Water‚ Life Cannot Exist Without It Water is the world’s most natural resource and without it there would be no life on earth. Nature limits our available supply of water. Virtually all of human uses require fresh water. 97% of the Earth’s water is salt water and only 2.5% is fresh water of which over two thirds is frozen in glaciers and polar ice caps. The unfrozen freshwater is mainly ground water with only a fraction on the surface. Fresh water is a renewable resource but the world usage

Destiny Stuart Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and

Purpose/Problem/Question Which type of friction is the largest force – static‚ sliding‚ or rolling? Which is the smallest? II. Background Information From our previous activities that we did in class‚ I know that static friction is a very large force. The force is larger than rolling‚ sliding‚ and fluid friction. I also learned that rolling friction is the smallest type of force. This information may connect to my final analysis. III. Hypothesis If static friction is the largest force‚ then either

Coefficient of Kinetic Friction Objective: After completing this experiment‚ you should be able to measure the coefficient of sliding friction of an object that is located on an inclined plane. Apparatus: Inclined Plane Pulley attachment for plane Wooden blcok‚ with hook attached Meterstick Felt Set of masses String Protractor Procedure: 1. Place the board in the position shown in Figure 7-1. 2. The angle of the board should be small enough so that the wooden block will not slide

Exporting _______________ gave this class a chance to help them figure out which floor matting will help a cargo box stop from moving. One factor that is used is friction. Friction happens when two surfaces rub against each other and may cause heat. Also there are four types of friction which are static‚ sliding‚ rolling‚ and fluid friction. The company needs the class to find out what type of flooring is best to use to stop a cargo box from moving. They have game systems that are imported and exported

succeed in life without education A lot of people think that in today’s society‚ having a degree is not very important for getting a better job and making money. Actually‚ they think they only need a chance which will make them succeed. Not only Bill Gates‚ but also Steve Paul Jobs stopped schooling and began to run their own company. As a result‚ both of them succeeded. Although some people seem not interested in going to school and they believe they can succeed even without any education

How will our life go on without internet? It’s hard to imagine that we live in a world without internet which plays an important role in many aspects of our lives. Thus‚ it’s worth discussing how our life will go on without internet to see what benefits and disadvantages it brings to us. It’s beyond question that our life will be inconvenient if we’re not available to internet. For one thing‚ we students surf the internet for information frequently in order to write papers‚ find materials for self-study

5. Quality of Life with and without a cochlear implant Many hearing people believe that the deaf experience unnecessary difficulties in life that can be otherwise avoided with the use of a cochlear implant. The deaf are unable to hear the simple sounds in life that we take for granted or cannot speak for easy communication. It is argued that a deaf child will experience severe isolation and must rely on others for various tasks they must complete‚ which has potential to deplete their independence

People Can’t Succeed In Life without Education In recent years‚ the ratio of quitting education in high-schools and universities improves. A lot of students think they can get some jobs without education. They want to do anything that can give them more knowledge than in school. Besides‚ many wealthy people over the world have never graduated from any universities‚ even though they stopped studying in high-school. Young people see it as examples for their life. A number of people think education
