RUNNING HEAD: RESISTANCE TO LIBERALISM The Justification of Resisting Liberalism Liberalism‚ in general‚ was an ideological movement that emerged out of the ideas of the Enlightenment and the Industrial Revolution in the early 19th century. It embraced the ideas of individualism which were established in the Renaissance and Reformation era. The Renaissance period sparked a belief in the importance of the individual in society. It helped promote the beliefs of classical liberalism which

GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of wire. This magnetic flux is designated by Bi . The strength of the magnetic field induced by the current at the center of the loops of wire is given by Amperes law: Induced Bi = [pic]. where μo is the permeability of free space and has the value of 4π x 10-7 N/A2‚ N is the number of turns of wire‚ I is
