AIR POLLUTION [pic] Introduction The earth’s atmosphere‚ at or near sea level‚ consists approximately of 78 percent nitrogen‚ 21 percent oxygen and 1 percent other gases. If it were possible to remain in this state‚ 100 percent clean air would result. However‚ many varied sources allow other gases and particulates to mix with the clean air‚ causing our atmosphere to become unclean or polluted. Some of these pollutants are visible while others are invisible‚ with each

Research Investigation Safety features in cars Air Bags Air bags are safety features installed in cars so that upon collision the driver limits the damage that is inflicted on him/her. There are several different types of air bags. These include‚ Supplementary Restraint System (SRS)‚ an Air Cushion Restraint System (ACRS) and the Supplemental Inflatable Restraint (SIR). Air bags are commonly known for their rapid inflation upon a collision. They can inflate and deflate within 0.05 seconds
