GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

The movie Equilibrium directed by Kurt Wimmer‚ and the book 1984 written by George Orwell both explore what would happen when a government has complete control. When you let someone think for you and make all of your decisions‚ you lose what makes you human‚ which is your free will‚ and your ability to make conscious decisions. In both the text and movie they take away human identity to gain control. The key differences are the ways Big Brother and Father seize control‚ and what effect it has on

Case in the news: Demand/Supply and Equilibrium This article is based on the fundamental idea of supply and demand of the iPhone 5 whose demand has outstripped its supply. Due to the fact that the demand is so high‚ even those who pre-ordered the new slim iPhone 5 had to wait until October to get this new phone. The sales have broken all previous records and stand tall at 2 million phones in the first 24 hours. According to the article people had been

main objective of this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the

PROBLEM SET 3 Problems for Chapter 3 1. Suppose the consumption function in the U.S. is represented by the following equation: C = 200 + .5 YD‚ where YD = Y – T and T = 200. a. What is the level of consumption in this economy if YD = 0? Briefly explain how individuals “pay for” this consumption when YD = 0. b. Given the above parameters‚ calculate the level of consumption if Y = 1200. Suppose Y increases to 1300. What happens to the level of YD as Y increases to 1300 (i.e. calculate

offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents‚ and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically‚ a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population‚ isolation from other populations‚ no net mutations

The Jewish Scripture starts right at the beginning of time itself‚ where God created the universe‚ and only then did he create the earth (Genesis 1). Right from the beginning God has had an intimate connection between God and the world‚ and this connection is believed to continue throughout time. From the moment god created humanity (Gen. 1:26)‚ we were created for the one purpose to protect the earth. But it is in the story of Noah that we perhaps truly learn about the role that God had created

temperature before and after mixing was recorded and included in tables. When the experiments were completed analysis was performed using the laws of thermodynamics. The data collected was used in equations to find theoretical values for final equilibrium temperature. The theoretical values were compared with those measured during the experiment. The total average percent difference between the measured final temperature and the theoretical final temperature is less than 5.0%. This low deflection
