You have to find the acceleration first. so you would use the equation a=Vf-V0/t.
This would be 0-20/0.5 which equals to be a=-40. then you plug this in to the force equation wich is F=ma. F=55 x -40. F= -2200
Hope this helps!

Answer:
- Interspecific competition between sea urchins and Stellar's sea cows
- Predation fo sea urchins by sea otters
Explanation:
As urchins and Stellar's sea cows feed on seaweed, since these algae are low in quantity, these two organisms end up competing for food, creating an inter-specific competition, which occurs when two organisms compete for the same resource within a same ecological niche. However, as the hedgehog has advantages in this niche, this competition was interrupted.
The otters' predatorism in relation to sea urchins was also interrupted, as the otters reached a very low population level, failing to control the hedgehog population and generating an environmental imbalance.
The answer to this question would be: <span>(2) cytoplasm
The nucleus is the organelle in middle of the cell that contains DNA. The ribosome is organelle that has a function in protein synthesize. Mitochondrial has a function in making the energy. Cytoplasm is water inside the cells. Everything would be stored inside it and moving material will need to pass it.</span>
