the crest of the other. Two wave trains of light from a double slit produce interference, an effect that is visible on a screen as a pattern of alternating dark and light bands caused by intensification and extinction at points at which the waves are in phase and out of phase, ...
concentration of the substance, and if the constant of proportionality isD,thenj= −D(dc/dx);dc/dxis the rate of change of concentration in the directionx,and the minus sign indicates the flow is from higher to lower concentration.Dis called thediffusivityand governs the rate of diffusion....
Irritated: His constant questions were irritating. Furry: The puppy had a furry coat. Chilly: The breeze was chilly in the evening. Peaceful: The garden was a peaceful retreat. Adorable: The baby’s laughter was adorable. Graceful: The dancer’s movements were graceful. Radiant: Her smile wa...
An example of a first-order reaction is: [A] --> [B] + [C] The rate is dependent on the concentration of one reactant, A. The rate equation can be expressed as: rate = k[A]m If at stable environmental conditions, the following concentrations and rates of reaction are: Experiment ...

Beyond that, it also reflects an organism's ability to reproduce well. It isn't enough for a tree to create a bunch of seeds. Those seeds need the ability to end up in fertile soil with enough resources to sprout and grow. Fitness and natural selection were first explained in detail by...
Spring constant (symbolized as k) is a proportionality constant associated with the stiffness of the spring. It is also known as the spring stiffness constant and has an SI unit of newton per meter (N/m). Its value varies depending on the type of spring or material. The larger its value...
This article reviews two recently established methods to compute sensitivities of some core parameters to basic nuclear data. First, perturbation theory offers an efficient way to compute sensitivities to nuclear parameters in continuous energy transport
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of th
Hydrolysis, in chemistry and physiology, a double decomposition reaction with water as one of the reactants. The other reactants, and the products of hydrolysis, may be neutral molecules, as in most hydrolyses involving organic compounds, or ionic molecu
