When you apply a horizontal force of 50 N to a block, the block moves across the floor at a constant speed (μk = μs).

a. What happens if instead you apply a force of 41 N to the block initially at rest?

1. The block decelerates (the speed continually decreases).
2. The block doesn't move.
3. The block moves at a constant speed, but it moves more slowly.

b. When you apply a force of 41 N to the block initially at rest, what is the magnitude of the horizontal component of the force that the floor exerts on the block?
c. What happens if instead you exert a force of 53 N?

1. The block moves at a constant speed, but it moves faster.
2. The block doesn't move.
3. The block accelerates (the speed continually increases).

d. When you apply a force of 53 N, what is the magnitude of the horizontal component of the force that the floor exerts on the block?

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.
