Long-run marginal cost is the slope of the long-run total cost curve. With TC (Q) =2 Q, the slope of the long-run total cost curve is 2, and thus MC (Q) = 2. Long-run mar-ginal cost also does not depend on Q. Its graph is the same horizontal line.This exercise illustrates a general point.ong-run marginal cost is the slope of the long-run total cost curve.

Combustion Definition. Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light. Combustion is considered an exergonic or exothermic chemical reaction. It is also known as burning.
What are the types of internal combustion engines? Internal combustion means just what it says: that fuel is burned inside the engine. In a car engine, gasoline is burned inside the engine, which ignites the fuel and releases energy that moves the car. There are also other methods of internal combustion, such as diesel engines and gas turbine engines. Internal combustion is an efficient system that requires a relatively small engine to create motion.
