How long does a coffin last?
How long does a coffin last? Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind. But even that shell won’t last forever. A century in, the last of your bones will have collapsed […]
Why are scientific models limited?
Why are scientific models limited? The limitations of scientific modeling are emphasized by the fact that models generally are not complete representations. The Bohr atomic model, for example, describes the structure of atoms. Nor was it able to predict the energy levels for atoms with more than one electron. What is a conceptual model example? […]
Why can one put his her fingers beside the flame of a lit candle but not above the flame?
Why angular momentum of Earth is conserved?
Why angular momentum of Earth is conserved? Earth moves under the influence of the gravitational forces of all bodies in the Solar System. The energy and angular momentum of Earth are conserved, because the gravitational force is both conservative and central. Is angular momentum is a scalar? Angular momentum is a vector quantity that represents […]
What will increase fringe spacing?
What will increase fringe spacing? With a single slit the spacing increases with wavelength, though if you reduce the width of the slit enough, the number of fringes decreases and their size increases. How fringe benefits are calculated? Employers will calculate a fringe benefit rate to determine the percentage of an employee’s hourly wage relative […]
What are the 4 map projections?
What are the 4 map projections? Types of Map Projections Cylindrical Map Projections. Cylindrical map projections are one way of portraying the Earth. Conic Map Projections. Secondly, conic map projections include the equidistant conic projection, the Lambert conformal conic, and Albers conic. Azimuthal Map Projection. What is the best map of the world? The AuthaGraph […]
Why is red the hottest color?
Why is red the hottest color? The hotter a material is, the more average energy there is in the light it emits. Room temperature objects emit light of relatively low energy in the infrared. This is invisible to your eye. Objects heated in a flame can become red hot, and this is probably where you […]
Is nothing but the limit between maximum and minimum number?
Is nothing but the limit between maximum and minimum number? Minimum means the least you can do of something. For example, if the minimum amount of dollars you must pay for something is seven, then you cannot pay six dollars or less (you must pay at least seven). You can do more than the minimum, […]
