Explanation:
Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip.

Chemical properties include corrosive, change in concentration of hydroxide ions when added to water, and forms hydrogen gas when in contact with a metal.
Physical properties of matter are those properties that are determined using senses or instruments. Hence, odor, taste, and texture are physical properties.
The chemical properties of a substance describe how the substance is converted to another substance.
Corrosion is the property of a substance that creates rust under the influence of oxygen from the air.
Some metals in contact with water produce hydroxides where hydrogen is also formed.
A concentration of hydroxide ions in the solution decreases due to dilution when water is added.
Evidence for the particle nature of light are not: 1. refraction, 2. many colors of light, 3. diffraction. These are all phenomenon that support wave theory of light. Evidence for particle nature of light is photoelectric effect. Because it was discovered that you need discrete energies of light to eject electrons from a metal surface and not continuous as the wave theory of light suggests.
The answer is disturbance; energy.
Waves deliver a method of transporting energy without
transporting matter. Undertaking of the particles are similar to the motion of
the energy. Sound waves touching over the air is an instance
of this kind of wave.
