Acar travels down a straight country road that leads over hills and through valleys. on one particular stretch of road, the car encounters a hill that can be approximated as the top of a circle with a radius rh = 109 m. later, the car comes to a dip with a radius of curvature rd = 77 m. assume that the car maintains a constant speed of v = 23 m/s as it goes over the hill and through the dip. a)the actual weight of the driver, as measured on a flat stretch of road, is 535 n. what is the apparent weight of the driver at the top of the hill? b) what is the apparent weight of the driver at the bottom of the dip?

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

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.
