State Principles and Policies government by representation Government by representation is the essence of a republican government. As sovereignty resides in the people‚ it is the people that establishes the government that governs them. Hence‚ sovereignty is exercised in two ways: directly and indirectly. Indirectly‚ sovereignty is exercised through the elected representatives or commonly called public officials. These officials are accountable to the people. Their acts are considered acts of

Fame‚ wealth‚ freedom‚ and success. Every person desires a life where riches‚ glory‚ or freedom surround them. Numerous people consider this dream the American dream‚ however‚ is it truly possible to achieve? Even those various immigrants who travel a great distance to come to America to live their own American dream shortly become intemperate people. The idea of the American dream is not attainable because people in general are exceedingly paradoxical and are constantly left yearning for more in

particles are given the sizes of equivalent spherical particles. The density of a soil-water suspension depends upon the concentration and specific gravity of the soil particles. If the suspension is allowed to stand‚ the particles will gradually settle out of the suspen- sion‚ and the density will be decreased. The hydrometer is the instrument used to measure the density of the suspension at a known depth below the surface. The density measurement‚ together with knowledge of specific gravity

Discussion a) The value of bulk density is 1.7921 × 10-3 kg/mm3 and the moisture content value is 0.31 %. b) Based on our visual observation‚ the colour of the soil sample that we had was light brownish. The texture of the soil was not too dry and either wet‚ it is loose because it contains broken rock particles or they are the resistant components of rocks broken down which it has rotund shape. Conclusion 1) The possible sources of error which made during experiment was first of all

Activity 3: DIY Lava Lamps Students will understand density‚ chemical reactions and simple circuits by creating a nifty take home‚ reusable lava lamp. Set-up: Every student will need two LED lights‚ two coin batteries‚ and a water bottle. Keep the water‚ vegetable oil and food coloring at a communal table so that you can track the amount each student is using. Electrical tape can be distributed to the tables to share.

Unit Weight is influence by gravity forces while mass isn’t (Unit Weight=Weight/ Volume while Density= Mass/Volume)- Weight = Mass x Gravity acceleration So we can use the similar equations on related calculation if there is only density Specific Gravity Specific gravity can be determined as a ratio of the unit weight of the soil material to the
