Study Notes

Circle Basics

An annulus is a ring-shaped region between two concentric circles.
The circumference of a circle is the distance around the circle.
A chord in a circle is a line segment within the circle that connects two points on the circle's circumference.
The diameter of a circle is the longest distance across the circle, passing through its center.

Solids

A solid state of matter is characterized by a fixed shape and volume.
Solid-state electronics are based on semiconductor materials, such as silicon.
When a solid is heated, its atoms or molecules gain kinetic energy and start vibrating more rapidly.
Solids tend to have a fixed shape and retain it unless an external force is applied.
Examples of solids include rocks, metals, and ice.
