Answer
Brief Explanations:
- For Question 1: En HeduAnna is considered one of the first - known female astronomers. Archimedes was a mathematician and inventor, Pluto is a dwarf - planet, and Aristotle was a philosopher.
- For Question 2: Aristotle made contributions to the development of the scientific method. Calculus was developed by Newton and Leibniz, pendulum clocks were related to Galileo and Huygens, and there is no connection between Aristotle and Ship Shaker.
- For Question 3: Archimedes used the principle of buoyancy. He compared the buoyant force on the crown with that on a pure gold sample of the same weight. If the crown was made of pure gold, it would displace the same volume of water as the pure gold sample. If it was mixed with a less - dense metal, it would displace more water.
