What is the purpose of thin layer chromatography? TLC is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography can be used to monitor the progress of a reaction, identify compounds present in a given mixture, and determine the purity of a substance. What are the two major uses of thin layer chromatography? The […]
What are the two types of kinetic friction?
What are the two types of kinetic friction? In general, the friction is of the following two types: (1) Static friction. It is the friction, experienced by a body, when at rest. (2) Dynamic friction. It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. […]
Do you weigh more on a full moon?
What color bends most during refraction?
What color bends most during refraction? violet light What are two effects of refraction? The major effects of refraction of lights are: Bending of light. Change in wavelength of light. Splitting of light rays if it is polychromatic in nature. Does speed of light change during refraction? When light travels from one medium to another, […]
What are the negatives of biofuels?
What are the negatives of biofuels? Disadvantages of Biofuels High Cost of Production. Even with all the benefits associated with biofuels, they are quite expensive to produce in the current market. Monoculture. Use of Fertilizers. Shortage of Food. Industrial Pollution. Water Use. Future Rise in Price. Changes in Land Use. What are advantages and disadvantages […]
What is the average force of impact?
What is the average force of impact? The most straightforward way to approach the concept of average force is to multiply the constant mass times the average acceleration, and in that approach the average force is an average over time. Another approach that is valuable for assessing the impact force in high speed collisions is […]
What is Hertz formula?
What happens to Wavefunctions as n increases?
What happens to Wavefunctions as n increases? Note that as n increased, the energy of the wavefunction increases (Equation 3.5. 12) and both the number of nodes and antinodes increase and the frequency of oscillation of the wavefunction increases. When the particle strikes the wall of the well it bounces off completely true or false? […]
What is a simple food chain?
What is a simple food chain? A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain. What is bioaccumulation […]
How do humans interact with the atmosphere?
How do humans interact with the atmosphere? There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth’s atmosphere, ocean and land surface to increase … […]
