What is the best description of a wave? a pulse that carries energy a disturbance that moves matter a medium disturbed by a vibration matter that is moved from one place to another

a pulse that carries energy

Explanation:

A wave is defined as a periodic disturbance (also called 'pulse') which carries energy, but not matter, through a medium (or through a vacuum).

Waves can be classified into two types:

- Mechanical waves: these waves consist of periodic oscillations of the particles of a medium. Examples of mechanical waves are sound waves. This type of waves can propagate only through a medium, so they cannot travel through a vacuum.

- Electromagnetic waves: these waves consist of periodic oscillations of electric and magnetic fields. This type of waves can propagate both through matter and through a vacuum, because they do not need a medium for the oscillations to occur.

The answer is A) a pulse that carries energy

Explanation:

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
