Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (Ď = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.

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