Switched Circuit: This type of connection only maintains a dedicated physical circuit or path between two network nodes for the duration of the connection before data may be transmitted.
<h3>What do you mean by circuit?</h3>
A circuit in electronics is a complete circular channel via which electricity flows. A current source, conductors, and a load make up a straightforward circuit. The term circuit can be used in a broad sense to refer to any permanent path that energy, data or a signal can go through.
<h3>What are the 3 types of circuits?</h3>
Circuits can be divided into three categories: series, parallel, and series-parallel. The typical configuration of a single electrical circuit includes one or more resistance or load devices.
<h3>What function does a circuit represent?</h3>
The closed loop in which electricity can move is referred to as a circuit. Electricity can flow in a closed circuit without interruption from the power source through the conductor or wire to the load before returning to the ground or power source.

Answer:
Explanation:
1.wrap bar magnet in a plastic baggie and remove the iron filings from the mixture by using a bar magnet. Place a small piece of scrap paper on the scale and “tare” the scale. Then place filings on the scrap paper and record (e) the mass of the iron filings. Don't throw out the iron–save it to be recollected.
2.When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
3.Sand (mostly silicon dioxide) is not.
Pour the salt and sand mixture into a pan.
Add water. ...
Heat the water until the salt dissolves. ...
Remove the pan from heat and allow it to cool until it's safe to handle.
Pour the salt water into a separate container.
Now collect the sand.
Pour the salt water back into the empty pan.
Heat the salt water until the water boils. Continue boiling it until the water is gone and you're left with the salt.
Another way you can separate the salt water and sand is to stir up the sand/salt water and pour it through a coffee filter to capture the sand.
One protons and also it grouped their because how it reacts with other materials such as other substances or materials
Answer:
All magnets have two poles: the North Pole and the South Pole.
Magnets attract ferromagnetic materials such as iron, nickel, and cobalt.
The magnetic force of a magnet is stronger at its poles than in the middle.
A freely suspended magnet always points in North-South direction.
Hope this helps
