Answer: C. Coal power can be generated both day and night.

Explanation:

Coal is an important form of source of energy. It is a non-renewable source of energy. It is obtain by mining of the surface below the earth crust.  Coal plays an important role in generation of electricity worldwide.  

It acts as a raw material for the generation of electricity in both day and night. When the coal is turned into a gas. The gas turbine is hot enough to boil the water that can be used to make the steam. The steam spin another type of turbine so as to generate the electricity.

Answer: <u>In a divergent plate boundary</u>, seafloor spreading taking place. It leads to the formation of oceans as new materials are added here along the mid-oceanic ridge. There occur volcanism and shallow-focus earthquakes.

<u>In a convergent plate boundary</u>, two plates collide to form high mountain belts and also volcanic eruptions take place. There occur long chains of volcanic as well as island arcs, in association with deep-focus earthquakes.

<u>In a transform plate boundary</u>, two plates slide past each other, conserving the plates. Shallow-focus earthquakes are generated here.

The earth has experienced various geological processes, such as weathering and erosion of rocks, earthquakes, volcanic eruptions, mass extinction events, plate tectonic movements and many more. These continuous processes have configured the present shape of the earth's surface.

For example, the breaking up of the supercontinent Pangea divided into Laurasia and Gondwanaland and subsequently formed the present scenario. This separation of continents has taken place due to the convection current that generates in the mantle.

What is the internal energy of 2.00 mol of diatomic hydrogen gas (H2) at 35°C?
djyliett [7]
As you mentioned, we will use <span>Equipartition Theorem.
</span><span>H2 has 5 degrees of freedom; 3 translations and 2 rotation
</span>Therefore:
Internal energy = (5/2) nRT
You just substitute in the equation with the values of R and T and calculate the internal energy as follows:
Internal energy = (5/2) x 2 x <span>8.314 x 308 = 32.0089 x 10^3 J</span>

How do the current and coltage readings compare to before the wires were switched. Explain how to interpret them physically?
Blababa [14]
  • The potential difference between two locations in an electric circuit is measured using a voltmeter.
  • If the electricity passes through the voltmeter it shows deflection.

<h3>What is the purpose of a voltmeter?</h3>
  • A voltage meter, usually referred to as a voltmeter, is a device that measures the voltage, or potential difference, between two points in an electrical or electronic circuit.
  • volts is the unit of voltmeter(volts, millivolts, kilovolts)

<h3>What is the explanation for the link between current and voltage?</h3>
  • Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.

<h3>What is ohm's law in circuit?</h3>
  • V = IR, where V is voltage, I is current, and R is resistance, is known as Ohm's Law.
  • If you know the voltage of the battery in the circuit and how much resistance is in the circuit, you may use Ohm's Law to identify properties of a circuit, such as how much current is flowing through it.
