the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific heat capacity) x temperature change = energy transferred

Increase the momentum of the object over a long time 8. Most street barriers are made of hard rubber or plastic materials that easily give in or dent when hit. Why is this so? A. To reduce the vehicle’s kinetic energy when it collides with the barriers B. To store potential energy in the bumpers of vehicles C. To reduce the impact force when hit by a vehicle D. To reduce the impact time when the barriers hit the vehicle 9. What is the momentum of a 20 kilogram cart moving

Solar Energy Outline: Abstract Recently‚ the solar energy technology market has experienced phenomenal growth. Due to growing public awareness of environmental issues‚ clean energy research funding has increased. This funding increase has created dramatic technological improvements. Compared with traditional energy‚ solar energy is showing many remarkable advantages. Despite its technical and economic limitations in the present‚ it is expected that solar energy will play an important role in

Group Project Homework: Ch 1 page 28 10) Although forces in the foreign environment are the same as those in the domestic environment‚ they operate differently. Why is this so? The concept of forces in business should affect the foreign and domestic environment the same‚ but in actuality the forces in the two environments act differently. First the values of differing countries can create rifts in businesses around the world. Many incidents occur where a country will place an embargo on another

Alternative Energy Sources Fossil fuels will not last forever. If the human race wishes to continue to live the way we do‚ then we have to look at alternative energy sources such as: geothermal‚ nuclear‚ solar‚ wind‚ and hydroelectric energy. Alternative energy sources are not without faults‚ but along with faults‚ there are benefits and solutions to the issues. Geothermal energy is a well-proven energy resource that can be used to provide both heat and electricity. Geothermal energy is very predictable

Renewable energy‚ a source of energy that holds a significant promise to help reduce the amount of toxins that are by-product of too much energy use and bring a positive impact on our planet that we currently use as our source of energy.These include energy from water(Hydropower)‚ wind‚ the sun(solar power)‚ geothermal sources‚ and biomass fuel. In contrast‚ fuels such as coal‚ oil‚ and natural gas are non-renewable‚it’s finite and will some day run out completely. One of the most common renewable

However‚ waiting until supplies are exhausted would place a major hardship upon future energy demands. Even the existence of other conventional sources such as hydropower‚ wind energy and biomass will not suffice keeping in mind the rapid advancement. It is therefore imperative to look for alternative sources of energy in order to
