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

attainment Alison L. Booth & Hiau Joo Kee Received: 13 January 2006 / Accepted: 9 November 2007 / Published online: 11 April 2008 # Springer-Verlag 2007 Abstract Using the British Household Panel Survey‚ we investigate if family size and birth order affect children’s subsequent educational attainment. Theory suggests a tradeoff between child quantity and “quality” and that siblings are unlikely to receive equal shares of parental resources devoted to children’s education. We construct a new birth order

out of a textbook now all you see is students working on their laptop and other devices to help accomplish their work. More and more schools are implementing these certain devices to help their students become more hands on at an early age. Not only does technology help students accomplish their work but they also receive quick feedback from their teachers on assignments. Once students gain quick criticism on their assignments they

Lab Report The effect of temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase

In the article “Does Texting Affect Writing?”‚ author Michaela Cullington tells of her research to explore the topic of texting and writing and discover whether texting effects students’ writing or not. Michaela begins her argument by stating some of the positive and negative claims relating to texting and writing. She also tells the reader about things that have evolved and come to exist from texting‚ and how it relates back to how students are now writing. The author not only did research on this

atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes

process can be affected by several variables; one of the most notable variables is the temperature of the plant’s environment. Previous study has led me to conclude that when the temperature of the plants’ environment is low‚ the rate of photosynthesis is also low because the enzymes responsible for photosynthesis are not able to absorb as much heat energy and in turn will move slower. In contrast‚ if the temperature of the plant’s environment increases‚ the rate of photosynthesis will also increase
