Answer:
Because he heard a patient’s yelp through a copper wire, Antonio Meucci invented the “talking telegraph.”
Explanation:
A cause-and-effect relationship is a relationship where one event causes another to happen. The first event is referred to as the cause and its result is referred to as the effect.
Here, we have Antonio Meucci, a trained engineer who created the <em>talking telegraph</em> after hearing a patient's yelp through a copper wire. His engineering knowledge was necessary for this invention, but it isn't the cause. If he hadn't heard the patient's voice through the wire, he probably wouldn't have thought of the talking telegraph.
This is the fourth option is the correct one.
Answer:
Longitudinal Waves and Transverse Waves Mechanical waves are categorized by their type of motion and fall into any of two categories: transverse or longitudinal. Note that both transverse and longitudinal waves can be periodic and Like transverse waves, longitudinal waves do not displace mass. The difference is that each particle which makes up the medium through which a longitudinal wave propagates oscillates along the axis of propagation. ... Matter in the medium is periodically displaced by a sound wave, and thus oscillates.
