Expenses for raw materials in a company-specific demarcation can represent revenues because the raw materials are used to create products that are then sold to customers. When the raw materials are transformed into finished goods, they add value to the products, which can be sold at a higher price than the cost of the raw materials. This price difference between the cost of raw materials and the selling price of the finished products represents the revenue generated from the use of those raw materials. Therefore, expenses for raw materials can be seen as an investment that leads to the generation of revenue for the company. **

The history of legitimate border demarcation between countries begins with the Treaty of Westphalia in 1648. This treaty marked the end of the Thirty Years' War and established the principle of territorial sovereignty, which laid the foundation for the modern nation-state system. The treaty recognized the right of each sovereign state to govern its territory and set the stage for the negotiation and establishment of borders between countries. Since then, the process of border demarcation has evolved through various treaties, agreements, and international law. **

The borders were also drawn to reflect the cultural, linguistic, and historical differences among the various German states, while also taking into account the territorial claims of the different rulers. Overall, the border demarcation aimed to create a stable and cohesive political entity out of the numerous German states. **

The volleyball serve may not go over the net due to various reasons such as improper technique, lack of power, or hitting the ball at the wrong angle.
