The sun by definition is the star that is "the central body of the solar system‚ around which the planets revolve and from which they receive light and heat." This self-luminous star is not only the largest object in the solar system containing 99.8 percent of the total mass but is also a fundamental necessity to every human and living thing’s life. The position of the in relationship to the sun‚ Earth determines the time of the year or season. The problem states "assume that at this time of

properties corresponding to the idea of absolute rest. They suggest rather that‚ as has already been shown to the first order of small quantities‚ the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good.1 We will raise this conjecture (the purport of which will hereafter be called the “Principle of Relativity”) to the status of a postulate‚ and also introduce another postulate‚ which is only apparently irreconcilable with

r r ∂D Jd = ∂t MAXWELL’S EQUATIONS These four fundamental equations of electromagnetics on the basis of three separate experimentally established facts‚ namely‚ Coulomb’s law‚ Ampere’s law (or the Biot-Savart law)‚ Faraday’s law‚ and the principle of conservation of electric charge. The validity of Maxwell’s equations is based on their consistency with all of our experimental knowledge to date concerning electromagnetic phenomena. The physical meaning of the equations is better perceived in the

clock reaction. The goal of this aim is to find out what catalyst is best to make this reaction occur at the fastest rate. 3. Determine the effects of the presence of ethanol on the rate equation. It is known that ethanol effects hydrogen peroxide and therefore it has an effect on the rate equation. This aim will find out the effect of ethanol by carrying out the iodine clock reaction with and without ethanol present and the results will be compared to draw a conclusion. A2 AIMS:
