Suppose that the strength of the electric field about an isolated point charge has a certain value at a distance of 4 m. how will the electric field strength compare at a distance of 8 m from the point charge? 1. at twice the distance the field strength will be twice the original value. 2. at twice the distance the field strength will be 1 3 of the original value. 3. at twice the distance the field strength will be 1 2 of the original value. 4. at twice the distance the field strength will be 1 4 of the original value. 5. at twice the distance the field strength will be the same.

The mass of a bowling ball is 10 kg and the mass of a ping pong ball is 0.015 kg. if the two objects are 5 meters apart, what is the gravitational force ?

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.
