A large cooler is filled with water, as shown below.

A large yellow cooler with a white valve at its bottom.
How does the valve on the cooler compare with the switch in an electric circuit?

Opening the valve allows water to flow, just like opening a switch allows charges to flow.
Opening the valve stops the flow of water, but closing a switch stops the flow of charges.
Closing the valve stops the flow of water, but opening a switch stops the flow of charges.
Closing the valve allows water to flow, just like closing a switch allows charges to flow.

Opening the valve allows water to flow, just like opening a switch allows charges to flow.

Which statement describes an open circuit?

The circuit is incomplete and broken, and the lights in the circuit shine.
The circuit is complete and unbroken, and the lights in the circuit shine.
The circuit is incomplete and broken, and the lights in the circuit do not shine.
The circuit is complete and unbroken, and the lights in the circuit do not shine.

The circuit is incomplete and broken, and the lights in the circuit do not shine.

How do the lights in a series circuit behave when one bulb burns out?

The rest of the bulbs continue to shine at maximum brightness.
The rest of the bulbs continue to shine at a lower brightness.
The rest of the bulbs continue to shine at a higher brightness.
The rest of the bulbs stop shining and shut off.

The rest of the bulbs stop shining and shut off when one bulb burns out in a series circuit.

What is the main disadvantage of parallel circuits?

Any break in the circuit stops the flow of charges.
There are multiple paths for charges to flow.
If one bulb goes out, the other bulbs will go out.
They are complicated to design and build.

The main disadvantage of parallel circuits is that if one bulb goes out, the other bulbs will not go out.

Patty makes a table of the symbols used for the parts of an electric circuit.

A 2-column table with 4 rows. The first column labeled Symbol has entries circle with an X in it, short horizontal line at each end with a stack of vertical lines in the middle, which are from left to right very short, short, very short, short, a short horizontal line then a small circle then a short line pointing up at about 45 degrees then a short gap then a small circle then a short horizontal line, a sort horizontal line then a zigzag then a short horizontal line. The second column labeled Component has entries empty, empty, empty, check mark.
What label should Patty place in the marked cell?

Battery
Switch
Resistor
Bulb

Based on the given description, the label that Patty should place in the marked cell is "Bulb".

U GAVE ME 60 PERCENT >:[

anyways ill just do a retake

Which statement describes one feature of a closed circuit?

Charges do not flow.
Bulbs will not shine.
The circuit is broken.
The circuit is complete.

I apologize if my previous response was not satisfactory. The correct statement that describes one feature of a closed circuit is "The circuit is complete."

Jamal draws the circuit diagram shown.

There are three light bulbs shown in the diagram. How many of each additional component are shown?

one battery, two switches, two resistors
two batteries, three switches, two resistors
one battery, four switches, one resistor
two batteries, three switches, two resistors

Based on the given information, Jamal's circuit diagram shows one battery, four switches, and one resistor.

What symbol would best represent an electric fan speed controller in an electric circuit?

A short horizontal line then a small circle then a short line pointing up at about 45 degrees then a short gap then a small circle then a short horizontal line

A circle with an X in it.

A short horizontal line then a zigzag then a short horizontal line.

A short horizontal line at each end with a stack of vertical lines in the middle, which are from left to right very short, short, very short, short.

The symbol that would best represent an electric fan speed controller in an electric circuit is "A short horizontal line at each end with a stack of vertical lines in the middle, which are from left to right very short, short, very short, short."

A symbol from a circuit diagram is shown.

What does this symbol represent?

a switch
a light bulb
a wire
a battery

Without a description or visual representation of the symbol being referred to, it is not possible to determine what it represents. Please provide more details or a description of the symbol for further assistance.

It looks like A circle with an X in it.

The symbol that looks like "A circle with an X in it" represents a switch in a circuit diagram.

I DID EVEN WORSEE 30

One more question because this is my last thing now

Describe at least two different objects that you think are magnetic. Why do you think these objects are magnetic?

Sure! Two different objects that are typically magnetic are:

1. Refrigerator Magnet: Refrigerator magnets are often made of a material called ferrite, which is a type of ceramic material that can be easily magnetized. These magnets stick to metallic surfaces such as refrigerators due to their magnetic properties. They are commonly used to hold notes, pictures, and other lightweight objects.

2. Iron Nail: An iron nail is another object that can exhibit magnetic properties. Iron is a ferromagnetic material, meaning it can be easily magnetized and retains its magnetism even after the magnetic field is removed. When a nail is in contact with a magnet, it can become temporarily magnetized and attract other small metallic objects.

These objects are magnetic because they either contain magnetic materials or can be easily magnetized. Their magnetic properties arise from the alignment and interaction of the microscopic magnetic domains within the material, which generate a magnetic field. This magnetic field allows the objects to attract or repel other magnetic materials.
