An arched back in a handstand is when the back is not straight and instead curves inward, creating a concave shape. This can happen when the shoulders are not properly aligned, causing the lower back to arch excessively. It can also occur when there is a lack of core strength and control. An arched back in a handstand can lead to poor alignment, decreased stability, and increased risk of injury. It is important to maintain a straight, neutral spine in a handstand to ensure proper form and safety. **

A split in an arched back refers to a condition where the muscles and tissues in the back become strained or torn, causing a separation or split in the arch of the back. This can be caused by overexertion, poor posture, or sudden movements that put excessive strain on the back muscles. A split in an arched back can be quite painful and may require rest, physical therapy, or other treatments to heal properly. It is important to seek medical attention if you suspect you have a split in your arched back to prevent further injury. **

There is no full employment in a free market economy because of various factors such as technological advancements, changes in consumer preferences, and fluctuations in demand for goods and services. Additionally, there is always a certain level of frictional and structural unemployment as people transition between jobs or industries. Furthermore, the free market economy allows for businesses to make decisions based on their own interests, which can lead to fluctuations in employment levels. Overall, the dynamic nature of the free market economy means that full employment is not always achievable. **

Market share refers to the percentage of total sales in a market that a company holds. It is calculated by dividing a company's sales by the total market sales. Market growth, on the other hand, refers to the increase in the total size or value of a market over a specific period of time. It is often measured as a percentage increase in market sales or revenue. Both market share and market growth are important metrics for businesses to track in order to assess their performance and competitiveness in the market. **

In a market economy, various market forms exist, including perfect competition, monopolistic competition, oligopoly, and monopoly. Perfect competition is characterized by many small firms selling identical products, with no single firm having market power. Monopolistic competition involves many firms selling similar but slightly differentiated products, allowing for some degree of market power. Oligopoly consists of a few large firms dominating the market, leading to interdependence among them. Monopoly occurs when a single firm controls the entire market, giving it significant market power. **

The car market is not a perfect competition market. Perfect competition markets are characterized by many small firms producing identical products, easy entry and exit of firms, perfect information, and no market power for any individual firm. In the car market, there are a few large firms that dominate the industry, and they have significant market power to influence prices and competition. Additionally, the products offered by different car manufacturers are not identical, and there are barriers to entry for new firms due to high capital requirements and technological expertise. Therefore, the car market does not meet the criteria for perfect competition. **
