Answer:
Movement of Electrons in opposite direction of the rotation of the pickup coil leads to the direction of Electrical energy ( Alternating current ).
Explanation:
For a Generator to generate electricity, Electrons that is found in the rotating coil of the Generator will experience some sort of force that makes them to start moving in a direction that is perpendicular to the direction of the rotating/pickup coil found in the Generator.
The conversion of mechanical energy (Rotation of the pickup coil ) to electrical energy takes place in the Generator
The generator makes an alternating current because electrons move in opposite direction of the rotating coil
In other to generate a Direct current using a generator we have to replace the slip rings with commutator.
Answer:
.
Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy.
nuclear fission reactors include the possibility of radiation-releasing nuclear accidents, the problems of radioactive waste disposal, and the possibility of contributing to nuclear weapon proliferation
The <u><em>voltage</em></u> at the input to the hair dryer is
V = (current) · (resistance)
V = (15 A) · (8 Ω)
<em>V = 120 volts</em>
<em>__________________________________</em>
The <em><u>power</u></em> dissipated by the hair dryer is
P = (current)²· (resistance)
P = (15 A)² · (8 Ω)
<em>P = 1800 watts </em>

Have in mind: Energy is always conserved and, (...) be transferred between objects or systems, from one form to another.
Hence, the true relation is C, when a system gains kinetic energy, it loses potential energy.
Think about this,
K + P = constant
If K increases, then P need to decreases to holds the above relation.
The correct answer is answer choice B.
