Secondhand smoke (also known as environmental tobacco smoke) is the smoke a smoker breathes out and that comes from the tip of burning cigarettes‚ pipes‚ and cigars. It contains about 4‚000 chemicals. Many of these chemicals are dangerous; more than 50 are known to cause cancer. Anytime children breathe in secondhand smoke they are exposed to these chemicals. The American Academy Pediatrics (AAP) has conducted research on the effects of thirdhand smoke and found that it is also harmful. Thirdhand

In the paper I’m going to discuss the externalities of second-hand smoke. Externalities refer to all costs or benefits of a market activity borne by a third party. It’s also the difference between the social and private costs (benefits) of a market activity. When economic agents are not directly involved‚ negative externalities can exist‚ such as pollution. Second-hand smoke is a health hazard at any level (Essentials Of economics‚ Bradley R.Schiller). It’s to be said that smoking bans are the

(Hyperphysics.phy-astr.gsu.edu‚ 2014). Velocity (V) is a vector and is a measurement of speed. Speed is the distance travelled over the time it took to reach its destination. Velocity is the displacement of an object over the time taken (Burrows‚ 2007). The coefficient of restitution is the measurement of elasticity between two objects (Racquetresearch.com‚ 2014). In this extended experimental investigation the coefficient of restitution will be measured between a ball and the ground. Throughout this extended
