What are the advantages of generalized coordinates?
What are the advantages of generalized coordinates? The major advantage of using generalized coordinates is that they can be chosen to be perpendicular to a corresponding constraint force, and therefore that specific constraint force does no work for motion along that generalized coordinate. What is rigid body How many generalized coordinates will have to be […]
What are the odds of getting West Nile?
What are the odds of getting West Nile? The odds of getting the most severe forms of West Nile disease are about one in 150. What are the long term side effects of West Nile virus? The most common long-term effects are depression, tremors, fatigue, memory problems, extremity weakness, word-finding difficulty and headaches. Since WNV […]
Can eyes affect the brain?
Can eyes affect the brain? They also noted that vision had a stronger influence on brain function than the reverse. This suggests that maintaining good vision health by having regular check-ups and addressing problems like cataracts, glaucoma, and age-related macular degeneration may help keep your brain healthy as you age. Can head trauma cause eye […]
What is the difference between force and energy?
What are the limitations of valence bond theory?
What are the limitations of valence bond theory? Limitations of Valence Bond Theory The theory assumes that electrons are localized in specific areas. It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds. No distinction between weak and strong ligands. Why MOT is preferred over VBT? molecular orbital theory […]
Why some elements are reactive?
Why some elements are reactive? The number of electrons in the outermost shell of an atom determines its reactivity. Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell. Is S or O more […]
How do you know if starter motor is bad?
Which statement best describes what occurs during a chemical reaction?
Which statement best describes what occurs during a chemical reaction? During a chemical reaction both the identity and the properties of a substance change. Chemical reaction between two substances occurs to form a new substance which is completely different. Therefore, it has different appearance and physical state as well as the chemical properties. Which statement […]
