Final answer:
D) Both electricity and sound. A tipped domino sending a pulse along a row of standing dominoes is a good analogy for the way both electricity and sound travels.
Step-by-step explanation:
The analogy of a tipped domino sending a pulse along a row of standing dominoes is a good representation for the way both electricity and sound travels.
In the case of electricity, when a circuit is completed, the flow of electric current starts at one point and propagates through the circuit, similar to a domino effect. The electric current moves through conductive materials, such as wires, and transfers energy along the path.
Similarly, sound waves travel as a series of vibrations that cause the movement of molecules in a medium. When a sound source initiates vibrations, such as a speaker producing sound waves, the vibrations are transmitted through the medium, like a row of dominoes, and travel to our ears.
