Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

Man on Wire Man on Wire is a very interesting nonfiction documentary film of one man’s story. Through reenactment footage and original footage the director of this film‚ James Marsh uses many strong aesthetics that helps to get Philippe Petit’s story across. As well give the audience the truth and reality of the world. Even if it was illegal and daring‚ Philippe Petit was determined to tightrope walk between the New York City’s World Trade Center’s Twin Towers. Jf hgjk fh irgk jfh uhg uhu juf mfn

placed 1.8 cm apart. When released‚ they begin to accelerate at 245 m/s2. What is the magnitude of the charge on each sphere? 2. For what electric field strength would the current in a 2.0 mm diameter nichrome wire be the same as the current in a 1.0 mm diameter aluminum wire in which the electric field strength is 0.0095 N/C? [Conductivity of Aluminum = 3.5 x 107Ω -1m-1 and conductivity of Nichrome = 6.7 x 105Ω -1m-1] 3. What is the escape speed of an electron launched from the

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change

PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit

.Physics is the field of scince that controls the Earth‚ the Moon‚ the Sun and the Universe It is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration
