,The relationship between energy, work, and power can be stated as which of the following?
A. Work is required to convert energy into power.
B. Power is required to convert work into energy.
C. Power is measured in units of energy, and work is the transfer of power.
D. Energy is the ability to do work, work is the result of transferring energy, and power is the rate at
which the work is accomplished. - CORRECT ANSWER-Energy is the ability to do work, work is the
result of transferring energy, and power is the rate at which the work is accomplished.

Which of the following is TRUE about the relationship between potential and kinetic energy?
A. Potential energy converts to kinetic energy, but not the reverse
B. There is no relationship between potential and kinetic energy.
C. Kinetic energy converts to potential energy, but not the reverse.
D. Kinetic and potential energy may be converted in either direction - CORRECT ANSWER-Kinetic and
potential energy may be converted in either direction
Why is electricity distributed using extremely high voltages?
A. High-voltage electricity travels faster than lower-voltage electricity and can get from one side of
the country to the other in seconds.
B. For safety because the insulation on the electrical distribution lines is not as effective at lower
voltages.
C. To keep current as low as possible and reduce loss through the lines.
D. Higher voltages are easier to generate than lower voltages, so distributing them as a high voltage
reduces equipment and saves money. - CORRECT ANSWER-To keep current as low as possible and
reduce loss through the lines.
