What is the formula for calculating core area? The equation you will need to use is: A = L x W. This answer will be in millimeters squared, and effective core area is always reported in millimeters squared (mm^2), so you have no factor conversion to make here. How do you find the cross sectional […]
Is electricity the movement of electrons?
Is electricity the movement of electrons? Electricity is the movement of electrons between atoms. Why do electrons move from negative to positive? A: Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets […]
What is meant by Vsepr theory?
What is meant by Vsepr theory? The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. Repulsion between these pairs of electrons can be minimized by arranging them so that they point in opposite directions. Why is Vsepr […]
How long does it take to settle a rear end collision?
How long does it take to settle a rear end collision? After reaching a settlement agreement, you might be wondering how long it will take until you receive your compensation. For cases with minor crashes and minor damages, cases typically take 30 to 90 days. If your case goes to court, it could take years […]
What vehicles must stop at all railroad crossings NY DMV?
What vehicles must stop at all railroad crossings NY DMV? Most buses and some trucks must stop at railroad crossings. (See “Railroad Crossing Signals”.) Flashing red lights, lowered crossing gates and/or a bell at a railroad crossing indicate that you must stop, at least 15 feet (5 m) from the tracks. What is the appropriate […]
What are the mixtures that Cannot be separated?
What are the mixtures that Cannot be separated? An element is a pure substance that cannot be separated into simpler substances by chemical or physical means. There are about 117 elements. What jobs use separation techniques? Familiar professions that use separation techniques Chefs – decanting, sieving, filtering. Dentists – safe disposal of mercury fillings (filtering). […]
Is 25 miles per hour wind fast?
What is the formula of starch?
What is the formula of starch? The basic chemical formula of the starch molecule is (C6H10O5)n. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form. What is the structure and function of starch? Starch is the form […]
What will happen if we lose mangroves?
What will happen if we lose mangroves? Research shows that mangroves play a key role in carbon sequestration – removing about 1,000 tonnes of carbon per hectare – over thousands of years. The loss of mangroves contributes to nearly one-fifth of global emissions from deforestation. Climate change also affects their survival. How many mangroves are […]
How many times do pulsars spin?
How many times do pulsars spin? The fastest known millisecond pulsars can rotate more than 700 times per second. How do pulsars die? Since the light energy escapes, the production of the energy beam robs energy from the pulsar, so the pulsar’s rotation slows down (angular momentum does slowly decrease). Eventually, the pulsar dies away […]
