What is the tension in the string in the figure? T = W - FB where T is the weightof the Al and FB buoyant force due to thealcohol T = ρAl V g - ρE V g =(ρAl - ρE) V g =(ρAl - ρE) * 10E-4 *9.8 converting the volume to m3 Using 2700 for the density of Al and 790 for the density ofethyl alcohol T = 1910 * 10E-4 * 9.8 = 1.87 N A wood block with a density of 700 floats in water. What is the distance from the top of the block to the water if the water is fresh? (a) density

Intermolecular Forces Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms‚ molecules or ions). They are weak compared to the intramolecular forces‚ the forces which keep a molecule together. There are a few types of attractive intermolecular forces such as: Dipole-Dipole Forces Dipole–dipole interactions are electrostatic interactions of permanent dipoles in molecules. These interactions tend to align the molecules to increase the attraction

The Five Forces Framework and Competitive Strategy In this framework due to Michael Porter there are two high-level stages in the creation of competitive strategy‚ each stage corresponding to a high-level determinant of profitability mentioned in the previous section. The first stage is the assessment of the attractiveness of the industry in which a given company is embedded based on a structural analysis of the industry. In this stage‚ called the five forces framework‚ five forces that influence

What is the effect of coffee on plant growth compared to water? This is the question I was stuck to figure out. So‚ why would an average person care about the effects of coffee on plant growth? Well‚ the average growth time for a lima bean‚ when given water‚ ranges from 60 to 150 days. Information about plant growth is from various different websites.

HYDROSTATIC FORCE (EXPERIMENT 1) INTRODUCTION The determination of force which are exerted by liquid which are at rest on surface immersed in liquids. From the study by hydrostatic‚ the following principles have been established : a) There are no shear stress present when the fluid is not in motion. b) The pressure exerted by a fluid under hydrostatic conditions. This pressure acts perpendicular to an immersed surface. c) Hydrostatic pressure various linearly‚ increasing with an
