Explanation:

If the conductor has developed the potential difference. It simply means it is charged.

A conductor can be charged in different scenarios, let's discuss some of it and try to deduce the appropriate meaning for this question.

A conductor can be charged due to ions or

A conductor can be charged if it come across any current carrying conductor, so as to gain induced emf.

So, In both of these case, both can be very reasons for its potential difference.

Answer:

unequal

Explanation:

White light is a combination of all colors in the color spectrum.

Answer: C) equal

If you use a glass prism, you can split white light into a rainbow which shows all of the colors along a spectrum. Each little color slice is the same width. In other words, something like green doesn't dominate the spectrum and take up a wider portion compared to other colors.

Answer:

t = 2 hours

Explanation:

Given that,

Distance of the town, d = 90 miles

Speed, v = 45 mph

We need to find the time to get there. The speed of an object is given by :

[tex]v=\dfrac{d}{t}[/tex]

Where

t is time

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{90}{45}\\\\t=2\ h[/tex]

So, the required time is 2 hours.

Answer: We prefer a convex mirror as a rear-view mirror in vehicles because it gives a wider field of view, which allows the driver to see most of the traffic behind him. Convex mirrors always form a virtual, erect, and diminished image of the objects placed in front of it.

Answer:

when energy changes from one form to another, it always goes from a more useful to a less useful form. This means that people can't recycle or reuse high quality energy to perform useful work.

When energy changes from one form to another, it always transitions from a more helpful to a less useful one. Because of this, people are unable to reuse or recycle high-quality energy to complete crucial tasks.

Coal is most frequently and significantly used in combustion, where heat is produced to create steam, which in turn powers the turbines that generate electricity. All living things, including humans, are composed of carbon. However, as coal burns, its oxygen reacts with airborne oxygen to generate carbon dioxide. Although dioxide (CO2) is an odourless, colourless gas, it is one of numerous gases found in the atmosphere that can retain the heat from the planet.

It's a major issue for climate change since it produces more carbon dioxide when burned than oil or gas. In addition to producing microscopic soot particles and hazardous substances like arsenic and mercury, coal also contributes to air pollution.

Answer:

The layers of rock at Earth ’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed. By studying this rock record from the very beginning, it is thus possible to trace their development and the resultant changes through time.

Answer:

Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.

Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.

Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.

Nonmetals are plentiful and useful. These are among the most commonly used:

Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.

Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.

Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.

Explanation:

Answer:

 person a₁ = -0.625 m / s², box a₂ = 0.0714 m / s²

Explanation:

In this exercise we have a problem of action and reaction forces, the force with which the person (action) pushes the box is of the same magnitude as the force with which the box (reaction) pushes the person, but in the opposite direction.

We work that body separately

Person

           -F = m₁ a₁

             a₁ = -F / m₁

             a₁ = -50.0 / 80.0

             a₁ = -0.625 m / s²

the negative sign means that the person moves away from the box

Box

            F = m₂ a₂

            a₂ = F / m₂

            a₂ = 50.0 / 700

            a₂ = 0.0714 m / s²

Answer:

The acceleration of a car would be:  [tex]a=12.8[/tex] m/s²

Explanation:

Given

Initial velocity = [tex]v_1=0[/tex] m/s

Final velocity = [tex]v_f=100[/tex] m/s

Time elapsed = [tex]t = 7.8[/tex] s

To determine

We need to determine the acceleration of a car.

We know that acceleration is basically the rate of change in velocity over time.

Thus,

We can determine the acceleration using the formula

[tex]\:\:\:a=\:\frac{v_f-v_i}{t}[/tex]

where

now substituting the values [tex]v_1=0[/tex],  [tex]v_f=100[/tex], and [tex]t = 7.8[/tex] in the formula

[tex]\:\:\:a=\:\frac{v_f-v_i}{t}[/tex]

[tex]a=\:\frac{100-0}{7.8}[/tex]

[tex]a=\frac{100}{7.8}[/tex]

[tex]a=12.8[/tex] m/s²

Therefore, the acceleration of a car would be:  [tex]a=12.8[/tex] m/s²

Answer:

She will use one 2 as a subscript.

Explanation:

Nitrogen is a chemical element with the symbol "N" and has an atomic number of 7. Thus, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.

On the other hand, oxygen has an atomic number of 8 and with the symbol "O."

When nitrogen and oxygen react chemically, they produce a compound known as nitrogen dioxide [tex] NO_{2} [/tex]

In this scenario, Jenny is studying a compound that has two oxygen atoms and one nitrogen atom. Therefore, the statement which describes the subscripts she will use to write the chemical formula is, she will use one 2 as a subscript.

[tex] N + O_{2} ------> NO_{2} [/tex]

Where: 2 represents the subscript of oxygen.

Answer:

A- she will use 2 as a subscript

Answer:

1. Chlorine = 7 valence electrons.

2. Sulphur = 6 valence electrons.

3. Magnesium = 2 valence electrons.

Explanation:

In Chemistry, valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

1. Chlorine = it is an element found in group (7) of the periodic table known as halogens and as such it has 7 electrons in its outermost shell. Therefore, Chlorine has seven (7) valence electrons.

Sulphur = this element is found in group (6) of the periodic table and as such it has 6 electrons in its outermost shell. Therefore, Sulphur has six (6) valence electrons.

Magnesium = this element is found in group (2) of the periodic table and as such it has 2 electrons in its outermost shell. Therefore, Magnesium has two (2) valence electrons.
