Why is de Broglie relationship is only for microscopic objects? The wave nature of matter, however, has no significance for objects of ordinary size because wavelength of the wave associated with them is too small to be detected. Thus, de-Broglie concept is significant only for sub-microscopic objects in the range of atoms, molecules or smaller […]
What are the 3 types of serves in volleyball?
What are the 3 types of serves in volleyball? For competitive volleyball, there are three main types of overhand serves: the floater, the topspin, and the jump serve. Try them all to find out which one suits you best, but keep in mind that you will want to be somewhat proficient in all three. What […]
What is the main purpose of using machine?
What is the main purpose of using machine? The basic purpose for which most simple machines are designed is to reduce the effort (force) required to perform a simple task. To achieve this, the force applied must act over a longer distance or period of time resulting in the same amount of work being performed […]
Can walk on Mars?
Can walk on Mars? But how will astronauts walk on Mars, where the gravity is a third of Earth’s? Volunteers walked on force-monitoring platforms while the aircraft flew up and down to recreate martian gravity. The results showed that the ideal walking speed on Mars will be only a little more than half of the […]
How many neutrons does 19 9 F?
How many neutrons does 19 9 F? 10 neutrons Is fluorine-19 an ion? According to the periodic tale, fluorine, F, has an atomic number of 19. We can conclude that fluorine gained an electron to reach a stable octet configuration, and because it has an extra electron it is now called a fluorine ion. Why […]
What can be the cause of weakening muscles and kidney function?
What can be the cause of weakening muscles and kidney function? When muscle is damaged, a protein called myoglobin is released into the bloodstream. It is then filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells. Rhabdomyolysis may be caused by injury or any other condition […]
Is F2 a single or double bond?
Why do we use copper and not silver or graphite for electrical wiring in our houses give a reason for each?
Why do we use copper and not silver or graphite for electrical wiring in our houses give a reason for each? Unlike silver which in its natural state is a metal like copper, the form of graphite with very low resistivity to compare with copper is graphene. Technically its not a metal which can be […]
What causes trichromatic vision?
What causes trichromatic vision? The normal explanation of trichromacy is that the organism’s retina contains three types of color receptors (called cone cells in vertebrates) with different absorption spectra. In actuality the number of such receptor types may be greater than three, since different types may be active at different light intensities. What causes Tetrachromatic […]
Why is water called a universal solution?
Why is water called a universal solution? Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the “universal solvent” because it dissolves more substances than any other liquid. This allows the water molecule to become attracted to many other different types […]
