As you watch the flood in progress, you can watch cars float away one-by-one. I hope that this gives you pause before you yourself consider driving across a flooded roadway. The topic here is how much running water does it take to make a SUV (sport utility vehicle) or pick-up truck to float away. Water weights 62.4 pounds per cubic foot. Given typical velocities of water running across sloped roadways, for each foot the water rises, about 500 pounds of lateral force is applied and the a typical vehicle volume displaces about 1500 pounds of water. This means that the car weights 1500 pounds less for each foot the water rises. A typical pickup truck weighs about 5000 pounds, while a Suburban weights about 5500 pounds. A car like a Civic weighs about 3000 pounds. QUESTION: what is the height of water needed to float a Civic (divide the weight by 1500)

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
