Before the 1930’s or the first set of "talking picture films‚" all films were completely silent. Usually‚ they had some form of text card that would flash upon the screen explaining what had happened in the previous scene. To keep the film from just being a projected book‚ the film would be accompanied with anything from full orchestras to a pianist. A correctly timed note or a special tone would almost give a sense of depth to a two-dimensional image. Not only this‚ but the music had a second purpose

TAP 601-1: Brownian motion Brownian motion (named after the botanist Robert Brown) is the presumably random drifting of particles suspended in a fluid (a liquid or a gas) or the mathematical model used to describe such random movements‚ which is often called a particle theory. The experiment of Brownian motion in a smoke cell is a classic experiment that gives strong circumstantial evidence for the particulate nature of air. Materials: ✓ Smoke cell‚ incorporating a light source

Introduction The purpose of this section is to introduce the concepts of displacement‚ velocity‚ and acceleration. For the sake of simplicity‚ we shall restrict our attention to 1-dimensional motion. Displacement Consider a body moving in 1 dimension: e.g.‚ a train traveling down a straight railroad track‚ or a truck driving down an interstate in Kansas. Suppose that we have a team of observers who continually report the location of this body to us as time progresses. To be more exact‚ our observers

P hysics 2 06 Example P roblems Newton’ s Laws of Motion Problem 1 . A) What is the direction of the acceleration of an object that is slowing down while heading northward? Answer : The acceleration would be southward since the net force required to cause this acceleration would be southward. The change in velocity is directed southward. B) What is the acceleration of an object thrown straight up in the air‚ near the surface of the earth‚ at the very top of its flight? Answer : The acceleration is

The reaction to the choice to make Thorsten Heins the new CEO was seen as too little too late. People don’t feel that Heins will be able to shake up the company enough to make a big enough change. They are hoping the new phone coming out from Blackberry called BB 10 will do
