Which of the following statements about vortex rings is true? Vortex rings are two-dimensional structures. Vortex rings move in a straight line without changing shape. Vortex rings are formed when a fluid is ejected into another fluid with a different density Vortex rings are only observed in liquids and not in gases. Explanation:These circular rings of gas, primarily water vapour, emerge from a newly formed pit crater on the volcanoโs north side.The phenomenon occurs when gas is rapidly released through a nearly circular vent, forming perfectly circular rings.Volcanic vortex rings were first observed at Etna in 1724 and have since been documented at various volcanoes worldwide.They can linger in the air for up to 10 minutes but may disintegrate quickly in windy conditions.Vortex rings are toroidal vortices that form when a fluid is ejected into another fluid with a different density. They are three-dimensional structures and can move through both liquids and gases. They are characterized by a rolling motion that maintains their shape as they move through the surrounding fluid. 2 / 5 2. Which one of the following statements best describes the term โCryogenicsโ? It is the study of how to achieve and maintain high temperatures for industrial combustion processes. It focuses on the development of refrigeration techniques that operate at temperatures just below the freezing point of water. It is primarily concerned with the study of biological organisms at temperatures slightly above freezing. It is the science that addresses the production and effects of very low temperatures. Explanation:Cryogenics is the branch of physics and engineering that studies the behavior of materials and systems at extremely low temperatures, typically below -150ยฐC (-238ยฐF) or 123K (Kelvin).ย This field focuses on understanding how these low temperatures affect various substances and their properties and developing methods to produce, maintain, and apply such low temperatures in practical applications.ย While refrigeration involves cooling materials to temperatures below the freezing point of water (0ยฐC or 273K), cryogenics focuses on much lower temperatures beyond what refrigeration typically achieves. 3 / 5 3.Which one of the following statements best describes the โcore inflationโ and its relevance in economic policy formulation? Core inflation is a measure of inflation that includes all items in the consumer price index (CPI), including those with volatile prices such as food and energy, to provide a comprehensive overview of inflationary trends. Core inflation is the change in the costs of goods and services, including seasonal elements such as food and energy, and is primarily used to assess short-term inflationary rise and guide immediate fiscal policy adjustments. Core inflation is a measure of inflation that excludes items having volatile prices, such as fuel and food, from the price index being used, to assess the underlying trend of prices and guide long-term economic strategies. Core inflation represents the immediate impact of monetary policy measures on the price level of luxury goods and services, excluding necessities, to determine the effectiveness of central bank interventions. Explanation:ย Core inflation is an essential metric that policymakers use to understand the fundamental drivers of inflation by removing the effects of temporary price fluctuations.ย By excluding volatile items like food and energy, core inflation provides a more stable measure of inflation, helping policymakers design and implement appropriate economic strategies for sustainable growth and price stability in the long term. 4 / 5 4. The term โDoxingโ, seen in the news recently, refers to: The process of fixing documents online to ensure data privacy and prevent identity theft. A legal method of sharing someone personal information with their consent for security purposes. The act of publicly revealing identifying information about someone online without their consent. The act of repairing or removing false personal information about individuals from the internet. Explanation:ย Doxing (sometimes spelled as "doxxing") is a malicious practice where an individual's personal information, such as their name, address, phone number, or other private details, is shared online without their consent.ย This can result in harassment, threats, or other negative consequences for the targeted person. Doxing is often associated with cyberbullying and online vigilantism, and it raises significant concerns regarding privacy and online safety. 5 / 5 5.
