The boat would make no progress.
It is true that moving current has electrical energy.
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
What causes an electric current to keep moving is a steady supply of electrons.
The relation between electric current and drift velocity is that they both happen to involve electrons moving opposite of the electric field. The electric field must also have a conductor.
Current(I).
Yes, it is like a shrinking conveyor belt. If the conveyor belt stops moving, then it is no longer classified a glacier; it is then an ice field.
Presumably because when going in they were heading upstream against the current, while on coming out they were moving with the current.
Points b and d Irrigation depends on the River Nile which as a broad slow moving river was ideal for transportation. Steady winds blowing from the north, the opposite direction to the flow of the Nile. This allowed boats to drift on the current downstream and sail upstream against the current.
It efect the dam because on of the dams is moving a way and the other dam is going the other way and if the dam is built right were the river conects it would efect the river or stream.
Glaciers or moving, shifting and melting constantly. The worst that could happen is if too meltwater was created by the melting glacier it would cause a flood downstream.
A retreating glacier is one that is diminishing more in length that its upper supply regions can compete with. The snout of the glacier is retreating, but the main body of the glacier is still moving forwards. If this situation continues, the glacier will disappear.
you can be fined
Moving water can easily sweep pedestrians and vehicles downstream. The water does not need to be moving fast, but obviously, flash flooding imposes the greatest risk. Vehicles can be engulfed or overturned. People can be carried downstream for miles and drown from fighting the water.
Rafting is in essence a good example for the laws of physics. The water moving under and around the raft propel it forward because the water pushing against the raft has more mass then the raft can use to push back against the water. Once moving, it can be difficult to change the direction of the raft, or slow it down, because of inertia. Gravity in itself is the driving force of rafting. water flows downhill because of gravity, so water will push a raft downhill. As such, it takes much greater effort to move upstream then it does to move downstream, and may be impossible to move upstream in some areas (such as white water rafting) due to the extreme amount of pressure pushing the raft downstream.
Yes. That means you are swimming downstream, not upwards. Think about it. :)
The maximum speed that a vessel will achieve relative to ground is its own maximum speed through water plus the speed of the the moving water downstream.
An upward moving current of air is called an updraft.
