In a natural gas power plant, natural gas is burned to heat steam, which turns a turbine. What energy conversion is happening in
Irina18 [472]
<h2>Hello!</h2>

The answer is A. Chemical energy to heat energy to kinetic energy to electrical energy.

<h2>Why?</h2>

Let's check the energy conversion given in the statement:

Chemical energy: Chemical energy is usually obtained from a natural resource combustion. For this particular case is the result of natural gas combustion.

Heat energy: Heat energy comes from chemical reactions such as natural gas combustions.

Kinetic energy: Kinetic energy is obtained by turbines transforming the pressurized steam on mechanical movement. Turbines are formed by a turbine that absorbs the heat energy to do mechanical work and transmit it to an output rotating shaft.

Electrical energy: Electrical energy is generated by gas turbines when the rotating output shaft is connected to an electrical generator. Electrical generators use mechanical energy to generate electrical energy by using electromagnetic induction. Electrical generators are basically formed by a rotor and a stator.

Have a nice day!

The speed of an object undergoing constant acceleration increased from 8.0 meters per second to 16.0 meters per second in 10. Se
saw5 [17]

v₀ = initial speed of the object = 8 meter/second

v = final speed of the object = 16 meter/second

t = time taken to increase the speed = 10 seconds

d = distance traveled by the object in the given time duration = ?

using the kinematics equation

d = (v + v₀) t/2

inserting the above values in the above equation

d = (16 + 8) (10)/2

d = 120 meter

Answer:

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Explanation:

The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.

Thus, the correction for this question is "D"

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
