On a Saturday afternoon, you decide to pay a neighborhood kid to mow your lawn. The kid usesa manual push lawn mower with a mass of m=12 kg. The handle of the lawnmower is tiltedθ=53 degrees with respect to the vertical and the coefficient of kinetic friction between thelawnmower and the ground is μk=0.16. Assume that the kid is pushing parallel to the handle. A.Find an expression for much power the kid supplies to the lawnmower (Pkid) if thelawnmower is moving at a constant speed of vo=1.5 m/s. B.Find the numerical value for Pkid

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? mendel’s genetics states laws that are now part of the theory of biological evolution. biological evolution states laws that are part of mendel’s theory of genetics. mendel’s genetics replaced darwin’s entire concept of biological evolution. biological evolution is a law that explains why all genetics exist
