What else can I help you with?
A boat moves at a speed of 15 kmh in still water. The river it is traveling in flows at a rate of 3 kmh downstream. What is the velocity of the boat if it travels downstream What is the velocity of th?
If the boat is moving downstream, you add the speed of the boat with the speed of the river flow. Therefore, the velocity of the boat downstream is 18 km/h. If the boat is moving upstream, you subtract the river flow speed from the boat's speed, so in this case, it would be 12 km/h.
True or false Moving current has electrical energy?
It is true that moving current has electrical energy.
Does a stream's velocity increase or decrease downstream?
A stream's velocity typically increases downstream due to the accumulation of water volume and slope gradient. This leads to higher flow rates and faster-moving water.
Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
What are moving electrons known as?
Moving electrons are known as electric current.
When a glacier is retreating does the upstream ice is still moving forward toward the downstream terminus of the glacier?
Yes, even when a glacier is retreating, the ice in the upstream region is still moving slowly forward towards the downstream terminus. This movement is due to the constant flow of ice within the glacier caused by gravity and pressure.

True or false When a glacier is retreating the upstream ice is still moving forward toward the downstream terminus of the glacier?
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.
Why were they able to travle out faster on the thirty mile river as opposed to going in call of the wild?
Presumably because when going in they were heading upstream against the current, while on coming out they were moving with the current.
How do you set up the equation to find current of a river?
To set up the equation for finding the current of a river, you typically consider the speed of a boat relative to the water and the speed of the boat relative to the ground. Let ( v_b ) be the speed of the boat in still water, ( v_r ) be the speed of the river current, and ( v_g ) be the speed of the boat relative to the ground. The equation can be expressed as ( v_g = v_b + v_r ) when the boat is moving downstream and ( v_g = v_b - v_r ) when moving upstream. By measuring the ground speed in both directions, you can solve for ( v_r ).
Which of these was most helpful for transportation in ancient Egypt a annual deserts b extensive irrrigation c flat desert or d steady winds?
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.
How does a dam affect the amount of water in the watershed upstream and downstream from the dam?
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.
If a glacier moved down the mountain what would happen?
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.
Which of the folliwing is an example of moving surface water?
A river flowing downstream is an example of moving surface water.
Moving to Ontario What can happen if you decide NOT to exchange your current driver license for an Ontario license?
you can be fined
Can easily sweep pedestrians and vehicles downstream?
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.
How does rafting use science?
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.
