These answers are very good. I made a 95% by using this as my answer key, but unfortunately, one of these is wrong. I don't know which one, all I know is that I got 19/20. Just wanted to throw that out there. :-) Good job, Sadaqasalaam3. And thank you.

Answer:
B. galaxies
Explanation:
Galaxies are clusters of stars, gas and dark matter. They are classified based on the shape they form. There are three main categories: Spiral, elliptical, and irregular. As their named suggests, that is what they look like.
Barred spiral galaxies are a subcategory of spiral galaxies. The nucleus of the galaxy (Center) a bar material is formed and arms branch out from the ends of it.
Some galaxies on the other hand, do not fit the main categories.
Attached is a picture of the common and uncommon categories of galaxies.
The magnitude of the force exerted by the fish is 3,052.5 N.
The given parameters;
- mass of the reel, m = 652 g = 0.652 kg
- diameter of the reel, d = 10 cm
- radius of the reel, r= 5 cm = 0.05 m
- angular speed of the reel, ω = 306 rad/s
According to Newton's third law, the force exerted by the reel is equal in magnitude to the force fish exerted on the reel.
The centripetal force of the reel = force exerted by the fish

Thus, the magnitude of the force exerted by the fish is 3,052.5 N.
