The recoil of a 100gram cannon creates a momentum of -200g*m/s. What was the velocity of the cannon? Please help!!
Is it:
A:2m/s
B:-2m/s
C:5m/s
D:0m/s

P. S.If you answer it with no answer then i will REPORT you and make sure you don’t get points just saying!!!BTW IF I GET IT WRONG THAT MEANS U JUST WANTED THE POINTS AND YOU JUST GUESSED SO I WILL REPORT U TOO

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.

a bird that nests only in a particular tree species.

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).
