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 […]
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 […]
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 […]
What is the significance of knowing strengths and weaknesses of a research work?
What is the significance of knowing strengths and weaknesses of a research work? Knowing your weaknesses allows you to understand how you can work around them. Strengths and weaknesses are part of being self-aware. When you know your strengths and weaknesses, you can create a development strategy that focuses on your specific development needs. What […]
Why is there vacuum above the level of mercury in a mercury barometer?
Why is there vacuum above the level of mercury in a mercury barometer? The top of the barometer is filled with nothing (vacuum) because the mercury must have the space to expand and contract without any other force affecting it; a gas or liquid in the top would have its own pressure against the mercury […]
How long can you live after radiation therapy?
How long can you live after radiation therapy? For most people, the cancer experience doesn’t end on the last day of radiation therapy. Radiation therapy usually does not have an immediate effect, and it could take days, weeks or months to see any change in the cancer. The cancer cells may then keep dying for […]
What is the difference between primary and secondary winding?
What is the difference between primary and secondary winding? The primary winding is the coil that draws power from the source. The secondary winding is the coil that delivers the energy at the transformed or changed voltage to the load. Usually, these two coils are subdivided into several coils in order to reduce the creation […]
What is the formula for calculating core area?
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 […]
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 […]
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 […]
