A structure built across a river to control the flow of water?
A dam is a structure built across a river to control the flow of water. It helps regulate water levels, generate hydroelectric power, and provide water for irrigation and drinking. Dams can also prevent floods and create reservoirs for recreational activities.
Can water decreases substance resistance to the flow of electricityof electricity?
Yes, water can decrease a substance's resistance to the flow of electricity because it is a good conductor of electricity. Water molecules contain charged ions that enable the flow of electric current more easily compared to substances with higher resistance. However, water can also cause short-circuits and electrical hazards if not controlled properly.
How can the electromagnet be used to raise the barrier?
An electromagnet can be used to raise a barrier by creating a magnetic field when current flows through it. The magnetic field attracts the metal barrier, causing it to rise. By controlling the flow of current to the electromagnet, the barrier can be raised and lowered as needed.
What is built in potential?
The built-in potential is the potential difference established at the junction of two different materials, such as a p-n junction in a semiconductor device. It arises due to the electrostatic forces that separate the charge carriers across the junction, creating a barrier for the flow of current. This potential is an important parameter in determining the behavior of semiconductor devices.
Is fersh water a conductors or insulators?
Fresh water is a poor conductor of electricity because it does not contain significant amounts of dissolved ions that allow electric current to flow. However, impurities or contaminants in the water can increase its conductivity.
What is a barrier built to hold water or to stop its flow?
Dam
What are dam?
1 a barrier to obstruct the flow of water, esp. one of earth, masonry, etc., built across a stream or river. 2. a body of water confined by a dam. 3. any barrier resembling a dam
What is a barrier built across a river that may redirect its flow to other channels?
It is a dam or river dam. A type of low semi-barrier is a weir.
What does diked mean?
DikeNoun1. Offensive terms for a lesbian who is noticeably masculine.2. A barrier constructed to contain the flow or water or to keep out the sea.Verb1. Enclose with a dike; "dike the land to protect it from water".
A structure built with rocks to redirect the flow of water in a stream and increase they rate of the water's flow is?
watermelon

What is the physical barrier in the root that regulates the flow of water to xylem via cell walls?
The Casparian strip is the physical barrier in the root that regulates the flow of water to xylem via cell walls. It is a band of impermeable suberin found in the endodermis of plant roots creating a selective barrier.
What are built to attempt to prevent flooding?
Dams, dykes, and levees are built to control the flow of water.
What is a layer of rock that does not allow water to flow through called?
An impermeable layer of rock that does not allow water to flow through is called an aquiclude or aquitard. These layers restrict the movement of groundwater, creating a barrier for water flow.
Structure built across a river to control the flow of water?
Weir
Could you give me an example using the word flow?
A dam is built across a river to restrict the flow of water.
What is the major barrier in the US that separates the flow of water in rivers from the Pacific O cean and the Atlantic Ocean?
Continental Divide
