2) distances near and beyond the solar system a) we discussed in class that the closest star besides the sun is alpha centauri, which is 4.4 light years away. if it takes 8 light minutes for the light to come from the sun to earth, and 4.4 years from alpha centauri, how much further is alpha centauri compared to the sun? b) how long would it take to get to alpha centauri if you were flying with a (science fiction) spaceship that goes at 1/1000th the speed of light? (discussed in class! ) c) how long would it take to get to alpha centauri with the fast current space craft, called juno, that goes at 266,000 km/h (or 165,000 mph)?

Humans have built artificial levees along the mississippi river to protect themselves and their property from floods. however, these structures also modify inland and coastal regions by disrupting the natural flow of sediment. artificial levees along the mississippi river a. reduce the amount of sediment deposited on floodplains and increase the amount of sediment deposited at the river's mouth. b. increase the amount of sediment deposited on floodplains and decrease the amount of sediment deposited at the river's mouth. c. increase the amount of sediment deposited on floodplains and at the river's mouth. d. decrease the amount of sediment deposited on floodplains and at the river's mouth.
