How fast does ultrasound travel through air? It is important in image resolution. Figure 7. Sound waves must have a medium to pass through. The speed at which a sound wave travels through a medium is called the propagation speed or velocity….C. The Basic Process in Greater Depth. Material Velocity (m/s) air 331 fat 1450 […]
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 […]
Which is more dangerous an earthquake or volcano?
Which is more dangerous an earthquake or volcano? Earthquakes can cause damage by shaking, tsunami’s, and landslides. Volcanoes can cause damage by ash flows, release of gases, mudflows, lava flows, and landslides. However, earthquakes can cause disasters without the help of a volcano. Earthquakes generate seismic waves that can release great energy. How do you […]
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 […]
How did the Welfare Reform Act of 1996 increase state power?
How did the Welfare Reform Act of 1996 increase state power? Welfare reform has undoubtedly greatly reduced reliance on welfare. Second, the Welfare Reform Act actually increased federal power over state welfare programs by requiring them to meet quotas or suffer severe financial penalties for failing to move enough welfare recipients off the rolls. What […]
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 […]
What is the pathway oxygen takes?
What is the pathway oxygen takes? During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the […]
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 […]
