Electrons flow through a wire because THERE IS A DIFFERENCE IN THE POTENTIAL ENERGY. The correct option is B.

The potential difference that exist between the electrons in an electric wire is the major reason why electrons flow through electric wires. The potential difference can be negative or positive depending on the movement of the charges. The amount of work that is needed to move a charge between two point in an electric circuit is called electric potential difference and it is measured in Volts.

What are the states of matter water goes through during the water cycle

enyata [817]

It can go through the all the states: solid, liquid, and gas.

On the ground, it is a liquid as water. Then, it evaporates and becomes water vapor, a gas. As it condensates, little droplets of vapor come together. Then, it falls to the Earth as liquid water or frozen as solid snow/sleet/hail in precipitation.

Hope this helps!!

7. Mildred was driving 12 m/s and slowed

Alenkinab [10]

Answer:

The acceleration of Mildred is, 1.33 m/s²

Explanation:

Given data,

The initial velocity of Mildred, u = 12 m/s

The final velocity of Mildred, v = 8 m/s

The time period of travel, t = 3 s

The acceleration of Mildred,

a = (v-u)/t

a = (8 - 12) /3

= -4/3

= -1.33 m/s²

The negative sign indicates that the Mildred is decelerating.

Hence, the acceleration of Mildred is, 1.33 m/s²

100j of heat energy are transferred to 80 g of mercury. By how much does the temperature increase?

olchik [2.2K]

Given: Heat given to mercury (Q) = 100 J

Mass of mercury (m) = 80 g = 80 × 10⁻³ kg

Specific Heat capacity of mercury (c) = 138 J/kg°C

Let the rise of temperature be Δt

Formula Used: Q = mcΔt

Here, all alphabets are in their usual meanings.

Calculation:

Q = mcΔt

or, Δt = Q / mc

or, Δt = 100 J /[(80 × 10⁻³ kg)×(138 J/kg°C)]

or, Δt = 9.058 °C

or, Δt = 9.1 °C

Hence, the required increase in temperature will be 9.1 °C.
