Does tennis ball have to bounce? The ball must first bounce out before the player can touch it. Also, a player loses a point if his/her clothing makes contact with the ball, or his/her hand that is holding the racket touches the ball during a shot. Therefore, oddly enough, a player who hits his/her opponent […]
Why is white light important?
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 […]
Are protons positive or negative?
Are protons positive or negative? Protons and Electrons A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain. […]
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 […]
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 […]
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. […]
