Tutorial – Work‚ Energy (Assume the acceleration due to gravity‚ g = 9.81 m/s2 ) 1. Calculate the work done when a force of 40 N pushes an object a distance of 500 m in the same direction as the force. 2. Calculate the work done when a mass is lifted vertically by a crane to a height of 5 m‚ the force required to lift the mass being 98 N. 3. A spring‚ initially in a relaxed state‚ is extended by 100 mm. Determine the work done by using a work diagram if the spring requires

Describe and explain the factors that influence how much a work a river can do (25) The work that a river does is erosion‚ transportation and deposition. The amount of work a river can do is dependent on the energy it has and this energy is determined by many factors. The study of water flow in a river channel is known as hydraulics. Hydraulic geometry is the study of the relationships that exist within river channels that ultimately determine how much work the river will be able to carry

Why is an understanding of evolutionary and population processes important for species conservation? Abstract Evolution is it a theory of previous life becoming more like present life over time through means such as "natural selection" With an endless diversity of life‚ and variation as a result of the interactions of organisms with their environments. Fundamental to the process of understanding how evolution works is to look at a combination of many mechanisms such as genetic variation‚

Introduction Several years ago energy drinks barley existed. Not all people were familiar of it. People who consumed it did not understand the bad health effects behind it. This is because they were not as popular as it is today. Nowadays‚ energy beverages markets grew rapidly in recent years. There are many different brands of this drink in the world today. These beverages have caused many health problems to those who consume them. One group affected by the high consumption of energy drinks are children.
