Plugging in a lamp is not an example of Static electricity. Thus, the correct option is C.

<h3>What is Static electricity?</h3>

Static electricity may be defined as the consequence of an imbalance between negative and positive charges in an object. It does not involve the direct flow of electrons throughout a wire.

Clothes sticking together in the dryer and getting shocked when you touch a doorknob are examples of static electricity while plugging in a lamp is an example of mobile electricity that mediates the direct flow of electrons to generate an electric current and as a result, the lamp glows.

Therefore, the correct option for this question is C.

The name of the SI unit force

Lelechka [254]

Answer: Newton

Explanation:-

Force is defined as an interaction that causes an affected object to be pushed or pulled in a certain direction.

$Force=m\times a$

where m= mass of an object

a = acceleration of the object

S.I unit of mass is kg and S.I units of acceleration is $ms^{-2}$

Thus For S,I units of force:

$Force=kg\times ms^{-2}=1Newton$

If two objects are in thermal equilibrium, do they have the same thermal or internal energy?

Tpy6a [65]

Answer:

Yes, they do have the same internal energy.

Explanation:

The thermal balance refers to when there is no heat transfer between the bodies and their surroundings i.e. the bodies and the environment are at the same temperature.

Suppose two bodies of different masses and different materials, each one of them is at a temperature of 25(° C), which is the same temperature as the temperature of the environment, if these two bodies are close to each other, there is also heat transfer as they are at the same temperature, in the absence of any type of energy that enter or exit in these bodies, the amount of internal energy will be equal in both bodies.

Note: when the internal energy of one of these bodies is increased, heat transfer will happen, always looking for the thermal balance.

What could be done to change this carbide ion to a neutral carbon atom? remove 2 electrons add 2 electrons remove 4 electrons ad

ollegr [7]

A carbide ion is an anion of carbon atom with two carbon atoms with a triple bond connected to each other. Since this carbide ion is a negatively charged ion, in order to convert carbide ion to its neutral carbon atom, it has to give up/remove four electrons.

An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.51 μC/m2. Another infini

NNADVOKAT [17]

Answer:

E_total = 5.8 10⁴ N /C

Explanation:

In this problem they ask to find the electric field at two points, the electric field is a vector magnitude, so we can find the field for each charged shoah and add them vectorally at the point of interest.

To find the electric field of a charged conductive sheet, we can use the Gauss law,

Ф = E. d S = $q_{int}$ / ε₀

Let us use as a Gaussian surface a small cylinder, with the base parallel to the sheet, the electric field between the sheet and the normal one next to the cylinder has 90º, so its scalar product is zero, the electric field between the sheet and the base has An Angle of 0º, therefore the scalar product is reduced to the algebraic product.

Let's look for the electric field for plate 1

The total flow is the same for each face, as there are two sides of the cylinder

2E A = q_{int} /ε₀

For the internal load we use the concept of surface density

σ = q_{int1} / A

q_{int1} = σ₁ A

Let's replace

2E A = σ₁ A /ε₀

E₁ = σ₁ / 2ε₀

For the other plate we have a field with a similar expression, but of negative sign

E₂ = -σ₂ / 2ε₀

The total field is,

E_total = σ₁ / 2ε₀ + σ₂ / 2ε₀

E_total = (σ₁ + σ₂) / 2ε₀

Let us apply this expression to our case, when placing a sheet without electric charge, a charge is induced for each sheet, the plate 1 that has a positive charge the electric field is protruding to the right and the plate 2 that has a negative charge creates a incoming field, to the right, as the two fields have the same address add

The conductive sheet in the middle pate undergoes an induced load that is created by the other two plates, but because the conductive plate the charges are mobile and are replaced.

E_total = (0.51 +0.52) 10⁻⁶ / 2 8.85 10⁻¹²

E_total = 5.8 10⁴ N /C

Note that the field is independent of the distance between the plates
