Explain how the use of technology in agriculture can improve productivity and employment in 300 words

Agriculture is a field where modern technology can severely increase yields of crops, increase the speed at which crops grow, and increase the speed at which crops can be harvested, requiring fewer man hours to complete a harvest. First, to increase crop yields, farmers can acquire genetically modified crops. While over time, humans have been able to breed crops to grow bigger and bigger, genetically modified crops are a much quicker solution to get bigger yields. The DNA of a seed is modified so corn for example can grow bigger, but there is the possible downside of mutation. As for the speed at which crops grow, genetic modification is also the answer. Finally, to increase the speed at which crops can be harvested, farmers use several tools, depending on the crops they are harvesting. For corn, farmers use grain combines, vehicles that separate the grain from its stalks. For cranberries, farmers fill the field with water, causing them to rise, and they use mechanical pickers to get them. Simply put, depending on the job at hand, a machine probably exists to complete that job. This decreases the time spent harvesting crops, and therefore decreases the amount of employment required to complete a harvest.

qaws [65]

Answer:

Explanation:

Based on the record that the male attacks the red object, the conclusion that can be made is that they recognize when the other sticklebacks are female or male thanks to their red belly and when they have to attack the other to the death, this is part of the natural selection where animals compete to simply reproduce with the female.

A basketball is dropped from the edge of a cliff at the same time that second basketball is thrown upward from the ground. When

pentagon [3]

Answer:

The collision occurs at a height of 1/3 of the total height of cliff.

Explanation:

The situation is represented in the attached figure:

For the stone dropped from top of cliff we have

Initial velocity of drop= 0 m/s.

Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as

$v_{f}=u_{i}+gt\\\\2v=0+gt\\\\\therefore t=\frac{2v}{g}$

Thus the distance it covers in this time can be calculated using third equation of kinematics as

$v_{f}^{2}=v_{i}^{2}+2gh\\\\(2v)^{2}=2gh_{1}\\\\\therefore h_{1}=\frac{2v^{2}}{g}$

For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as

$v=v_{i}-gt\\\\\therefore v_{i}=v+gt\\\\v_{i}=v+g\times \frac{2v}{g}\\\\\therefore v_{i}=3v$

The height over which it changes it's velocity from '3v' to 'v' can be again obtained from third equation of kinematics as

$v^{2}=(3v)^{2}-2gh_{2}\\\\v^{2}=9v^{2}-2gh_{2}\\\\\therefore h_{2}=\frac{4v^{2}}{g}$

$\therefore h_{2}=2h_{1}$

Thus the collision occurs at at a fraction of 1/3 of height.
