Why is white light important? Light is one of the most important and versatile phenomena in nature. Like a courier, it can transfer information from one point to another. For visible light, the frequency determines the color and is related to the light’s wavelength (shorter wavelengths correspond to higher frequencies). … Is white light actually […]
Which is called soft coal?
Which is called soft coal? Bituminous coal, also called soft coal, the most abundant form of coal, intermediate in rank between subbituminous coal and anthracite according to the coal classification used in the United States and Canada. What type of coal is best for heating? Anthracite coal is the better choice when considering your next […]
Which era is called the Age of Mammals?
Which era is called the Age of Mammals? Cenozoic What is the oldest era? Paleozoic Era What do you call the present era? Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age. The Greenlandian, the oldest age of the Holocene (also known as the “lower Holocene”), […]
Which outcome is the main function of the light-dependent reactions of photosynthesis?
Which outcome is the main function of the light-dependent reactions of photosynthesis? The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules. The light-dependent reactions are depicted in (Figure). What […]
What are the five properties of alkalis?
What are the five properties of alkalis? Chemical Properties of Alkalis Alkalis react with Acids to form salt and water. This reaction is called neutralisation reaction. Alkalis react with ammonium salts to form salt, water and ammonia gas. Alkalis react with solution of metal salt to form another metal salt and hydroxide. What are the […]
What is difference between preventive and periodic maintenance?
What is difference between preventive and periodic maintenance? The main difference between the two is that preventive maintenance is scheduled at regular intervals while predictive maintenance is scheduled as needed (based on asset conditions). These costs are often acceptable to organizations that have already successfully implemented a preventive maintenance program. What are the benefits of […]
How do you describe a theory?
How do you describe a theory? A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. How […]
What are the 5 factors of evolution?
What are the 5 factors of evolution? Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture. All evolutionary biologists agree on the first three of these forces, although there have been disputes at times about the relative importance of each force. What is the main cause […]
WHY BE is not noble gas?
What will happen if two hydrogen atoms combine?
What will happen if two hydrogen atoms combine? Thus, two Hydrogen atoms combine to form a Hydrogen molecule. The number of protons in the atomic nucleus is equal to the number of electrons revolving around that nucleus. This means that the positive electric charge is balanced by the negative. The atom is therefore electrically neutral. […]
