What caste are Chandra? As in South India, Bengal had lacked a clearly defined Kshatriya caste. The Pala, Sena, Chandra, and Varman dynasties and their descendants, who claimed the status of Kshatriya, “almost imperceptibly merged” with the Kayastha caste and became “the region’s surrogate Kshatriya or warrior class”. Is Chandra a female name? The name […]
Why do you always see the same face of the moon?
Why do you always see the same face of the moon? “The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every […]
What is the height of the ocean?
What is the height of the ocean? Its elevation is 400 meters (1,312 feet) below sea level. However, if depth were measured from the ocean floor, the Challenger Deep in the Pacific Ocean would be the lowest place on Earth. It measures 11,034 meters (36,200 feet) below sea level. Why is the sea not flat? […]
Does UV light destroy ozone?
Does UV light destroy ozone? How Ozone Destruction Works. UV light destroys ozone in water very quickly. The mechanism for destruction is dissociation, which occurs when UV energy breaks one of the oxygen bonds in an ozone molecule. What absorbs UV radiation? As sunlight passes through the atmosphere, all UVC and most UVB is absorbed […]
What is in a cosmic void?
What is in a cosmic void? Cosmic voids are vast spaces between filaments (the largest-scale structures in the universe), which contain very few or no galaxies. Voids are believed to have been formed by baryon acoustic oscillations in the Big Bang, collapses of mass followed by implosions of the compressed baryonic matter. Can true nothingness […]
What are the qualities of a proportional relationship?
What are the qualities of a proportional relationship? Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the “constant of proportionality”. What are four ways […]
What is the principle of the golden hour?
What is the principle of the golden hour? The golden hour is the first ’60 minutes’ following any injury or trauma. Prompt medical attention during this period can save one’s life. This period is very critical as the chances of survival depend on this window period. The golden hour is not just for traumatic situations […]
Can neutrons kill you?
Can neutrons kill you? The neutron burst, which is used as the primary destructive action of the warhead, is able to penetrate enemy armor more effectively than a conventional warhead, thus making it more lethal as a tactical weapon. What happens if you miss a radiation treatment? Missed Radiation Therapy Sessions Increase Risk of Cancer […]
What are 3 examples of metallic bonds?
What are 3 examples of metallic bonds? Examples of Metallic Bond Sodium (Na) Sodium has a lone electron in its outermost orbital, i.e., the 3s orbital. Magnesium (Mg) Magnesium has two electrons in its outermost shell, the 3s shell. Aluminum (Al) Aluminum has three valence electrons in the 3s orbital. How do metallic bonds form? […]
What is the difference between a qualitative and quantitative analysis?
What is the difference between a qualitative and quantitative analysis? Let’s differentiate between the two. Qualitative analysis fundamentally means to measure something by its quality rather than quantity. Quantitative analysis is the opposite; to measure by quantity rather than quality. When we do quantitative analysis, we are exploring facts, measures, numbers and percentages. Why quantitative […]
