drawn through leads‚ and presses it onto the carbon disc below. This leaves a dot on the tape for every hit. The power source ensures that the vibration of the stylus will be regular. The period(T) of the timer it takes for the stylus to move all the way down and then up-one complete cycle. The frequency(f) of the timer is how many times the stylus goes through a cycle in a second. So the frequency is the reciprocal of the period‚ and the period is the reciprocal of the frequency. We will calculate

global race comes into play‚ we show up empty handed. Example KYOTO and Copenhagen failed to make agreements now they have been postponed‚ countries like US not signing‚ as well as Russia and Japan recently pulling out. There are several reasons why the world is doomed but there are two important ones‚ we are a growing world‚ our population increases exponentially‚ how do we possibly think we can slow down CO2 when our population increases by a billion on average every 12 years. Now the reality

Daily Use of Physics Jason L. McDuffy University of Memphis Physics 1 (online) Project 1 Daily Use of Physics Physics is considered to be a powerful lens that helps people view the everyday world. Physics is reflected in the everyday phenomena‚ puzzles and toys that offer a variety of interesting challenges leading to deep and interesting problems that derive from science and mathematics. It provides us an understanding of energy‚ motion and explains these facts as

charge. We can describe the flow of electric charge in several ways. These include the quantities Current‚ Voltage and Power. Current * Current (I) is the rate of flow of Charge Carriers‚ such as electrons. Current is usually thought of as moving in the direction of positive charge‚ so from the positive power supply to the negative. However‚ since in metals it is electrons that carry electric charge‚ the actually flow is opposite to the way in which we think of it. * Current it the amount of Charge

Next would be how you hold the guitar while sitting or standing. This is a very simple technique and very hard to do incorrectly. The back of the guitar will be flush against your midsection. If the guitar covers most of your torso‚ then it may be too big. If it is too big‚ it will be difficult to play smoothly. Now that you know how to hold the guitar‚ and where to put your hands‚ you should know how to put the strap on the guitar‚ simply referred to as “strapping the guitar”. Both ends of the strap

BOOM’ S PROBLEM PS 4.3 – Torque (Rotational Equilibrium) Problems 1. A crane supports a 3.0 kN weight as shown. The crane’s boom is 8.0 m long and is at an angle of 30˚ from the horizontal. If the hydraulic support is attached to the boom 2.0 m from the bottom of the boom‚ then: a) what is the compressional force in the hydraulic? b) what is the magnitude and direction of the force on the pin at the bottom of the boom? a) ∑Torque = 0 F cos 30˚ x 2.0 = 3000 cos 30˚ x 8.0 F = 24

http://www.physicsclassroom.com/mmedia/circmot/rcd.cfm What is ‘g force’ in physics? G‚ in physics‚ a symbol relating to gravity. A capital G indicates the gravitational constant‚ as explained in the article GRAVITATION. A lower-case g stands for the acceleration imparted by gravity at the earth’s surface. An acceleration of 1 g is 32. 1 feet per second per second (9.8 m/s2). Fliers and astronauts may experience accelerations many times larger than 1 g. These accelerations are usually expressed

LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity
