The figure above shows a boy swinging on a rope, starting at apoint higher than "a". consider the following distinct forces: 1. a downward force of gravity.2. a force exerted by the rope pointing from "a" to "o".3. a force in the direction of the boys motion.4. a force pointing from "o" to "a".which of the above forces are acting on the boy when he is inposition "a"? a)1 onlyb)1 and 2c)1 and 3

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.

What causes the development of most clouds and precipitation in the atmosphere?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
