create electrical energy‚ we must create thermal energy. Several techniques include using coal‚ natural gas‚ or nuclear thermal to create heat. Once heat is created‚ it is used to vaporize water and use the steam to propel a piston which turns an electric generator. Alternative energy sources include wind‚ solar‚ and micro hydro. 19.2 Nuclear Structure All matter is made up of atoms and in the centre of the atom‚ there is a nucleus. Within the nucleus‚ there are protons (+) and neutrons (neutral)

Quantities: Quantities that require both magnitudes and direction to specify them are called vector quantities or vectors. Displacement‚ velocity‚ force‚ momentum‚ weight etc. are the examples of vectors. Q5: A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds? Answer: As shown in figure‚ let us assume‚ the farmer starts from A. Given‚ length of each side = 10m Distance covered in 1 lap

particularly eco-conscious‚ but they have now made their way into the mainstream. Most major motoring brands offer Hybrids with models like the Toyota Prius‚ the Honda CR-Z and the Lexus CT proving popular. They work by combining a fuel engine with electric batteries‚ which reclaims energy when the car brakes or converts energy from the petrol in the fuel engine. However‚ more manufacturers are developing ’plug in’ Hybrids‚ which offer the option to recharge more powerful batteries through a common

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

PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

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

Fields in Psychology | Definition | Abnormal Psychology | It is the study of abnormal behavior. It is actually a branch of psychology that deals with the study of abnormal behavioral patterns and their causes. | Psychology of Addiction | A complete dependence on a certain substance or drug is known as addiction. Both physiological and psychological factors can lead to addiction. The psychology of addiction analyzes these factors and attempts to find ways of controlling addiction. The study of

HSC Physics Space 1. The Earth has a gravitational field that exerts a force on objects both on it and around it Define weight as the force on an object due to a gravitational field Mass is a measure of the amount of matter in an object‚ it is measured in kilograms (kg). The weight of an object is a measure of the force with which it is attracted by a gravitational force‚ it is measured in Newtons (N). It is directly related to the strength of the gravitational field at a point where the object
