major changes in social structures‚ people ’s attitudes‚ national institutions‚ acceleration of economic growth and reduction of inequality. According to Kindleberger‚ Economic development means an increase in output of goods and services in the economy. It is more important than economic growth because economic development is more comprehensive process than economic growth. Economic growth is a quantitative term as it represents quantitative increase in the production of goods‚ services and factors

Algae are simple organisms that typically produce their own food through photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very

EXERCISE 7 - Rotational Kinematics and circular motion 1. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°‚ 30 rad‚ and 30 rev‚ respectively? 2.1m‚ 1.2x102 m‚ 7.7. x102m 2.

constant. If a ball is attached to the end of string and swung at a constant speed (i.e. only the direction of the velocity is changing not the magnitude) then there must still be an acceleration. The acceleration is directed towards the center of the motion. This acceleration is call centripetal acceleration! 2.6.2 State the expression for centripetal acceleration. The acceleration of any object moving in a circle at a constant speed is given by the equation: (1) a⃗ =v2r It is important to note

entitlements. Needless to say‚ the number of people who travel to exotic holiday destinations across the world is on the rise. The tourism industry has witnessed tremendous growth over the last few years. And it looks like it will continue this upward trend. So what are the advantages and disadvantages of this trend? The growth in the tourism sector has many advantages. In many parts of the world tourism has created more jobs than any other industry. Tourism helps countries to earn valuable

Economic Growth Economic growth is the percentage increase in real national output in a given time period or the increase in the productive potential of the economy. Countries grwo at different rates‚ this is partly due to the fact that they are at different stages of their economic cycle. The economic growth for the UK is at 0.2%. The main measure of output is gross domestic product (GDP). GDP is the total value of goods and services produced in an economy during one year. Economic growth can be

Lauren Seymour- Growth and Decay Procedure: For the growth part of this lab‚ we started with 4 M&M’s in the cup. We shook the cup and poured the M&M’s onto a napkin. Then‚ we counted the number of M&M’s that had the “M” facing up. Next we added a new M&M for each one that was facing up and continued this process until all of our M&Ms were used (11 trials). For the decay section of this lab we began with a full cup of M&Ms. We shook the cup and poured all of the M&M’s
