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

from various kind of informative books i borrowed are: A wind turbine is a product that converts wind energy into electrical energy that is use to distribute to the homes of people. Benefits of a wind turbine: It does not release any harmful gases into the air when powered and it is also affordable in many different countries for supplying electricity to homes‚ by converting the wind energy to electricity for distribution. A hydropower is a production of electrical power through the use of

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

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.
