An accepted and universally true explanation of observed facts is a law.
Answer:
The correct answer is - They are mechanical waves.
Explanation:
Atomic bombs after detonated they send a shock wave that makes a movement of particulate matter that leads to transfer of a high amount of energy that superheats the air medium that travels as a mechanical shock wave.
The shock wave that is sent out by a detonated atomic bomb is a longitudinal mechanical wave that transfers the energy to the neighboring particles of the air.
Answer: The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second. Also it is measured in Hertz.
Explanation:
<u>Answer:</u> The net ionic equation is written below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of calcium iodide and chromium (III) sulfate is given as:
Ionic form of the above equation follows:
As, chromium and iodide ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation is written above.
Answer:
Solids
Liquids
Explanation:
Condensed states of matter are those states of matter in which the particles that compose matter are close together. This implies that the molecules that compose matter are closely packed. This influences the density of such condensed states of matter.
Two examples of condensed states of matter are solids and liquids. In these two states of matter, particles of matter are close to each other and intermolecular interaction is significant.
