Abicyclist initially travels at a steady 8 m/s for 100 seconds on a straight level road, and then takes 40 seconds to slow to 5 m/s. three english majors discussing this situation make the following contentions about the bicycle's kinetic energy. with which, if any, do you agree?

a. axel: "the bicycle is just going to slow down naturally. it doesn't take any work for something to slow down."
b. bram: "i disagree. the speed of the bike decreased, so there is a change in kinetic energy. that means work was done on the bike."
c. cassie: "i think axel is right that no work was done, but i don't agree with his reason. there is no work being done here because there are no external forces being exerted."
d. none of them are correct. back to physics for them all!

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.
