how does kinetic energy affect a river?
465278
Kinetic energy is the actual amount of energy in an object. In this case, it would be water.\n\nThe faster a stream flows, the more sediment it can carry. This is called the stream's carrying capacity or load.\n\nAlso, when a stream flows faster, it can pick up objects that are of larger size & heavier. It can deposit these larger items further downstream than if the stream was moving slower.\n\nWhen a stream slows down, it will lose it capacity to carry it's load & the sediments will start dropping out of the water. They are then deposited in the streambed.\n\nStreams that move faster are more likely to cut into their bed, making the stream deeper over time.\n\nHope this helps.\n\n:)

From those choices the finest particles would have to be found near the mouth. This is because along the course of a river the speed of the river varies and at the mouth is generally the slowest point. As it enters the ocean it is likely to be flowing at its slowest speed, so its ability to carry particles is at its lowest energy level and only the very smallest particles will stay suspended. \n\nHowever, the question is not really correct with that wording and with this answer. There is no reason that the very smallest particle carried by a river cannot be found at ANY of those points along the river, and transported all the way to the mouth of the river. This also ignores the fact that rivers carry dissolved solids as well.

This question can be answered quite easily, if you can consider this idea: Suppose you have some amount of water which is contained in a tub. You bury your hand inside the water and make some forward movement, obviously, the waves of the water flow directly in one direction. Whereas, if you oppose the motion of these moving waves, by burying another hand of your's and pushing some water against an already moving set of waves of water, the first set of waves defintely will decrease their speed, as being opposed by an other ENERGY. \n               So, considering this example, sound waves' problem can be solved: If you yell against the wind, your sound waves are being OPPOSED, hence their speed slows down, and they tend fade off travelling LESS distance. If the sound is going in the direction of the wind, it will definitely tend to move FASTER(when compared to it, moving against the wind)as it is NOT BEING OPPOSED by any other form of energy. \nThat's it mostly,\ncheers,\nDa Vinci.

kinetic energy is 1/2 mv² so it depends on mass and velocity

It is the transformation of potential energy, converted into kinetic energy, which in turn is converted to hydroelectric energy by the means which you described....KECK

figure the bottom, the top gets fed more water as it flows down river by rain, the bottom gets its water from runoff - the effect of the rain up-stream.

It's bernoulli's principle. Fluids have a lower pressure when moving than when still. Since the water is moving past the spoons (which act like the wing of a plane) they feel a pull from the pressure drop and come together. Try it with a peice of paper sometime. Roll a piec of paper up so when you place it on a flat surface it looks like a curved bridge. then blow under it and it will collapse instead of blow away. It's pretty neet.

To calculate the kinetic energy, you need to know the velocity of the steamboat at which it is travelling.  Taking ke = 0.5mv^2, you will be able to calculate the kinetic energy.  You can find the velocity by dividing the distance travelled by the time taken to travel this distance.  One problem you will face is that the speed of the steamboat may not be uniform, and hence, you can't use the ke = 0.5mv^2 formula.\n\nTo find the effects of the various factors, such as hole size and number of candles used, you must only vary one factor at a time.  For example, conduct a series of experiment using different number of candles with the same hole size.\n\nNope, you can't equate kinetic energy to the thermal energy produced.  You have to take into account of water resistance due to the viscosity of water which is significant.  [I'm assuming that you are conducting the experiment in water since you call it a 'steamboat'].  If you conduct the experiment in air, you may be able to assume air resistance to be zero.

Nothing. The river just flows from it. If it has multiple sources or headwaters, however, then the actual river flows from the largest or main source, and is connected to the other headwaters through tributaries.

In the steady state, water flows out of the aqueduct, leaving the force on the floor&walls unchanged. However, then the barge is first introduced, the displaced water flows as a wave, causing greater forces near the wave-front.

only energy is transferred.  Think about it - if you're in the  ocean and a wave comes by, you bob up and down but aren't swept away.

There is headward erision (where the upper course erodes at the head), Gulley Erosion( where it forms gorges and gulleys) and there is erosion by debris(bigger rocks or stones along the river bed). These can also cause potholes in the river bed.

That would be a natural levee.\n\nWhen the river's water exceeds its banks, the water begins to slow down.\n\nThe slower velocity will cause the heaviest of the sediments to "fall out".\n\nSome of the sediment will be deposited on the banks of the river forming a natural levee.

I think it takes same amount of energy to get water flowing uphill in a certain angle, direction, or distance.\n\nLeast energy intensive in fact does not make any sense.\n\nIt takes definite amount of potential energy to move any object up a same distance if they weigh the same.

If you're referring to a reverse flow due to natural OR artificial causes, the most noteworthy is the North fork of the South Branch of the Chicago River. This was reversed to have sewage flow down the Great Lakes/Mississippi waterway. The North Branch and South Fork of the South Branch were unaffected.\n\nSpeaking only of natural phenomena, there would, I am sure, be many. One I know of for sure is the Mekong, which is so close to sea level that the twice daily tides cause it to reverse flow and actually flow backward in some areas.

Deltas are not so much dependent on overflow of a river as they are on the amount of sediment a river is carrying & the velocity of the river.\n\nDeltas form from sediments "dropping out" of a river.\n\nDropping out refers to the sand, silt, and clay becoming to heavy for the river to carry.\n\nA river's carrying capacity (how much sediment it can carry at one time) is determined by how fast it is moving. The velocity is determined by how wide the channel is & how much water is running through it at one time.\n\nWhen a river nears the ocean it begins to slow down due to gravity and nearer the ocean, tidal interference. It's carrying capacity is lowered greatly.\n\nThe heaviest of the sediments begin to drop out first. This would be sand. The next would be silt. By the time it reaches the brackish water near the ocean, the clay will become too heavy due to interaction w/ the salt water. It too will "drop out".\n\nOver time, layers of sediment are built up. Eventually they will reach and exceed the water level of the river. This is the beginning of a delta.\n\nDeltas only form in river dominated areas. This means the areas where the amount of water & sediment from a river greatly outweigh the "strength" of the tides. Deltas will not form in areas where tides are strong. The sediment would be washed away by the action of the tides.

its all to do with weight displacement and the volume of water
