Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf Īµ. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 Ļ, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

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 mendelās discoveries in genetics. over a century later, darwinās idea of evolution was modified in order to incorporate mendelās rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendelās rules of genetics and darwinās idea of biological evolution? a.)mendelās genetics states laws that are now part of the theory of biological evolution. b.)biological evolution states laws that are part of mendelās theory of genetics. c.)mendelās genetics replaced darwinās entire concept of biological evolution. d.)biological evolution is a law that explains why all genetics exist.
