Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

The center hole through the ferrule is large enough to fit the Fiber cladding (which is usually 125um after fiber coating stripped off) but tight enough to hold the fiber in a fixed position without any further moving. Standard bore diameters are 126 +1/-0 um for single mode connectors and 127 +2/-0 um for multimode connectors. Because of fiber cladding diameter’s variation from manufacturing‚ some fiber

concentration of the absorbing species‚ . When this information is graphed with absorbance on the y axis and at different points of concentration on the x axis‚ the best fit line equation will have a slope that is equal to Ԑ‚ giving us molar absorptivity (1). Then we can use the value of Ԑ to determine the concentration of [K2Cr2O7]‚ by taking the absorbance ratings and dividing them by Ԑ. Determining the order of reaction for a reactant‚ in this case K2Cr2O7‚ must be done experimentally (2). This is

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress
