A parsec is an astronomical unit of distance where 1 parsec= 3.26 light years (1 light year equals the distance travel by light in one year). If the speed of light is 186,000 mi/s, calculate the distance in meters of an object that travels 6.3 parsecs.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
