Answer:
An example of vibration by mechanical waves is sound waves.
Explanation:
Mechanical waves are those capable of transmitting energy, which can propagate in the same direction, resulting in an alteration of the mechanical properties of a material. As a result of this, the material presents changes in the energy of its atoms and molecules.
Sound waves are mechanical waves, which require a medium for transmission and act as elastic waves capable of propagating longitudinally, producing a vibration.
Sound propagates and can produce waves in water or vibrations that reach the eardrum and enable the reception of this sound.
<em>The other options are not correct, because light and radio waves are electromagnetic waves that are transmitted in a vacuum, without producing vibrations. Reflection is a property of light.</em>
Every living thing on earth evolved from a single cell organism
The answer is to the ground.
Gravity refers to the force that holds together the universe. On Earth, the gravity attempts to change the velocity of all the objects on the Earth's surface toward the ground at a rate of 9.8 meters per second squared according to Galileo.
