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!
Answer:
1199 miles
Explanation:
1 hour 30 minutes = 1 + 30/60 = 1.5 hours
2 hours 15 minutes = 2 + 15/60 = 2.25 hours
The distance she flew in the 1st segment is:
1.5*345 = 517.5 miles
The distance she flew in the 2nd segment is:
2.25 * 345 = 776.25 miles
Since the 2nd segment is 45 degree with respect to the 1st segment, this means that she has flown
776.25 * cos(45) = 549 miles in-line with the 1st segment and
776.25* sin(45) = 549 miles perpendicular to the 1st segment:
So the distance from the end to her starting position is
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
