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!

Loop of Henle concentration gradient
nadezda [96]

Answer:

The Loop of Henle serves to create a concentration gradient throughout the nephron which helps increase the reabsorption of water and certain ions. In the thin descending limb, water is very permeable and is reabsorbed due to the existing concentration gradient in the medulla.

With as much detail as possible, give another example of an analogy for describing prokaryotic cells and eukaryotic cells.
Mama L [17]
<span>For example, a prokaryotic cell is an uncivilized society while the eukaryotic cell is a more systematized society, with coordination and cooperation and a leader.

Eukaryotic cells has a nucleus while prokaryotic cells do not. Eukaryotic cells have more than one chromosomes and is usually multicellular while the prokaryotic cells has only one chromosome and it's not even a genuine one, only plasmids and has unicellular however some cyanobacteria maybe multicellular. Eukaryotic cells have genuine membrane-bound nucleus, lysosomes and peroxisomes while prokaryotic cells display just the opposite of eukaryotic cells. Eukaryotic cells recombines its genes by meiosis and by the fusion of gametes while the prokaryotes does by partial and undirectional transfer of DNA.</span>
