Answer:  Fessender oscillator

Created by Reginald A. Fessenden, <u>motivated by The Titanic tragedy.</u> It was the first successful acoustical echo ranging system. Given its properties (540‐Hz air‐backed electrodynamically driven clamped‐edge circular plate), morse code could be used to communicate between submarines. During the First World War, the Royal Navy also used it for detecting submarines.

The only disadvantage that this system had, it's that it was reasonably easy to be heard by other ships, even on the surface. On the other hand, it was only useful for detecting big targets, as for little ones, it lacked power

How do the length of the lines, the stanzas, and the poem as a whole affect the meaning of we real cool a.The length of these el
ELEN [110]

Answer: d.The length of these elements reflects and stresses the importance of the speakers' actions.

Explanation:

The poem <em>We Real Cool</em>  by <em>Gwendolyn Brooks</em> speaks of the actions of a what we can assume are a group of teenagers. They skip school, they play pool, they stay out late and they drink strong liquor and so they think they are cool but know they will die soon.

We learn all these from very short lines and stanzas which were done that way to stress the importance of the actions of the teenagers. Gwendolyn Brooks did not want the actions of the speaker to be lost in a lot of words but instead wanted the actions of the speaker to be well pronounced such that the reader understands the impact that the actions of the speaker could have on them.
