ZHEJIANG UNIVERSITY Department of Physics Thermal Physics Problem Set #3‚ Solution Date: 2013/03/29 1. If we apply the highly successful kinetic theory of gases to a metal‚ consider as a gas of electrons (in fact‚ back in 1900 Drude constructed the theory‚ hence the Drude theory of metals)‚ and assume that the electron velocity distribution is given by the Maxwell-Boltzmann distribution‚ what would the most probable speed‚ average speed‚ and rms speed for electrons at room temperature

Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Physics in My Daily Life “Write an essay of 1500 words‚ double spaced‚ in standard fonts ‚ giving credible references on the use of physics in your daily activity. You need to mention 5 or more activities where physics is used. Please follow the APA format.” As a senior in college‚ I lead a rather busy life. My days usually follow the same routine and pattern. I wake up at 7am everyday‚ so I am rather tired. To get going in the morning‚ I usually drink a cup of coffee. Then I attend my classes

In Newtonian physics‚ free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity‚ where gravitation is reduced to a space-time curvature‚ a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards

5 of the biggest unsolved mysteries in physics The mysteries of the universe are as vast and wide as existence itself. Throughout history‚ mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker’s Guide to the Galaxy‚ "I think the problem‚ to be quite honest with you‚ is that you’ve never actually known what the question is." True‚ we have yet to come up with the answers to life‚ the universe

What Makes A Ride Thrilling? Year 11 Physics ERT Introduction Theme parks have always been a source of thrills and amusement‚ as well as major source of tourist revenue. As celebrated coaster designer John Allen states: “You don’t need a degree in engineering to design roller coasters‚ you need a degree in psychology” (Focus‚ 2009) For decades‚ thrill rides have implemented psychological thrills such as long upward climbs building anticipation‚ surprise twists and turns‚ and hills that
