Why does stored energy increase as separation increases? If the capacitor is now disconnected, and its capacitance is changed by increasing the distance between the plates, its energy must increase since work is being done by moving charge under the influence of an electrical field. Why capacitance does not depend on voltage? 1 Answer. In […]
Is water made of pee?
Is water made of pee? Urine is about 95% water. It is not completely sterile of microorganisms, as many sources incorrectly state. But it doesn’t contain any of the harmful microbes that can make you immediately sick—such as those you might ingest from contaminated wilderness water, and which are generally transferred through feces instead. Do […]

Field Magnet – could be a permanent magnet or an electromagnet. An Armature or rotor. Commutator. Brushes. Axle. Are electric motors used today? They operate using principles of […]
What is another name for the extrusive rock?
What is another name for the extrusive rock? volcanic rocks What are the classification of igneous rock? As has already been described, igneous rocks are classified into four categories, based on either their chemistry or their mineral composition: felsic, intermediate, mafic, and ultramafic. What are some examples of an igneous rock? These rocks include: andesite, […]
What is the relationship between vapor pressure and temperature?
What is the relationship between vapor pressure and temperature? The vapor pressure of a liquid varies with its temperature, as the following graph shows for water. The line on the graph shows the boiling temperature for water. As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases […]
Are COVID-19 vaccines safe?
Are COVID-19 vaccines safe? COVID-19 vaccines are safe and effective. Millions of people in the United States have received COVID-19 vaccines under the most intense safety monitoring in U.S. history. CDC recommends you get a COVID-19 vaccine as soon as you are eligible. Is the Covid vaccine safe long term? Because COVID-19 vaccines clinical trials […]
What is Schottky defect with diagram?
What is Schottky defect with diagram? A Schottky defect is an excitation of the site occupations in a crystal lattice leading to point defects named after Walter H. In ionic crystals, this defect forms when oppositely charged ions leave their lattice sites and become incorporated for instance at the surface, creating oppositely charged vacancies. Why […]
What happens in the upper mantle?
What happens in the upper mantle? The upper mantle begins just beneath the crust and ends at the top of the lower mantle. The upper mantle causes the tectonic plates to move. Crust and mantle are distinguished by composition while the lithosphere and asthenosphere are defined by a change in mechanical properties. Why is the […]
Do you pinch skin for IM injection?
Do you pinch skin for IM injection? Insert needle at an 45o angle to the skin. Pinch up on SQ tissue to prevent injecting into muscle. Aspiration before injection is not required. What size needle is used for a subcutaneous injection? 5/8″ needle What are the 3 types of injections? The three main types of […]
What methods are used in primary treatment of wastewater?
What methods are used in primary treatment of wastewater? There are three basic biological treatment methods: the trickling filter, the activated sludge process, and the oxidation pond. A fourth, less common method is the rotating biological contacter. What is the main goal of primary treatment in a modern sewage treatment plant? The objective of primary […]
