A72.0 kg man stands on a spring scale in an elevator. starting from rest, the elevator ascends, attaining its maximum speed of 1.70 m/s in 1.20 s. it travels with this constant speed for the next 5.00 s. the elevator then undergoes a uniform acceleration in the negative y-direction for 1.80 s and comes to rest.(a) what does the spring scale register before the elevator starts to move? (b) what does it register during the first 1.20 s? (c) what does it register while the elevator is traveling at a constant speed? (d) what does it register during the time it is slowing down?

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.
