Apitching machine is programmed to pitch baseballs horizontally at a speed of 83 mph . the machine is mounted on a truck and aimed backward. as the truck drives away from a man at a speed of 65 mph , the machine shoots a ball towards him.

a truck drives away from a man holding a baseball glove. a pitching machine in the bed of the truck pitches a baseball towards the man.

determine the correct relative speed for each object pair.

the speed of the pitching machine relative to the truck
the speed of the pitched ball relative to the truck
the speed of the pitching machine relative to the man
the speed of the pitched ball relative to the man

The experiments with static charges were done by:

The frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?

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.
