Rubbing two surfaces together creates friction, which expresses itself as heat. It is possible that static electricity will also be created (probable, actually), but there may or may not be a visible result of the buildup and/or neutralization of the charge (and usually there isn't). The force of friction derives from the electromagnetic forces of atoms and their electrons, so it is atomic and molecular forces that give rise to the phenomenon of friction. There are a lot of variables involved when two surfaces come into contact and move past one another. A link to the Wikipedia post on friction is provided. Heat is studied under the heading thermodynamics, and you'll need to fasten your seatbelt when you get ready to surf over there. An additional link is provided.
When two objects are rubbed together the force that is trying to stop you from moveing them is called Friction, friction produces heat which is why you can warm your hands by rubbing them together.
they become static electricity because their charges are different so they don't repel from each other.
friction?
Friction meaning heat for a+.
Friction will be made when two surfaces are rubbed together.
Friction is produced with two surfaces rub against each other.

The significance of studies contain a great many different things. This significance includes being more educated and being able to change things.
A liquid that can dissolve things is a solvent. The thing being dissolved is a solute.
backdrafting <><><> Incomplete brning of the gas, resulting in carbon monoxide being produced.
there is no answer no pencils can be made in a sec Machine made pencils can be produced at more than one per second. Look up a pencil manufacturer. Across the world probably hundreds of pencils a second are being produced.
Air travels through the whistle rubbing against the sides of the whistle than being forced out of the smaller opening at the front. The friction of air against the sides of the whistle is what makes the noise.
Water and Sun.
All things that are discontinued are no longer being produced.
Mechanical energy is being converted to thermal energy as the scout rubs the sticks together, creating friction that generates heat to ignite the fire.
They are being produced.
proteins stop being produced due to lack of DNA function
Heat's produced by many objects, like heaters, lights, engined, the sun, etc. All of that comes from particles rubbing together, which creates friction, which creates heat. I'm not sure how the process starts, but when particles get hot, they [move around] more, which creates the heat. I not 100% about this, so please correct me if I'm wrong :)
Caring, kissing, holding hands, telling random things, going out together, and enjoy to be together.
Because they will contract as they cool and that will pull the things being connected closer together.
Sometimes yes, sometimes no. Depends on the site and whether the item in question is still being produced or not.
There is no such thing as a "non-living" cell. If you are referring to living things being produces by non-living sources that would be abiogenesis.
set amount of something being produced
1. rubbing your hands together to keep warm in winter 2. the parts of a car engine rubbing together causes it to overheat sometimes 3. rubbing sticks together to make fire (it takes about two horus, but the stick gets hot)
