SYSTEM OF PARTICLES AND ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation

California High Speed Rail Authority website in 2010 alone green house gas emissions in the U.S. totaled 6‚821.8 million metric tons of carbon dioxide (CO2). Central Valley residents in particular have seen increase in aspiratory ailments. The State Legislature passed Global Worming Solutions Act in 2006‚ which is aimed to reduce statewide emissions by 2020 to 1990 level (17 %). High-Speed Rail One of the key parts of the strategy is the reduction of cars on roads by replacing it with high speed railway

How did the Hindenburg catch fire and explode? On May 6‚ 1937 a German airship (LZ 129 Hindenburg) was landing in Township‚ New Jersey when an electrostatic discharge ignited leaking hydrogen and causing the Hindenburg to catch fire. A electrostatic discharge is a sudden flow of electricity between two charged objects caused by contact. There was a total of 36 casualties which were 13 passengers‚ 22 crewmen‚ and even a worker on the ground. 62 out of the 97 passengers survived the crash. (wikipedia

The effect of temperature on the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane

Maintaing the speed limit as it is will be more effective than to lower the speed limit for various reasons. Reasons such as it will make less traffic‚ keep drivers focused‚ and allow people to get to their destinations faster. Also making the speed limit higher will force cars that drive on highways and interstates to be more reliable and better maintenance. This will lower break downs onn high ways and interstates because people will think twice before they drive their irreliable vehicle on the

INTRODUCTION INTRODUCTION TO INTELLECT SPEED BREAKER USING CAN PROTOCOL This project deals with limiting the speed of the vehicle by employing technology of embedded systems using “Peripheral Interface Controller (PIC 16F877A)”‚ when the vehicle enters the speed limiting zone. The parameter to be controlled in this project is speed. PIC has the advantage of enhanced FLASH memory with the modified Harvard architecture and having simple 35 instructions.
