mass of the green one. Before colliding, the pucks approach each other with momenta of equal magnitude and opposite directions, and the green puck has an initial speed of 10.0 m/s. Find the speeds of the pucks after the collision if half the kinetic energy is lost during the collision. speed of Blue puck: 5.89 m/s Speed of Green puck: 7.069 m/s 2)The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance d apart on

utilizing the kinetic energy of steam flow, the turbine could achieve a higher efficiency. As a result, the steam turbine has supplanted the reciprocating engine as a prime mover in large electricity-generating plants and is also used as a means of jet propulsion. The action of the steam turbine is based on the thermodynamic principle that when a vapor is allowed to expand, its temperature drops. In turn, its internal energy is decreased. This reduction in internal energy is transformed into

generators used in EDM Analyse working principle of RC type EDM generator 1. Introduction Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining process, where electrical energy is used to generate electrical spark and material removal mainly occurs due to thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high strength temperature resistant alloys. EDM can be used to machine difficult geometries in small batches or even on

Environmental factors Social Forces: Waste management is not just for the welfare of one state/society or for specific public but it would work for everyone, this will include different demographics of population. No matter people are young/old, male/female, and rich/poor they all will be benefitted by the work of waste management. Waste management has main purpose of making everything green so it would work for all the religions and make their surroundings clear, this company will obviously

3-DAY Exercise Analysis Derrick Murphy SCI/241 Clayton Wilson November 2, 2012 3-Day Exercise Analysis What are your current exercise habits? I would have to stay my current exercise habits is going to the game at least four to five times and week for at least an hour in a half. My primary is weight lifting and strength training all most every day because they help me keep my body in great shape. Keeping in shape is need at my job because that is a very physical place to work and every part of your

Essential Facts for Physical Science Scientific Investigation, Reasoning, and Logic 1. SI (metric) measures, recognized around the world, are a standard way to make measurements. 2. Bar graphs, line graphs, and circle graphs are powerful tools for displaying and interpreting data. 3. To communicate the plan of an experiment accurately, the independent variable, dependent variable, and constants must be explicitly defined. 4. The number of repeated trials needs to be

Career Plan Building Activity: Competencies and Career Interests Profiler My Results I had five bars in innovating, which, four bars for strategizing, adapting to change, and cooperating. I had three bars each in researching and coping with pressure. There was no surprise for most of the results except for the researching one, I love to do research and ask questions. The five bars for innovating I think come from the fact that I hate doing things the way they “have always been done”

Plants and Semiconductors A Contrast and Comparison of Energy Conversion J’Haun Egerson Strayer University Photosynthesis is the process used by plants to harness the suns energy. The plants use this harnessed energy to produce food. The leaves of plants help trap the energy from sunlight. The process of photosynthesis transforms the solar energy into the chemical energy of a carbohydrate. Photosynthesis occurs mainly in plant leaves, little to none occurs in the stems, roots, etc. To dive
