
Process of Green Revolution
Explanation:
Green Revolution is a process which started its initiatives between the 1950s and 1960s, a technological research process, that increase agricultural productions through various systematic approach, which are different from the traditional methods. These technological approach includes:
1. Utilization of new varieties with a high yield potential, in addition with adequate water supply, pesticides and fertilizers.
2. New methods of cultivation and mechanization
Hence, the process of Green Revolution boosted production of fertilizers and strengthen the agriculture industry as a whole.
