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 […]

Is there a measure of sharpness? There is no unit of sharpness but instruments are available to measure it. Those instruments provide accurate results with high precision. What is the sharpest knife in the world? Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 […]

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 […]

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 […]

Does high spin speed damage clothes? Myth: Higher spin speeds will ruin your clothes! Busted: No! Higher spin speeds will not ruin your clothes when you use the appropriate settings. High spin speeds are ideal for cottons, bulky items such as towels and bedding and denim. Can you rinse clothes in a spin dryer? You […]

What will happen in 600 million years? Total solar eclipses occur because the moon and the sun have the same apparent size in Earth’s sky — the sun is about 400 times wider than the moon, but the moon is about 400 times closer. … Can the entire earth see each solar eclipse? Image courtesy […]

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 […]

Is it bad to be in peak heart rate zone? Going higher than your maximum heart rate for long periods of time could be dangerous for your health. That’s especially true if you’re new to exercise. Do you burn fat in peak heart rate zone? The ‘fat burning zone’ is where you are working out […]

How do you know if starter motor is bad? What are common bad starter symptoms? Something sounds off. One of the symptoms of a bad starter is a clicking noise when you turn the key or push the start button. You’ve got lights but no action. Your engine won’t crank. Smoke is coming from your […]

What is the danger of replacing a circuit breaker or fuse with a larger rating? Since all fit the same socket, there is always the danger of replacing one fuse with a higher amperage than is safe. The higher-rated fuse will allow more current to flow than the wires can safely handle, causing overheating and […]
