3.4.1 Study: Buoyant Force and Archimedes’ Principle Physical Science (S2541215) Study SheetStudy Sheet Claire Hasenoehrl Date: ____________ Use the spaces below to take notes on the key concepts presented in this study. Main idea: Buoyancy of an object is determined by properties of the object as well as properties of the fluid surrounding it. density=mass/volume More dense at bottom The result of pressure exerted equally in all horizontal directions by water. Pressure at bottom greater than

Why is flooding prone to Bangladesh? Bangladesh suffers from regular and extreme flooding for the following reasons‚ first being that its one meter above sea level‚ as well as it being a LEDC meaning it’s a less economical developed country. The rivers leading from the Himalayas flow into the sea‚ when they suffer with heavy rain the excess water starts to over flow and flood and waterlog land and surroundings. The physical causes are‚ the monsoon climate brings very heavy rain and snow‚ and soils

On Friday February 03‚ 2012‚ we visited Don Egerico Mora Camacho and his wife Cecilia’s ranch. “They own 95 hectares of land‚ of which 5 hectares‚ in the lower part of the property‚ is in organic coffee and 90 hectares‚ which extend from their house up towards the Caraigres Mountains‚ is in cattle pastures.” We examined the land use capacity and made an evaluation the class of the soil. Honestly‚ this was a very interesting project for me because I had never done an experiment like such. Having

The trees around us are extremely important and have always been necessary for improving the human condition - both during its life and after harvest. It is not a stretch to believe that without trees we humans would not exist on this beautiful planet. In fact‚ some claim can be made that our mother’s and father’s ancestors climbed trees - another debate for another site. So‚ trees are essential to life as we know it and are the ground troops making up an environmental frontline. Our existing forests

Coal Industry of pakistan SWOT ANALYSIS STRENGTHS Pakistan has a very large coal reserve base only Thar coal can be used to make 40‚000 MW of Electricity for the next 100 years. Regional powers like China are very much interested in the project and are willing to pour billions of dollars in these projects if the Govt. of Pakistan issues sovereign guarantee. Sector will essentially contribute to the wiping out of the difference in the electricity shortage. It would stabilise the economy

In the article “Houston Flood Waters Are Tainted With Bacteria And Toxins‚ Tests Show” by Sheila Kaplan and Jack Healy‚ flood waters in Houston neighborhoods have been contaminated. Plus‚ the spread of the toxic waters is not clear on how far they have gone‚ but it is hinted that the breaches of several waste plants have made the waters more dangerous. Testing has occurred and has found traces of Escherichia coli which is a fecal contamination. In the Clayton Homes public housing development‚ high
