It just does what it do's
Work is the transfer of force
No, There's difference b/w that work. If they no how to work then they can do!
Work input is the information and tools used to create the final product. Raw material is considered work input for products.
Electricity travels in a closed circuit when it does work.
No, this will not work. Postitive to Negative/Negative to Positive will work.

In the Control Room; Sonar was very basic then, utilizing only a 2-head hydrophone array, and a very basic display.
Marine biologists use hydrophones to record underwater sounds.
A Hydrophone. This is a waterproof microphone essentially. For simple work at modest depths, you could use an ordinary microphone, making very sure that it and its leads were well waterproofed.
A hydrophone is a microphone used to capture and record underwater sound. It is commonly used in marine research, underwater acoustics, and for detecting sounds in underwater environments such as in submarines, seismic exploration, and marine mammal studies.
The hydrophone was developed first. It was around back in Da Vinci's time, and the first recorded use dates from about 1490. Stick the large end of a "horn" of some kind in the water and listen to the little end to see what you can hear. That's a hydrophone. Sonar came along later, like in the early 1900's. It was being developed at the time electronics was advancing, and it is with the application of modern electronics that we can make the most effective use of this remarkable imaging tool. A link is provided to the Wikipedia article on sonar, and the "History" part of the article is short and easy to read.
Both O sounds in hydrophone are the long O (oh) sound. The first instance is seen in the words pyromania, gyroscope, and cryogenic. The second instance in the words bone, stone, and alone. The long O appears in several spellings: - words with an O (go, comb, cold) - words with an O with a silent E (code, hole) - words with an OE (doe, foe) - words with OUGH (dough, though) - words with OW (flow, mow, row)
