#1 Linear accelerators are used in physics for accelerating charged particles. Suppose that an alpha particle enters an accelerator and undergoes a constant acceleration that increases the speed of the particle from 103 m/scc to 104 m/sec in 103I sec. Find the acceleration a and the distance traveled during that period of Ill":i sec. #2 Exponential growth. If the growth rate of the number of bacteria at any time t is proportional to the number present at t and doubles in 1 week. how many bacteria can be expected aer 2 weeks? After 4 weeks? #3 Dryer. If a wet sheet in a dryer loses its moisture at a rate proportional to its moisture content, and if it loses half of its moisture during the rst 10 min of drying, when will it have lost 99% of its moisture (to be practically dry)
