From the given motions, let's determine the example which is not an example of a wave motion.
Wave motion can be defined as the transfer of energy from one point to another without the actual transfer of matter between the points.
From the given examples, the example which which we can say does not represent a wave motion is: a person dancing.
An earthquake’s energy travelling through the core of the planet is an example of wave motion since the energy travels through one point to the other.
A tsunami event occurring after an earthquake is also an example of a wave motion.
A vibrating Slinky showing crests and troughs is an example of wave motion.
While the sound of a tuba is an example of a sound wave,
Therefore, the example which does NOT represent a wave motion is a person dancing.
ANSWER:
A). A person dancing.
Explanation:
The blocks are spinning around the center of mass, but they're also sliding horizontally. So they still have a positive displacement.
