The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost

PHYSICS WORK SHEET - 2 CLASS – IX LESSON : MOTION 1. Analyze the following situation and answer the following questions. A circular track has a circumference of 3140m with AB as one of its diameter. A man riding a scooter moves from A to B along the circular path with a uniform speed of 10 m/s. a) Distance covered by the man b) Displacement of the man c) Time taken by the man in reaching from A to B. 2. A car starting from rest moves with a uniform acceleration of 0.1 m/s2 for 2 minutes. Find the

Equilibrium Essay How does Equilibrium fulfil the conventions of a dystopic text? In what way does it subvert them? 1000-1500 words. A dystopia is a futuristic and technologically advanced oppressive world with an overbearing totalitarian government who maintain strict authoritarian control over its population. Dystopia’s are often concealed as utopias since everybody appears to be equal and life appears to be fair‚ but in reality freedom is greatly restricted under a dystopia. Kurt Wimmer’s Equilibrium

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

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

TOPIC - 2 DEMAND‚ SUPPLY AND MARKET EQUILIBRIUM The term ‘price’ has a great relevance in economics. In ordinary usage‚ price is the quantity of payment or compensation given by one party to another in return for goods and services. It is generally expressed in terms of units of some form of currency. But how does a product sell for a certain price‚ what constitutes the price of a product and how is the price determined is the bigger question. In economics‚ for a competitive market
