What is required for an electric charge to flow through a wire?

Physics

In order to persuade the electrons in the wire to flow, you need
a potential difference between the ends of the wire.  Then the
electrons will want to get away from the more-negative end and
go to the more-positive end.  If both ends of the wire are at the
same potential, then the electrons have no reason to go anywhere,
and they just stay where they are.

The correct answer is:

D. A difference in electric potential.

A difference in electric potential is required for an electric charge to flow through a wire.

An underground gasoline tank can hold 1.07 103 gallons of gasoline at 52.0°F. If the tank is being filled on a day when the outd
Damm [24]

Answer:

1069.38 gallons

Explanation:

Let V₀ = 1.07 × 10³ be the initial volume of the gasoline at temperature θ₁ = 52 °F. Let V₁ be the volume at θ₂ = 97 °F.

V₁ = V₀(1 + βΔθ)  β = coefficient of volume expansion for gasoline = 9.6 × 10⁻⁴ °C⁻¹

Δθ = (5/9)(97°F -52°F) °C = 25 °C.

Let V₂ be its final volume when it cools to 52°F in the tank is

V₂ = V₁(1 - βΔθ) = V₀(1 + βΔθ)(1 - βΔθ) = V₀(1 - [βΔθ]²)

    = 1.07 × 10³(1 - [9.6 × 10⁻⁴ °C⁻¹ × 25 °C]²)

    = 1.07 × 10³(1 - [0.024]²)

    =  1.07 × 10³(1 - 0.000576)

    = 1.07 × 10³(0.999424)

    = 1069.38 gallons

How could you use the physical properties of melting poin and boiling point to identify a substance?
Vanyuwa [196]

By comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.

<h3>What is melting point?</h3>

The melting point is the point at which the solid would change to liquid. The boiling point is the point at which a liquid would change to gas. Now we know that the melting and the boiling point of a signature of a compound and can be used to identify a pure substance.

Hence, by comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.

morpeh [17]

During the evacuation of a system containing large amounts of moisture, it may be necessary to prevent freezing by increasing pressure using a gas such as Nitrogen

The scientific name for nitrogen is N, and it is a flavorless and colorless element. The ground beneath our feet contains nitrogen, as does the water we drink and the air we breathe. In fact, nitrogen makes up the majority of the atmosphere on Earth, making up around 78% of the atmosphere.

Nitrogen, which is necessary for plant growth, can be "fixed" by lightning or given to soils through fertilizers. a flavorless gas with no color. The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. Nitrogen is always represented as N2 when it is in a gaseous state. It belongs to the group of seven diatomic molecules.

The final position minus the initial position is the
ycow [4]

Answer:

Displacement.

Explanation:

The change in between the starting position (initial position) and your final position is the amount of distance you <em>actually </em>traveled.

For example, you can use a triangle. The distance you travel for side length a  & b is equal to the distance you travel on side c (the hypotenuse). You are pretty much solving for the hypotenuse in this case, or the displacement.
