EXERCISE 6 1. A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25° downward from the horizontal. Find the work done by the shopper as she moves down a 50-m length of aisle. 1.6 kJ 2. A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the crate moves at constant speed‚ find (a) the work done by the 150-N force and (b) the coefficient of kinetic friction between the crate and surface. 900J

E = mc2 is a famous equation called mass–energy equivalence raised by Albert einstein ‚which explain the relationship between energy (E)and mass(m)‚c is represented constant number of light speed. E = mc2 theory of relativity theory and quantum mechanics are two basic branch of modern physics ‚ classical mechanics laid the foundation of classical physics ‚ but for high speed objects and microscopic condition of objects‚ Newton’s laws are no longer applicable. An important conclusion of the theory

The Business Cycle The long-run trend of the U.S. economy is one of economic growth. But growth has been interrupted by periods of economic instability usually associated with business cycles. Business cycles are alternating rises and declines in the level of economic activity‚ sometime over several years. Individual cycles (one “up” followed by one “down”) vary substantially in duration and intensity. Origin of the Idea O 26.1 Business cycles Phases of the Business Cycle Figure

This is particularly evident in sports gambling‚ most of which is illegal. Legal gambling is taxed and regulated and illegal gambling

The Roaring 20s The 1920’s were a time of prosperity‚ at least that’s what it looked like. In all reality it was a time of economic and social change. It was a time in which American morals declined and the government shifted to a more liberal government. Gone were the time off long dresses and the separation of the sexes.
