What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
What happens if a hairline fracture is untreated?
What happens if a hairline fracture is untreated? When a bone fracture is untreated, it can result in either a nonunion or a delayed union. In the former case, the bone doesn’t heal at all, which means that it will remain broken. As a result, swelling, tenderness, and pain will continue to worsen over time. […]
What is the distance between two contour lines called?
What is the distance between two contour lines called? The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called […]
Which of the following would be the best soil for gardening 2 points?
What is the SI base unit of mass?
What is the SI base unit of mass? kilogram (kg) What is the purpose of SI base units? The SI base units are a fundamental part of modern metrology, and thus part of the foundation of modern science and technology. The SI base units form a set of mutually independent dimensions as required by dimensional […]
What is the relationship between volume and pressure for a gas?
What is the relationship between volume and pressure for a gas? It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured. Are volume and temperature directly proportional? The volume of a […]
What is the direction of the induced current in the circular loop of radius r?
What is the direction of the induced current in the circular loop of radius r? The direction of induced current in the circular loop will be clockwise or anti-clockwise depending upon the direction of current in the straight wire. The amount of induced current will be decided by the velocity with which the loop is […]
Is plastic or wood a better insulator?
Is plastic or wood a better insulator? Metal is a good conductor of heat, while wood and plastic are good insulators. A conductor transfers thermal energy (heat) well, while an insulator does not transfer thermal energy (heat) well. What is the warmest insulation for jackets? Loftier (or puffier, if you will) materials consist of more […]
What is differentiation strategy example?
What is differentiation strategy example? What is a differentiation strategy? As opposed to cost leadership, the differentiation strategy allows companies to take on an innovative approach for their products, and charge premium prices for it. For example, Starbucks goes beyond selling coffee by providing a unique coffee experience in their coffeehouses. What is the formula […]
What causes resistance in a wire?
What causes resistance in a wire? The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. […]
