<em>A burning candle</em> is a great example.

First the wax melts (physical change).

Then when the melted wax is hot enough, it combines with oxygen in the air, forms carbon monoxide and carbon dioxide, and drifts away as hot gases (chemical change).

PilotLPTM [1.2K]

Answer:

Newton's laws of motion and gravity explained Earth's annual journey around the Sun. Earth would move straight forward through the universe, but the Sun exerts a constant pull on our planet. This force bends Earth's path toward the Sun, pulling the planet into an elliptical (almost circular) orbit.

How does a generator use the effect you noticed in the pickup coil to generate electrical energy? What energy transformations ar
Oksana_A [137]

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.
