2.✓ A Tree is a connected acyclic undirected graph. There is a unique path
3.✓ Outstanding electrical properties include high insulation resistance, high dielectric strength, low dielectric constant, low dielectric loss at all frequencies, excellent resistance to cold flow, and good abrasion resistance.
4.✓ . A car has properties like weight and color, and methods like start and stop. All cars have the same properties, but the property values differ from car to car. All cars have the same methods, but the methods are performed at different times
5.✓ The Properties of Water
In nature, water exists in the liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at 0 degrees Celsius and 1 atm of pressure. At room temperature (approximately 25 degrees Celsius), it is a tasteless, odorless, and colorless liquid.
6.✓ The Properties of Air
Air takes up space.
Air has mass.
Air is affected by heat.
Air exerts pressure.
Air can be compressed.
Air is affected by altitude.
7. × Rainbows are the result of the refraction and reflection of light. Both refraction and reflection are phenomena that involve a change in a wave's direction. A refracted wave may appear "bent", while a reflected wave might seem to "bounce back" from a surface or other wavefront.
