Some glass objects from ancient civilisations look milky instead of being transparent. Explain.

Text Solution

AI Generated Solution

To explain why some glass objects from ancient civilizations appear milky instead of transparent, we can break down the explanation into a few key steps: ### Step-by-Step Solution: 1. **Understanding Glass**: - Glass is classified as an amorphous solid. This means that its constituent particles (atoms or molecules) are not arranged in a regular, repeating pattern as they would be in a crystalline solid. 2. **Amorphous vs. Crystalline Structure**: ...

The orbit of Pluto is much more eccentric than the orbits of the other planets. That is, instead of being nearly circular, the orbit is noticeably elliptical. The point in the orbit nearest to the Sun is called the perihelion and the point farthest from the Sun is called the aphelion. As Pluto moves from the perihelion to the aphelion, the work done by gravitational pull of Sun on Pluto is
