Explanation:
An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device
Answer:
Energy, same
Explanation:
From the law of conservation of energy, it states that the total amount of energy is the same before and after any energy transformation. Energy can't be created nor destroyed but can only be transformed from one state to another. In the process of transformation, some minor losses may occur due to friction.
Evolution is a major part of human life. If we didn't have evolution, there would be no humans or organisms on earth. An example of evolution is humans. Humans evolved from apes after hundreds of thousands of years. If this didn't happen, there would be no human life. This is why evolution is a major part of human life on earth.
