An object with a mass of 2000 g accelerates 8.3 m/s2

To find force is M x A the mass has to be in kg so 2000g = 2 kg and A= 8.3 m/s2  so 2 x 8.3 = 16.6 then the force is 16.6 newtons.

Explanation:

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
