Electric Heating systems use electricity as a source of heat.
<u>Explanation:
</u>
Each heater consists of an electric resistor, which the heating element in it. The process involved is Joule Heating. It is the phenomenon in which, passage of electric current produces heat. Heat is generated when the electrons from the current and the positive ions of the conductor start interaction.
The presence of voltage difference makes an electric fields, which in turn accelerates the charges present in the conductors. When they collide with ions of conductor, heat gets generated, and emitted out, which we use for heating purposes.
Gravity is a non-contact force.
Answer:
truck 1 has the most velocity
Explanation:
Because it weights less which means it faster and yea
Answer:
The law of conservation of momentum states that the total momentum of interacting objects does not <u>change</u>. This means the total momentum <u>before</u><u> </u>a collision or explosion is equal to the total momentum <u>after</u><u> </u>a collision or explosion.
in a state of mind that prevents normal perception, behavior, or social interaction; seriously mentally il
