Erica Salas Triplet USU-1360 March 20‚2012 Reliance on Fossil Fuels and consequences Our “energy crisis” has been the big talk of politics ever since the early 1970’s. In 2007‚ the United States of America Energy Information Administration researched that eighty seven percent of global energy consumption comes from fossil fuels. The worlds most reliable industries provide fuel and electricity to modern societies and have made millions. People have high consumption lifestyle revolving around

In soccer‚ the length of the ball in air when it is kicked is the hang time. Air resistance or adding a curve to the ball will increase its hang time. Hang time can be calculated by H= 1/2 g(gravitational acceleration)times t(time) times 1/2. As the player kicks the ball with the inside of his foot he creates a curve on the ball and increases hang time due to air resistance acting on it. Kicking the ball straight will have a low hang time and just keep it low to the ground. The higher the ball is

PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

Debate Opening Statement Can we change our impact on the rate of global warming? There are all these campaigns for us to combat global warming and reduce our emissions‚ we have all the science to maybe not stop it but effectively reduce it to stable conditions. It is evident that the temperatures and sea levels are rising and this proves global warming is out there; but it still doesn’t make a difference we still do nothing because Global warming is irreversible; we are so deep
