dielectric constant and dielectric loss were measured within the frequency range from 10 Hz to 106 Hz and the temperature ranging from 50°C to 300°C. The results showed that the dielectric constant and dielectric loss of the sample are frequency dependent and temperature dependent. Dielectric constant and dielectric loss increases with decreasing frequency and increasing temperature due to interfacial polarization. Introduction: Dielectric materials with high dielectric constant‚ good thermal

1. Determine the spring constant‚ k‚ of Spring 1‚ by using Hooke’s Law. Take three different measurements (since 3 masses) and do three calculations and average your k’s to get a more accurate answer. By applying lots of friction‚ you will be able to get your mass to hang still. Show a table of your data and your calculations of k. Spring 1 with three different masses: 50 grams: Spring stretched: 5m F = 50gm * 9.8 m/s2 = 490.00 N K= 490/5m = 98 100 grams: Spring stretched: 10m F = 100gm * 9

The Constant Gardener is a 2005 drama film directed by Fernando Meirelles and produced by Simon Channing-Williams . The screen script by Jeffrey Caine is based on the John le Carre novel by the same name. The movie is the narrative of Justin Quayle‚ a British diplomat in Kenya‚ who seeks to find the truth behind his wife’s murder . The movie‚ set in the 1990’s‚ begins almost with the murder‚ however‚ with the use of flashbacks one is given a glimpse of the life the couple had before the ending

There once lived a great mathematician in a village outside Ujjain . He was often called by the local king to advice on matters related to the economy. His reputation had spread as far as Taxila in the North and Kanchi in the South. So it hurt him very much when the village headman told him‚ "You may be a great mathematician who advises the king on economic matters but your son does not know the value of Gold or silver. The mathematician called his son and asked‚ "What is more valuable - gold

Problem: For the reaction H2(g) + I2(g) ↔ 2 HI(g) At equilibrium‚ the concentrations are found to be [H2] = 0.106 M [I2] = 0.035 M [HI] = 1.29 M What is the equilibrium constant of this reaction? Solution The equilibrium constant (K) for the chemical equation aA + bB ↔ cC + dD can be expressed by the concentrations of A‚B‚C and D at equilibrium by the equation K = [C]c[D]d/[A]a[B]b For this equation‚ there is no dD so it is left out of the equation. K = [C]c/[A]a[B]b
