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 […]
How do we know the nucleus is positive?
How do we know the nucleus is positive? Rutherford deduced that the atomic nucleus was positively charged because the alpha particles that he fired at the metal foils were positively charged, and like charges repel. In Rutherford’s experiments most of the alpha particles passed straight through the foil without being deflected. Is a nucleus positive? […]
What does the atomic mass tell you?
What does the atomic mass tell you? The atomic mass tells us the weight of protons and neutrons. How do you know how many electrons there are surrounding the nucleus of a particular atom? Why isn’t the atomic mass always a whole number? Atomic mass is never an integer number for several reasons: The atomic […]
What is going to happen in 2099?
What is going to happen in 2099? Artificial intelligence will move its influence beyond Earth’s limits to the entire Solar System, and then it will move on to other galaxies. Stars, planets, and meteors will be transformed into a structured matter capable of sustaining life. By 2099, machines will be capable of building computers the […]

Does Fire Insurance Pay arson? Arson is a crime while a fire due to a natural cause is not. One standard provision of fire insurance policies would be the exclusion of fires caused by arson. This means that when your property is damaged due to arson, you will not be entitled to collect any proceeds […]
Is heat or ice best for pinched nerve?
How do you thank someone for an extremely generous gift?
What is meant by the statement potential difference between A and B is 3v?
What is meant by the statement potential difference between A and B is 3v? Answer: If we say the potential difference between two points is 3 volt it does mean that 3 joule of work is done in moving a unit positive charge between those points. What is meant by saying that the potential difference […]
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 […]
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 […]
