Answer:
d. All of the above
Step-by-step explanation:
Here is the complete question
A mechanical wave can be defined by which of the following?
a. Carries energy from one place to another
b. Moves through solids, liquids, and gasses
c. Is created when a source of energy creates a vibration
d. All of the above
Solution
A mechanical wave is an oscillation of matter which carries energy from one place to another. This oscillation of matter shows that a mechanical wave requires a medium to pass through, be it solid, liquid or gas.
A mechanical wave can usually be created by the the vibration of a medium due to a source of energy.
Examples of mechanical waves are sound waves and water waves
Since all these characterize a mechanical wave, the option d is the correct answer
