Egg Flotation college application essay help Art Design assignment help

March 4, 2010 Egg Buoyancy and Density: Can you make an egg float by changing the density of water? If you put an egg in tap water, it will sink to the bottom. If you add enough salt, the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge. Anyone can do it.

You need to gather all your aterials before you begin. You’ll need three glasses or beakers. You can use bottled or tap water. It’s better if it isn’t cold water. Warm water dissolves faster. A tablespoon, salt and three eggs will complete the materials. Be very careful not to break the eggs. It makes a really big mess! Now you can start the experiment. Fill three glasses with two cups of water each. Dissolve one tablespoon of salt in the first glass and two tablespoons in the second glass. Don’t put any salt in the third one.

Label each glass. Watch the eggs for the next twenty four hours. When the time is up, take notes on how far the eggs have risen. Draw your own conclusion. This is a really cool science project. I got most of my information from sciencehound. com. I learned a lot about density and buoyancy. You can increase the density of water by adding salt. Eggs float at different levels in water depending on how much salt is added. If no salt is added, the egg Just sinks to the bottom. It’s almost like doing a magic trick!

Legal Theory

Legal Theory.

Description Legal theory helps us to gain a deeper understanding of law and its everyday operation. Critically assess the extent to which legal theory assists you to see the following: That “Law cannot be built on law” (L. Fuller, ‘Positivism and Fidelity to Law—a reply to professor Hart’ (1958) 71 Harvard Law Review 630, at p. 645). Discuss with reference to both Hart and Dworkin. Context of the essay: In short the essay will be about positivist and interpretive law theories. Professor Hart is a positivist law theorist, and Dworkin is an interpretive/natural law theorist. Dworkin first rejected Hart’s arguments in his book ‘Law’s empire’ to which professor Hart replied to in the postscript of his book ‘Concept of law’. Fuller (mentioned in the essay question) is a natural law theorist and also disagrees with Hart. The quotation that “law cannot be built on law” is a generic rebuke of positivist accounts of law that hold that law is simply what is institutionally recognised as law, such as Hart’s concept of law as the union of primary and secondary rules. The quotation is designed to give the choice as to how to respond to it, whether agreeing with the quotation and the natural law theory with use of sources (Dworkin, Fuller etc), OR agreeing with Hart’s Positivist law theory, OR finding both interpretive/natural and positivist theories persuasive.
