Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because

reduces the value of an asset as a result of physical or functional factors over time. Therefore‚ the costs of the fixed assets should be recorded as an expense over their useful lives‚ since they depreciate and must be replaced once the end of their useful life is reached. Physical depreciation factors include wear and tear during use or from being exposed to such things as weather. Functional depreciation factors include obsolescence or changes in customer needs that cause the asset to no longer provide

Fortran Exercise #2: Coefficient Of Restitution 1. DEFINITION In this lab‚ we shall be studying the coefficient of restitution of a superball. The coefficient of restitution‚ COR‚ is the ratio of the bounce-back velocity to the original velocity of an object undergoing impact (such as a ball impacting the ground after being dropped from an initial height). Using the principle of the conservation of energy‚ the COR can be used to relate the bounce-back height to the original height of a ball dropped

Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are able
