I saw the hometown great changes have taken place in the stream, streams of water have become dark and smelly; Shell to see; Fish are dead, floating on the surface of the water; And there are some rubbish floating on the water. After...
The Moon might affect our behaviour too. Writing about this for BBC Future, Claudia Hammond explains one interesting theory. Just as the Moon’s gravitational pull affects the tides, it exerts its influence on the water in our bodies. But she points out “the Moon is smaller than the Earth...
1. What is the definition of sound waves and how is the sound produced? A sound wave is the pattern of a disturbance generated by the flow of energy as it propagates away from the source of the sound across a medium (such as air, water, or any other liquid or solid matter). When ...
Technically, sound isdefinedas a mechanical disturbance traveling through an elastic medium — a material that tends to return to its original condition after being deformed. The medium doesn't have to be air. Metal, wood, stone, glass, water, and many other substancesconduct sound— many of ...
Boating and fishing significantly affects manatees because the mammals swim close to the surface of the water. According to the Florida Fish and Wildlife Conservation Commission, various types of watercraft killed 73 manatees in 2007. Florida in particular has implemented manatee protection policies such...
introduction of substances or energy that harms plant and animal life, destroy ecosystems, and change the behavior patterns of animals. There are chemical pollutants that affect land, water, and air, but there are also types of pollution involving light and sound that changes a species' behavior...
is they'll ring all the water out of it. Does a couple things. Number one, speeds up the digestion of that to make it more nutrient dense compost and or takes up some of the weight in some of the room. So you're getting a twofold bang for that. ...
Does the speed of sound in water change with higher or lower frequencies? How is ultrasound created using the piezoelectric effect? What is a Vernier caliper and how does it work? What happens to the end dialostic volume and end systolic volume when myocardial contra...
Temperature and humidity affect odor because they increase molecular volatility. This is why trash smells stronger in the heat andcarssmell musty after rain. A substance's solubility also affects its odor. Chemicals that dissolve inwaterorfatare usually intense odorants. ...
I'm sure that at some point in our lives, all of us have imitated the sound of a passing car or passing police car; we imitated the Doppler Shift. This Doppler shift also affects light (electromagnetic radiation) in the same manner with one critical exception; the shift will not allow ...
