Answer:
An electric motor converts electrical energy into mechanical energy. The process is as follows:
D. When current flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.
It probably also has a nineth of the speed, so it's 81 earth years. If they had the same speed, it would be 9 earth years. Probably the first one is more accurate :-??
The types of chemical reactions are as follows:
- Combination reactions
- Decomposition reactions
- Double decomposition
- Thermal dissociation
- Redox reactions
<h3>What the are the types of reactions?</h3>
Chemical reactions are changes in which new substances are formed.
The types of chemical reactions are as follows:
- Combination reactions - these are reactions in which two or more substances combine to form a single compound
- Decomposition reactions - these are reactions in which a larger compound splits into smaller substances
- Displacement reactions - these are reactions in which one element or radical replaces another in a compound
- Double decomposition - these are reactions in which two substances exchange their radicals to form new compounds.
- Thermal dissociation - these reactions involves heating compounds to split them into smaller substances.
- Redox reactions - these are reactions in which oxidation and reduction reactions occur simultaneously.
In conclusion, chemical reactions produce new substances.

The normal force is always (underline, bold) is always perpendicular to the surface an object is sitting on. If the object is on an inclined plane, then the normal will not be vertical but it will be perpendicular to the angle of the incline.
The diagram below (left) shows a normal force (GH) that is not vertical, but it is perpendicular to the surface. The object on the right is the more usual normal a mass on a table top.
The vertical line on the right is the normal and it points up.
