For an observer standing on the ground with h = 2 meters (6 ft 7 in), the horizon is at a distance of 5 kilometers (3.1 mi).
The Earth curves about 8 inches per mile. As a result, on a flat surface with your eyes 5 feet or so off the ground, the farthest edge that you can see is about 3 miles away
Humans can see from 380–740 nanometers (nm)
So, the answer is no, if you can only barely see 3 miles away, then you wouldn't be able to read the name of a boat 3.1 miles away.
Answer:
Your vocabulary notebook can be used to practice the meaning of new words everyday. When you find words, you can add them in your notebook, write the definition, and the synonyms/antonyms. Let's just say you want to revisit a word because you didn't know its meaning. You then would turn to the page in your notebook and review it.
1. Try to figure out the definition by looking at its prefixes and suffixes.
2. Write the words from a textbook's glossary, and write it down in the notebook.
3. You write synonyms and the antonyms for each of your words.
