The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

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

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

Vinny Candelora Physics current event 3/3/13 This has never been done before at high energies and represents a significant breakthrough‚ Cline said‚ adding that it also may have implications for fusion as a new energy source. In free space‚ a plane-wave laser is unable to accelerate an electron‚ according to the Lawson-Woodward theorem‚ posited in 1979. However‚ Yu-kun Ho‚ a professor at China’s Fudan University in Shanghai‚ and his research group have proposed a concept of what physicists refer

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. Also‚ every

AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2. (17P15)

Response: How to Get a Real Education Scott Adams shares with us the ideal framework for an entrepreneurial curriculum. In his article How to Get a Real Education‚ he reinforces the fact that the whole is far greater than the sum of these parts‚ especially in the context of an entrepreneur. Adams tells us of a couple stories from when he was in college and how he used the skills of an entrepreneur to become successful. He saw opportunities‚ sometimes embedded within problems‚ and worked them to

Productivity After two quarters of increasing levels of production‚ the CEO of Canadian Fabrication & Design was upset to learn that‚ during this time of expansion‚ productivity of the newly hired sheet metal workers declined with each new worker hired. Believing that the new workers were either lazy or inefficiently supervised (or possibly both)‚ the CEO instructed the shop foreman to "crack down" on the new workers to bring their productivity levels up. ◦ Explain carefully in terms of production
