Title Impact of water jet Objective The purpose of this experiment is to demonstrate the application of the momentum equation. The force generated by a jet of water deflected by an impact surface is measured and compared to the momentum change of the jet. To relate: • Direct measurement of impact forces • Effect of flow rate and velocity • Effect of various deflection angles Introduction / Theory Newton’s Second law states that The applied forces is equal

Water for Elephants. by Sara Gruen. "Life is the most Spectacular Show on Earth!"- Sara Gruen‚ Water for Elephants. "All I can do is put in time waiting for the inevitable. Observing the ghosts from my past‚ rattling around in my vacuous present. They crash and bang and make themselves at home‚ mostly because there’s no competition. I’ve stopped fighting them." says Jacob Jankowski‚ who is now ninety (or ninety three). Mr. Jankowski reflects upon memories of himself as a young man‚ tossed by

Required Question for all Students I chose the book Water for Elephants by Sara Gruen. I chose this book because I had watched the movie a long time ago and everyone says the book is always better than the movie. I knew I was going to like it because I love animals and I have always wanted to be a veterinarian just like Jacob in this book. I thought it was very inspiring how even after Jacob learns that his parents have been killed in the car crash and their home has been mortgaged to pay for his

flows‚ and the water falls into the pond is where I did my observation. I took the time to sit on my property‚ at my grandparents house‚ which is located in the country side. I sat on a wooden bench over looking running water for 30 minutes observing the wilderness‚ and the surrounding sounds. The water was flowing fast down stream‚ with an abundance of rocks in the water. The water was completely clear‚ and made a rushing sound as it moved. I could see small fish swimming in the water. There was a

battery my salt water battery has the three main components‚ the electrolyte (in case you didn’t know its like a liquid that conducts th electric current (I hope I spelt that right))‚ a cathode (the negative electrode) and the an anode (the positive electrode). As you may or may not know a chemical reaction must occur so that that chemical energy can be converted into electrical energy which is then used for whatever. In my salt water battery the electric current passes through the salt water which separates

Physicists Daniel Collodon and Jacques Babinet reported in the 1840s that light could be directed along jets of water for fountain displays. In 1854‚ John Tyndall‚ a British physicist‚ demonstrated that light could travel through water jets‚ thereby
