What is the purpose of a ferrite bead? A ferrite bead is a passive device that filters high frequency noise energy over a broad frequency range. It becomes resistive over its intended frequency range and dissipates the noise energy in the form of heat. Is ferrite bead necessary? All good manufacturers provide ferrite beads whenever […]
What are two major uses of a classification system for abnormal behavior?
What are two major uses of a classification system for abnormal behavior? We need a classification system for abnormal behavior for two primary reasons. First, a classification system is useful to clinicians, who must match their clients’ problems with the form of intervention that is most likely to be effective. Second, a classification system must […]

How has the Kyoto Protocol been successful?
How has the Kyoto Protocol been successful? Successes of the Kyoto Protocol The Protocol has brought the world together to fight climate change leading to global collaborative efforts. Many nations have cut their GHG emissions, notably the European Union (Chavez, 2009). Was the Kyoto Protocol a failure? In 2001, the U.S. formally rejected the Kyoto […]
What force pulls the moon and Earth together?
What force pulls the moon and Earth together? Gravity Is Gravity present on moon? The Moon’s surface gravity is about 1/6th as powerful or about 1.6 meters per second per second. The Moon’s surface gravity is weaker because it is far less massive than Earth. You do not have the same weight on Earth as […]
What are the risks of using iodine-131?
What are the risks of using iodine-131? I-131 collects in the thyroid gland. People exposed to I-131, especially during childhood, may have an increased risk of thyroid disease, including thyroid cancer. Thyroid cancer is uncommon and is usually curable. Typically, it is a slow-growing cancer that is highly treatable. What percentage of an original sample […]
What is the strongest crystal structure?
What is the strongest crystal structure? Diamond is the hardest material known, defining the upper end of the 1-10 scale known as Moh’s hardness scale. Diamond cannot be melted; above 1700 °C it is converted to graphite, the more stable form of carbon. The diamond unit cell is face-centered cubic and contains eight carbon atoms. […]
How long does it take for carbon 14 to fully decay?
How long does it take for carbon 14 to fully decay? 5,730 years Will all of Carbon 14 eventually disappear? The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay. After 50,000 years, a fossil won’t have any radiocarbon left in it. Carbon-14 […]
How do you measure for built in bookshelves?
How do you measure for built in bookshelves? Measure the horizontal width of the wall space for the bookshelves. If the area is beside a window, door or other architectural feature, measure at the narrowest point, where the trim on the wall sticks farthest into the bookshelf space. What would you use to measure a […]
What type of reaction is Ca OH 2 Heat?
What type of reaction is Ca OH 2 Heat? Among widely recognizable exothermic reactions is the combustion of fuels (such as the reaction of methane with oxygen mentioned previously). The formation of slaked lime (calcium hydroxide, Ca(OH)2) when water is added to lime (CaO) is exothermic. How many different elements are involved in the chemical […]
