Answer:
Medical uses: The field of genetic engineering is making progress rapidly and it has helped doctor's to fight many challenging diseases. One of the medical use of genetic engineering is the production of insulin by genetic engineering and also the production of vaccines through this technique.
Agricultural uses: The field of biotechnology can change the life of farmers once it is fully known that the genetically engineered crops cannot harm the humans. One of the uses of genetic engineering in agriculture is the production of crops containing increased nutrition. For example,Golden rice which carries vitamin A in it.
Environmental uses: Genetic engineering is used to clean the Earth by producing genetically engineered microorganisms which can not only break down waste but also can degrade plastics.
Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming

Work done = 100J
Distance = 5 meters
Force = ?

Force = 100/5 = 20N
Therefore, the force needed is 20 Newtons
