2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm‚ the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

In the dim twilight of dawn‚ before sunrise and in his half-conscious state‚ having just awoken from a deep sleep‚ Murdock imagines that he sees a great hairy bear trying to enter the cabin through the open window. With the rifle in his hand‚ quaking with fear‚ his one thought being to protect his wife’s body‚ he aims and delivers a single thunderous shot. The shot ricochets off the window frame and is followed by a sound of expending air. Rushing over to the table‚ Murlock finds it bare and his

work breakdown structure A WORK BREAKDOWN STRUCTURE (WBS) IS A DECOMPOSITION OF ALL THE WORK NECESSARY TO COMPLETE A PROJECT. A WBS IS ARRANGED IN A HIERARCHY AND CONSTRUCTED TO ALLOW FOR CLEAR AND LOGICAL GROUPINGS‚ EITHER BY ACTIVITIES OR DELIVERABLES. THE WBS SHOULD REPRESENT THE WORK IDENTIFIED IN THE APPROVED PROJECT SCOPE STATEMENT AND SERVES AS AN EARLY FOUNDATION FOR EFFECTIVE SCHEDULE DEVELOPMENT AND COST ESTIMATING.

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

The family members themselves perform one of the factors that shared in the breakdown of their family by making self-interest before the need of the family. When this happens‚ family members alienated from each other and communication breaks down. The structure of the family is vanishing because everyone follows his desire and tries to achieve his aim on the cost of family scattering. Al is the member whose chief interests seem to be girls and cars. He feels that he stays with his family against
