The diagram shows a simple electric generator. The needle that measures electric current will move back and forth between a largely positive and a large negative value.
- What is an electric generator?
- An electric generator is physically equivalent to an electric motor. but it converts mechanical energy into electrical energy.
- The electrical field generated is dependent on the inclination of the wire with respect to magnetic field lines, and this inclination changes over time,
because of that she will experience a varying electrical field, and thus a varying electric current will be zero.
The maximum positive value will occur when the wire is perpendicular to the magnetic field lines after one-fourth of rotation, and then zero.
Hence option C is correct.

Explanation:
Answer:
Según la actitud del hablante las oraciones se clasifican en enunciativas, interrogativas, etc. ... adverbios o expresiones que complementan a toda la oración (COr): ojalá, quizá.
Explanation:
M= ?
g=9.8 m/s (2)
h=20 m
Eg=362,600 J
Eg/mg
362,600 J/9.8 m/s (2) x 20 m
=1,850 m
Your answer is electricity, light and magnetism. They can be determined usinf elecromagnetic radioation.

Even the energy can't be detected by our eyes, there are a lot of measurement instruments that can measure infrared (IR), gamma rays, radio or X-rays or ultraviolet (UV)</span>
