Sonar

1945, when some people tracked an object following the machine through the water at 146 meters. While mysterious, the recording could have been faulty. Once, people used sonar to detect a giant object deep in the lake. Later, with better technology, people found that it was just algae and zooplankton blooming and growing. Sonar, though, seems to be the most accurate way to find the Loch Ness so far.…

The Air Force displayed their presence in attempt to deter the German U-boats from attacking the convoys that were on route to supply our troops overseas. When a convoy would leave, the planes would fly over the convoy until sonar and radio transmission from base was broken. From there they would return to base and wait for the next convoy that they would watch over. With the Air Force flying over, the German U-boats would usually not attack as they would be greatly outnumbered…

they have a lower frequency than what we can detect with our ears. We have been researching it for hundreds of years and I believe we can for a few hundred more. These waves are used in many other applications such as fishing, to detect fish, or sonar in submarines to detect where they are. Some animals actually use infrasound to communicate over long distances…

CURING CANCER Music can kill cancer. The cells are literally exploding. Scientists across the world have been researching and testing the idea. Scientists have had samples of cancer cells and continually played music with multiple instruments. After a short period of time (9 to 15 minutes) most of the cells exploded. The treatment has also been tested on cancer patients. In one case, the tumor was completely gone. In most other cases, the tumor had decreased in size drastically. Soon,…

In the novel "Left For Dead", there is a line that says: "Knowing how the men died is not the same things as knowing why they died". This explains that you may know the way they passed away, but not the the cause of their death. One of the reasons why most of the crew members passed away is the fact that crew was simply not prepared enough for the trip. In the novel there were multiple incidents on why the Indianapolis did not succeed to get home. The most popular reason is that Captain McVay…

first reason that explains why vampire bats should be kept alive is that they are very useful to the inventing world. In the article it explains some ways that bats have helped scientists invent things such as sonar and anti-coagulant medicines: "Bat-based research led to the development of sonar and anti-coagulant…

After researching the topic of the Loch Ness Monster, I do not believe in this legend based off scientific studies and using common logic. First off connecting the details of the lake it could not support an animal of that caliber for this long. After all the extensive hours of research and looking for this animal, plus the money put into this, not one monster has been found. Humans have an incredible use of the brain called pareidola. Last, this monster is still a legend for the main reason of…

anthropogenic noise. Ships use sonars for trade routes, researchers use sonars to able to map the sea floor, and other ships use sound waves to find oil on the sea floor. 2. (10 points) How does noise pollution impact marine organisms (give 3 examples)? Lots of background noise causes masking which happens when animals cannot hear important sounds which is difficult for navigation. Without being able to navigate properly animals have the potential to get lost. Sonars can cause hearing loss…

1939, war had started between Germany and Poland and the successful attempts for expansion of Germany. After obtaining the territory of Poland, Germany rapidly move on to invade the Soviet Union, Romania, Finland, Norway, Denmark and the Dutch just between 1939 and 1940. With many more to come and fall under the command of Germany, they continued to gain territory throughout World War Two taking what they wanted most, power. But why was Germany was so successful in early World War Two? Well,…
