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

2a Homework 08 - Solutions You need a 45 Ω resistor‚ but the stockroom has only 20 Ω and 50 Ω resistors. How can the desired resistance be achieved under these circumstances?" " A. Put one 50 Ω and one 20 Ω resistor in parallel and then put that combination in series with a 20 Ω resistor." B. Put two 50 Ω resistors in series and then put that combination in parallel with a 20 Ω resistor." C. Put one 50 Ω and one 20 Ω resistor in series and then put that combination in parallel with

play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction.
